N'ozuzu, a nwalere ụdị modulu abụọ na HX711, ụdị sensọ abụọ, na nhọrọ abụọ maka njikọ ha - na akwa Wheatstone zuru ezu (2 sensọ) na ọkara, mgbe akụkụ nke abụọ na-agbakwunye na 1k resistors na a. nnabata nke 0.1%.
Ma usoro nke ikpeazụ bụ ihe na-adịghị mma ma ghara ịkwado ọbụna site na ndị na-emepụta ihe mmetụta, n'ihi ya, m ga-akọwa nanị nke mbụ.

Yabụ, n'otu ekwo Ekwo anyị ga-etinye sel ibu abụọ na otu HX711 modul, eserese wiring bụ nke a:

Site na bọọdụ ADC ruo arduino enwere mita 5 nke eriri ekwentị 4-isi - anyị na-echeta otú aṅụ adịghị amasị GSM ngwaọrụ na ekwo Ekwo.

N'ozuzu, anyị na-ahapụ "ọdụ" nke 8 cm nke ọ bụla na sensọ, hichaa ụzọ gbagọrọ agbagọ ma wepụ ihe niile dị ka ọ dị na foto dị n'elu.

Tupu ịmalite ọrụ nka, tinye wax/paraffin n'ime akpa kwesịrị ekwesị iji gbazee n'ime mmiri ịsa ahụ.

Ugbu a, anyị na-ewere osisi anyị ma kewaa ya n'ime akụkụ atọ nke 100mm nke ọ bụla

Na-esote, anyị na-akara oghere ogologo 25 mm n'obosara, 7-8 mm miri emi, site n'enyemaka nke hacksaw na chisel anyị na-ewepu ngafe - profaịlụ p-ụdị kwesịrị ịpụta.

Waks ahụ agbaala ọkụ? - anyị na-etinye bọọdụ ADC anyị n'ebe ahụ - nke a ga-echebe ha pụọ na mmiri / ikuku:

Anyị na-etinye ya niile na ntọala osisi (ọ dị mkpa ka a gwọọ ya na antiseptik si ire ere):

N'ikpeazụ, anyị na-edozi sensọ na skru nke onwe:

Enwere nhọrọ ọzọ nwere teepu eletrọnịkị na-acha anụnụ anụnụ, mana maka ebumnuche mmadụ, anaghị m ewepụta ya 😉

Site n'akụkụ Arduino, mee ihe ndị a:

Anyị na-ehicha eriri telifon anyị, na-atụgharị wired ndị nwere agba ọnụ, na-egwu aghụghọ.

Mgbe ahụ, solder na kọntaktị nke osisi dị na foto:

Nke ahụ bụ ya, ugbu a maka nlele ikpeazụ, anyị na-etinye sensọ na ngalaba nke gburugburu, n'elu - mpempe plywood, megharịa onye njikwa (anyị na-etinye batrị na mkpịsị pen na photodiode).

N'otu oge ahụ, LED na arduino kwesịrị ịnya isi na SMS ule kwesịrị ịbịa.

Mgbe ahụ, anyị na-ewepụ okpu ahụ na fotocell, ma gaa na-anakọta mmiri na karama plastik 1.5 lita.
Anyị na-etinye karama ahụ na plywood ma ọ bụrụ na ọtụtụ nkeji agafeela site na ịgbanwuo, anyị na-etinye okpu azụ na fotoresistor (na-eme ka ọdịda anyanwụ).

Mgbe nkeji atọ gachara, LED na arduino ga-enwu, ma ị ga-enweta SMS nwere ụkpụrụ ịdị arọ nke ihe dị ka kilogram 1 n'ọnọdụ niile.

Ekele! achịkọtala usoro ahụ nke ọma!

Ọ bụrụ na anyị na-amanye usoro ahụ ka ọ rụọ ọrụ ọzọ, mgbe ahụ, efu ga-enweta na kọlụm mbụ nke ibu.

Ee, na ezigbo ọnọdụ ọ bụ ihe na-achọsi ike iji tụgharịa fotoresistor kwụ ọtọ elu.

Ugbu a, m ga-enye obere akwụkwọ ntuziaka maka ojiji:

Wụnye sel ibu n'okpuru mgbidi azụ nke hives (dochie oghere / bọọdụ ~ 30 mm gbara ọkpụrụkpụ n'okpuru ndị dị n'ihu)
Debe fotoresistor ma tinye batrị n'ime ya - LED kwesịrị ịnya isi na SMS ule ga-eji ederede "INITIAL BOOT OK"
Debe ihe mgbochi etiti na ebe kachasị anya site na hives na ka wires ghara igbochi mgbe ị na-arụ ọrụ na aṅụ.
N'uhuruchi ọ bụla, mgbe anyanwụ dara, SMS ga-abịa na mgbanwe ịdị arọ kwa ụbọchị yana kemgbe mmalite.
Mgbe voltaji batrị ruru 3.5V, SMS ga-ejedebe na ahịrị "!!! Ịchaji batrị!!!"
Oge ọrụ site na otu batrị nwere ikike nke 2600mAh bụ ihe dịka otu ọnwa.
N'ọnọdụ nke nnọchi batrị, anaghị echeta mgbanwe ịdị arọ nke hives kwa ụbọchị.

Kedu ihe ọzọ?

Chọpụta otu esi ahazi ihe ndị a niile na oru ngo maka github
Nwee mpaghara aṅụ 3 na hives nke usoro Palivoda (ma ọ bụ mpi na ndị mmadụ)
Tinye "buns" - nha iru mmiri, okpomọkụ, na nke kachasị mkpa - nyocha nke mkpọtụ aṅụ.
