🥇SMS ka nānā ʻana i ke kaumaha o ʻekolu hives no $30

ʻAʻole, ʻaʻole kēia he hāʻawi pāʻoihana, ʻo ia ke kumukūʻai o nā ʻāpana ʻōnaehana hiki iā ʻoe ke hōʻuluʻulu ma hope o ka heluhelu ʻana i ka ʻatikala.

ʻO kahi kumu liʻiliʻi:

I kekahi manawa i hala aku nei ua hoʻoholo wau e kiʻi i ka nalo, a ua ʻike ʻia lākou ... no ke kau holoʻokoʻa, akā ʻaʻole i haʻalele i ka hale hoʻoilo.
A ʻo kēia me ka ʻoiaʻiʻo e hana pono ana ʻo ia i nā mea āpau - ʻo ka hāʻule hoʻohui ʻana i ka meaʻai, ka insulation ma mua o ke anuanu.
ʻO ka hive he ʻōnaehana lāʻau "Dadan" maʻamau me 10 mau papa i hana ʻia me nā papa 40 mm.
Akā ʻo kēlā hoʻoilo, ma muli o ka piʻi ʻana o ka mahana, ʻoi aku ka nalowale o nā beekeepers ʻike ma mua o ka mea maʻamau.

ʻO kēia ke ʻano o ka manaʻo o kahi ʻōnaehana no ka nānā ʻana i ke ʻano o ka hive.
Ma hope o ka paʻi ʻana i kekahi mau ʻatikala ma Habr a me ke kamaʻilio ʻana ma ka hui beekeepers, ua hoʻoholo wau e hele mai ka maʻalahi a i ka paʻakikī.
ʻO ke kaumaha wale nō ka mea i hoʻopaʻapaʻa ʻole ʻia, akā ma ke ʻano he kānāwai, nānā nā ʻōnaehana i hoʻokahi hive "reference".
Inā hele hewa kekahi mea (e like me ka haʻalele ʻana o kahi pūʻulu, maʻi pi), a laila lilo nā mea hōʻailona i mea ʻole.

No laila, ua hoʻoholo ʻia e nānā i ka loli o ke kaumaha o ʻekolu hives i ka manawa hoʻokahi me ka hoʻohana ʻana i hoʻokahi microcontroller, a hoʻohui i nā "maikaʻi" ʻē aʻe ma hope.
ʻO ka hopena he ʻōnaehana kūʻokoʻa me ka manawa hana ma kahi o hoʻokahi mahina ma ka uku hoʻokahi o ka pākaukau 18650 a hoʻouna i nā helu helu hoʻokahi i ka lā.
Ua hoʻāʻo wau e hoʻomaʻamaʻa i ka hoʻolālā i hiki ke hana hou ʻia me ka ʻole o nā kiʻi, mai nā kiʻi wale nō.

ʻO ka loiloi hana penei: i ka wā o ka hoʻomaka mua / hoʻonohonoho hou ʻana, mālama ʻia nā heluhelu o nā sensor i hoʻokomo ʻia ma lalo o nā hives ma EEPROM.
A laila, i kēlā me kēia lā, ma hope o ka napoʻo ʻana o ka lā, "ala" ka ʻōnaehana, heluhelu i nā heluhelu a hoʻouna i kahi SMS me ka loli o ke kaumaha no ka lā a mai ka manawa i hoʻohuli ʻia.
Eia kekahi, ua hoʻouna ʻia ke kumukūʻai uila uila, a i ka wā e hāʻule ai i 3.5V, ua hoʻopuka ʻia kahi ʻōlelo aʻo e pili ana i ka pono e hoʻopiʻi, no ka mea ma lalo o 3.4V ʻaʻole e hoʻāla ka module kamaʻilio, a ʻo ka heluhelu ʻana i ke kaumaha ua "lele".

"Ke hoʻomanaʻo nei ʻoe i ka hoʻomaka ʻana o ia mea. ʻO nā mea a pau no ka manawa mua a hou. "

ʻAe, ʻo kēia ka pūʻulu o nā lako i hana mua ʻia, ʻoiai ʻo nā kānana a me nā uwea wale nō i ola a hiki i ka hopena hope, akā ʻo ka mea mua.
ʻO ka ʻoiaʻiʻo, ʻaʻole pono ʻoe i kahi kaula wili, ua hoʻololi wale ʻia ke kumukūʻai like me ka 30m pololei.

Inā ʻaʻole ʻoe makaʻu i ka wehe ʻana i nā LED 3 SMD a me ka hapalua haneli o ka soldering maʻamau (output), a laila e hele!

No laila, pono mākou i ka hoʻonohonoho ʻana o nā lako / mau mea:

Arduino Pro Mini 3V
Pono ʻoe e hoʻolohe i ka linear converter microcircuit - pono ia 3.3V - ma ka chip e kaha ana i ka KB 33/LB 33/DE A10 - ua hewa kaʻu Pākē, a ʻo ka pūʻulu holoʻokoʻa.
ʻO nā papa i loko o ka hale kūʻai i loaʻa iā 5-volt regulators a me 16MHz crystals.
ʻO USB-Ttl ma kahi chip CH340 - hiki iā ʻoe ke hoʻohana i kahi 5-volt, akā i ka wā e ʻā ana i ka microcontroller, pono e wehe ʻia ka Arduino mai ka module GSM i ʻole e puhi i ka hope.
ʻAʻole hana nā papa e pili ana i ka chip PL2303 ma lalo o Windows 10.
Module kamaʻilio GSM Goouu Tech IOT GA-6-B a i ʻole AI-THINKER A-6 Mini.
No ke aha ʻoe i kū ai i laila? ʻO Neoway M590 - kahi mea hoʻolālā e koi ana i nā hula kaʻawale me nā pahu kani, ʻo GSM SIM800L - ʻaʻole makemake i ka pae 2.8V maʻamau ʻole, e koi ana i ka hoʻonohonoho ʻana me kahi Arduino ʻekolu-volt.
Eia kekahi, ʻo ka hopena mai AiThinker he liʻiliʻi ka hoʻohana ʻana i ka ikehu (ʻaʻole au i ʻike i kahi kiʻekiʻe ma mua o 100mA i ka wā e hoʻouna ai i ka SMS).
GSM GPRS 3DBI antenna (ma ke kiʻi ma luna - he scarf rectangular me kahi "huelo", i ka hola 9)
Puke hoʻomaka o kahi mea hoʻohana me ka uhi maikaʻi ma kahi o kāu apiary.
ʻAe, pono e hoʻāla mua ʻia ka pūʻolo ma ke kelepona maʻamau, disable the PIN REQUEST ma ke komo ʻana, a hoʻonui i kāu moʻokāki.
I kēia manawa he nui nā koho me nā inoa i ke ʻano o "Sensor", "IoT" - he haʻahaʻa haʻahaʻa ko lākou uku.
uea dupont 20cm wahine-wahine - 3 pcs. (e hoʻohui iā Arduino me USB-TTL)
3 pcs. HX711 - ADC no nā unahi
6 ukana ukana no ke kaumaha a hiki i 50kg
15 mika o 4-core kelepona kelepona - no ka hoʻohui ʻana i nā modula kaumaha me ARDUINO.
Photoresistor GL5528 (ʻo ia ka mea nui, me ka pale ʻeleʻele o 1 MΩ a me ke kūpaʻa māmā o 10-20 kΩ) a me ʻelua mau pale 20 kΩ maʻamau.
ʻO kahi ʻāpana ʻaoʻao ʻelua "mānoanoa" lipine 18x18mm - no ka hoʻopili ʻana i ka Arduino i ka module kamaʻilio.
ʻO ka 18650 paʻa pākaukau a, ʻoiaʻiʻo, ʻo ka pākaukau ponoʻī he ~ 2600mAh.
ʻO kahi wax liʻiliʻi a i ʻole paraffin (kukui kukui-papa) - no ka pale ʻana i ka wai HX711
He ʻāpana kaola lāʻau 25x50x300mm no ke kumu o nā ana kānana.
He ʻumikūmālua mau wili paʻi ponoʻī me kahi mea holoi paʻi 4,2x19 mm no ka hoʻopili ʻana i nā mea ʻike i ke kumu.

Hiki ke lawe ʻia ka pākaukau mai ka wehe ʻana o nā kamepiula - ʻoi aku ka maikaʻi ma mua o ka mea hou, a ʻoi aku ka nui o ka mana ma mua o ka Chinese UltraFire - loaʻa iaʻu ka 1500 versus 450 (ʻo 6800 kēia no ke ahi 😉

Eia kekahi, pono ʻoe i nā lima paʻa, kahi hao hao EPSN-25, rosin a me POS-60 solder.

ʻOiai ʻo 5 mau makahiki i hala aku nei ua hoʻohana au i ka hao hao Soviet me kahi kihi keleawe (ʻaʻole i hana nā hale kūʻai noʻu - ua lawe au iā ia no ka hoʻāʻo ʻana a hoʻopau i ke kaapuni me kahi EPSN).
Akā ma hope o kona hāʻule ʻana a me kekahi mau mea hoʻopunipuni Kina, ua kapa ʻia ka mea hope ʻo Sparta - kahi mea koʻikoʻi e like me kona inoa, ua kū.
ma kahi huahana me kahi thermostat.

No laila e hele kāua!

No ka hoʻomaka ʻana, wehe mākou i ʻelua mau LED mai ka module GSM (kahi i kū ai lākou i hoʻopuni ʻia i kahi oval ʻalani)
Hoʻokomo mākou i ke kāleka SIM me nā pā pili i ka papa kaapuni i paʻi ʻia, hōʻike ʻia ke kihi beveled i ke kiʻi e kahi pua.

A laila, hana mākou i kahi kaʻina hana like me ka LED ma ka papa Arduino (oval ma ka hema o ka pahu square),
Hoʻopili i ka pū i ʻehā mau mea pili (1),
Lawe mākou i ʻelua mau mea pale 20k, wili i nā alakaʻi ma kekahi ʻaoʻao, e hoʻopili i ka wili i loko o ka lua o ka pine A5, ʻo nā alakaʻi i koe i RAW a me GND o ka arduino (2),
Hoʻopōkole mākou i nā wāwae o ka photoresistor i 10mm a kūʻai aku iā ia i nā pine GND a me D2 o ka papa (3).

ʻO ka manawa kēia no ka lipine uila polū o ka lipine ʻaoʻao ʻelua - hoʻopili mākou i ka mea paʻa kāleka SIM o ka module kamaʻilio, a ma luna - ʻo Arduino - ke pihi ʻulaʻula (kālā) ke alo iā mākou a aia ma luna o ke kāleka SIM.

Kūleʻa mākou i ka lako mana: hoʻohui ʻia mai ka capacitor module communication (4) i ka pine RAW arduino.
ʻO ka ʻoiaʻiʻo ʻo ka module kamaʻilio ponoʻī e koi i ka 3.4-4.2V no kāna lako mana, a ua pili kona pilina PWR i kahi mea hoʻololi i lalo, no laila e hoʻohana ʻia mai ka li-ion, pono e hāʻawi ʻia ka uila ma ke ala ʻana i kēia ʻāpana o ke kaapuni.

Ma Arduino, ma kahi ʻē aʻe, hāʻawi mākou i ka mana ma o ka mea hoʻololi laina - ma ka hoʻohana haʻahaʻa o kēia manawa, ʻo ka hāʻule ʻana o ka uila he 0.1V.
Akā, ma ka hāʻawi ʻana i ka volta paʻa i nā modula HX711, hoʻopau mākou i ka pono e hoʻololi iā lākou i kahi haʻahaʻa haʻahaʻa (a i ka manawa like mai ka hoʻonui ʻana i ka walaʻau ma muli o kēia hana).

A laila, kūʻai mākou i nā lele lele (5) ma waena o nā pine PWR-A1, URX-D4 a me UTX-D5, GND-G lepo (6) a me ka mana hope loa mai ka 18650 paʻa pahu (7), hoʻohui i ka antenna (8).
I kēia manawa, lawe mākou i kahi mea hoʻololi USB-TTL a hoʻopili i nā pilina RXD-TXD a me TXD-RXD, GND-GND me nā uea Dupont iā ARDUINO (comb 1):

Hōʻike ka kiʻi ma luna i ka mana mua (o ʻekolu) o ka ʻōnaehana, i hoʻohana ʻia no ka debugging.

Akā i kēia manawa e hoʻomaha mākou mai ka hao hao no kekahi manawa a neʻe aku i ka ʻāpana polokalamu.
E wehewehe au i ke ʻano o nā hana no Windows:
ʻO ka mea mua, pono ʻoe e hoʻoiho a hoʻouka / wehe i ka polokalamu IDE Arduino — ʻo 1.8.9 ka mana o kēia manawa, akā hoʻohana au i ka 1.6.4

No ka maʻalahi, wehe mākou i ka waihona i loko o ka waihona C: arduino - "kou_version_number", i loko e loaʻa iā mākou nā folder / dist, nā mea hoʻokele, nā hiʻohiʻona, hardware, java, lib, nā hale waihona puke, nā kuhikuhi, nā mea hana, a me ka file executable arduino. (ma waena o nā mea ʻē aʻe).

I kēia manawa pono mākou i kahi waihona e hana pū me ka ADC HX711 — pihi ʻōmaʻomaʻo "clone a hoʻoiho" - hoʻoiho i ka ZIP.
Hoʻokomo ʻia nā mea i loko (folder HX711-master) i ka papa kuhikuhi C: arduino- "kou_version_number" hale waihona puke.

A ʻoiaʻiʻo ka mea hoʻokele no USB-TTL mai ka github like - mai ka waihona i wehe ʻole ʻia, hoʻomaka wale ʻia ka hoʻonohonoho ʻana me ka faila SETUP.

ʻAe, e hoʻomaka a hoʻonohonoho i ka papahana C: arduino- "kou_version_number" arduino

E hele i ka mea "Tools" - koho i ka papa "Arduino Pro or Pro Mini", Atmega 328 3.3V 8 MHz processor, port - kahi helu ʻē aʻe ma mua o ka ʻōnaehana COM1 (ʻike ʻia ma hope o ka hoʻokomo ʻana i ka mea hoʻokele CH340 me kahi adapter USB-TTL. pili)

ʻAe, kope i kēia kiʻi kiʻi (polokalamu) a hoʻopili iā ia i ka puka makani Arduino IDE

ʻAe, ʻoi aku ka pololei o kēia ʻano, akā paʻakikī ke noʻonoʻo e kūkulu nā pi i nā papa āpau me nā "ʻōlelo" o nā honeycombs ma kekahi paia o ka hive.

No laila, ke manaʻo nei au e hoʻohaʻahaʻa i nā mea ʻike i ke kiko 5 - a laila ʻaʻohe pono e pale i ka ʻōnaehana, a i ka wā e hoʻohana ai i nā hives māmā, pono pono e hana me hoʻokahi sensor.

Ma keʻano laulā, ua hoʻāʻo mākou i ʻelua ʻano modules ma ka HX711, ʻelua mau ʻano ʻike, a me nā koho ʻelua no ka hoʻopili ʻana iā lākou - me kahi alahaka Wheatstone piha (2 sensors) a me ka hapalua, ke hoʻohui ʻia ka ʻāpana ʻelua me 1k resistors me kahi ka hoʻomanawanui o 0.1%.
Akā ʻaʻole makemake ʻia ke ala hope a ʻaʻole i ʻōlelo ʻia e nā mea hana sensor, no laila e wehewehe wau i ka mea mua.

No laila, no hoʻokahi hive e hoʻokomo mākou i ʻelua kānana kānana a me hoʻokahi module HX711, ʻo ke kiʻi wili e like me kēia:

Aia he 5 mika o 4-wire kelepona uwea mai ka papa ADC a i ka Arduino - Hoʻomanaʻo mākou i ka makemake ʻole o nā pi i nā mea GSM i loko o ka hive.

Ma keʻano laulā, waiho mākou i ka "huelo" 8cm ma nā meaʻike, e wehe i ka hui wili a kūʻai i nā mea a pau e like me ke kiʻi ma luna.

Ma mua o ka hoʻomaka ʻana i ka ʻāpana kamana, e kau i ka wax/paraffin i loko o kahi pahu kūpono e hoʻoheheʻe ai i loko o kahi ʻauʻau wai.

I kēia manawa, lawe mākou i kā mākou lāʻau a māhele i ʻekolu ʻāpana o 100mm kēlā me kēia

A laila, hōʻailona mākou i kahi ʻāpana longitudinal 25 mm ākea, 7-8 mm hohonu, e hoʻoneʻe i ka nui me ka hacksaw a me ka chisel - pono e puka mai kahi ʻano U.

Ua hoʻomehana ʻia ka wax? — Hoʻopaʻa mākou i kā mākou mau papa ADC ma laila - e pale aku kēia iā lākou mai ka makū/ohu:

Hoʻonoho mākou i nā mea āpau ma kahi kumu lāʻau (pono e mālama ʻia me kahi antiseptic e pale ai i ka pala):

A ʻo ka hope, hoʻoponopono mākou i nā mea ʻike me nā wili paʻi ponoʻī:

Aia kekahi koho me ka lipine uila polū, akā no nā kumu o ke kanaka ʻaʻole wau e hōʻike nei 😉

Mai ka ʻaoʻao Arduino hana mākou i kēia:

Wehe mākou i nā uwea kelepona, wili i nā uwea kala, a paʻa.

Ma hope o kēlā, kūʻai aku i nā mea pili i ka papa e like me ke kiʻi:

ʻO ia, i kēia manawa no ka nānā hope, hoʻokomo mākou i nā mea ʻike i nā ʻāpana o ka pōʻai, kahi ʻāpana plywood ma luna, hoʻonohonoho hou i ka mea hoʻoponopono (kau mākou i kahi pākaukau me kahi pāpale peni ma ka photodiode).

I ka manawa like, pono ke kukui o ka LED ma Arduino a hiki mai kahi SMS ho'āʻo.

A laila, wehe i ka pāpale mai ka photocell a hele e hoʻopiha i ka wai i loko o kahi ʻōmole plastik 1.5 lita.
Hoʻokomo mākou i ka ʻōmole ma ka plywood a inā ua hala kekahi mau minuke mai ka wā i hoʻāla ʻia ai, hoʻihoʻi mākou i ka pāpale ma luna o ka photoresistor (hoʻohālike i ka napoʻo ʻana o ka lā).

Ma hope o ʻekolu mau minuke, e hoʻomālamalama ʻia ka LED ma Arduino, a pono ʻoe e loaʻa i kahi SMS me nā koina kaumaha ma kahi o 1 kg ma nā kūlana āpau.

Hoʻomaikaʻi! Ua hui maikaʻi ʻia ka ʻōnaehana!

Inā hoʻoikaika mākou i ka ʻōnaehana e hana hou, a laila e loaʻa i ke kolamu kaumaha mua nā zeros.

ʻAe, ma nā kūlana maoli, pono e hoʻonohonoho pono i ka photoresistor i luna.

I kēia manawa e hāʻawi wau i kahi manual mea hoʻohana pōkole:

E hoʻouka i nā anana kānana ma lalo o nā paia hope o nā hives (e kau i kahi kaola/papa ~30mm mānoanoa ma lalo o nā mua)
Hoʻolulu i ka photoresistor a hoʻokomo i ka pākaukau - pono ke kukui uila a loaʻa iā ʻoe kahi SMS hoʻāʻo me ka kikokikona "INITIAL BOOT OK"
E kau i ka wae waena ma kahi mamao loa mai nā hives a i ʻole e hoʻopilikia nā uea i ka wā e hana ai me nā pi.
I kēlā me kēia ahiahi, ma hope o ka napoʻo ʻana o ka lā, e loaʻa iā ʻoe kahi SMS me kāu hoʻololi kaumaha no ka lā a mai ka manawa hoʻomaka.
Ke piʻi ka uila uila i 3.5V, e pau ka SMS me ka laina "!!! E hoʻopaʻa i ka pākaukau!!!"
ʻO ka manawa hana ma kahi pākahi 2600mAh ma kahi o hoʻokahi mahina.
Inā hoʻololi ʻia ka pākaukau, ʻaʻole hoʻomanaʻo ʻia nā loli o kēlā me kēia lā i ke kaumaha o nā hives.

He aha ka mea e hiki mai ana?

E noʻonoʻo pehea e hoʻokomo ai i kēia mau mea āpau i kahi papahana no github
E hoʻomaka i 3 mau ʻohana nalo i loko o nā hives o ka ʻōnaehana Palivoda (a i ʻole nā horned i loko o nā kānaka)
Hoʻohui i nā "buns" - e ana i ka haʻahaʻa, ka mahana, a ʻo ka mea nui loa - ka nānā ʻana i ke kani ʻana o nā pi.

ʻO ia wale nō i kēia manawa, me kou ʻoiaʻiʻo, e ke kahu pipi uila Andrey
