Nigbamii ti, a samisi iho gigun kan 25 mm fife, 7-8 mm jin, yọkuro apọju nipa lilo hacksaw ati chisel - profaili U-sókè yẹ ki o farahan.

Ṣe epo-eti gbona? - a tẹ awọn igbimọ ADC wa nibẹ - eyi yoo daabobo wọn lati ọrinrin / kurukuru:

A gbe gbogbo rẹ si ipilẹ onigi (o gbọdọ ṣe itọju pẹlu apakokoro lati ṣe idiwọ rotting):

Ati nikẹhin, a ṣe atunṣe awọn sensọ pẹlu awọn skru ti ara ẹni:

Aṣayan tun wa pẹlu teepu itanna bulu, ṣugbọn fun awọn idi ti eniyan Emi ko ṣe afihan rẹ 😉

Lati ẹgbẹ Arduino a ṣe atẹle naa:

A bọ́ àwọn kebulu tẹlifóònù wa, a máa ń yí àwọn waya aláwọ̀ náà pa pọ̀, a sì ń gé wọn.

Lẹhin iyẹn, solder si awọn olubasọrọ igbimọ bi ninu fọto:

Iyẹn ni, ni bayi fun ayẹwo ikẹhin, a fi awọn sensọ sinu awọn apa ti Circle, nkan ti plywood lori oke, tunto oluṣakoso naa (a fi batiri kan pẹlu fila pen lori photodiode).

Ni akoko kanna, LED lori Arduino yẹ ki o seju ati SMS idanwo yẹ ki o de.

Nigbamii, yọ fila kuro lati inu photocell ki o lọ kun omi sinu igo ṣiṣu 1.5 lita kan.
A fi igo naa sori itẹnu ati pe ti awọn iṣẹju pupọ ba ti kọja lẹhin ti o ti wa ni titan, a fi fila naa pada sori photoresistor (simulating Iwọoorun).

Lẹhin iṣẹju mẹta, LED lori Arduino yoo tan, ati pe o yẹ ki o gba SMS kan pẹlu awọn iye iwuwo ti o to 1 kg ni gbogbo awọn ipo.

Oriire! Eto naa ti ṣajọpọ ni aṣeyọri!

Ti a ba fi agbara mu eto naa lati ṣiṣẹ lẹẹkansi, lẹhinna iwe iwuwo akọkọ yoo ni awọn odo.

Bẹẹni, ni awọn ipo gidi o ni imọran lati ṣe itọsọna photoresistor ni inaro si oke.

Bayi Emi yoo fun ni kukuru kukuru kan:

Fi awọn iwọn igara sori ẹrọ labẹ awọn odi ẹhin ti awọn hives (gbe tan ina kan / ọkọ ~ 30mm nipọn labẹ awọn iwaju)
Boji photoresistor ki o fi batiri sii - LED yẹ ki o seju ati pe o yẹ ki o gba SMS idanwo kan pẹlu ọrọ “BOOT INITIAL OK”
Gbe awọn aringbungbun kuro ni awọn ti o pọju ijinna lati awọn hives ati ki awọn onirin ko ba dabaru nigbati ṣiṣẹ pẹlu awọn oyin.
Ni gbogbo irọlẹ, lẹhin iwọ-oorun iwọ yoo gba SMS kan pẹlu awọn ayipada iwuwo rẹ fun ọjọ naa ati lati akoko ifilọlẹ.
Nigbati foliteji batiri ba de 3.5V, SMS yoo pari pẹlu laini “!!! BATIRI GBAJA!!!"
Akoko iṣẹ lori batiri 2600mAh kan jẹ bii oṣu kan.
Ti batiri ba rọpo, awọn iyipada ojoojumọ ni iwuwo ti awọn hives ko ni iranti.

Ohun ti ni tókàn?

Ṣe apejuwe bi o ṣe le fi gbogbo eyi sinu iṣẹ akanṣe fun github
Bẹrẹ awọn idile oyin 3 ni awọn hives ti eto Palivoda (tabi awọn iwo ni awọn eniyan)
Ṣafikun “awọn buns” - wiwọn ọriniinitutu, iwọn otutu, ati pataki julọ - itupalẹ ariwo ti awọn oyin.
