Poulailler

My chicken coop automation.

Automatisation de mon poulailler. Ce projet est majoritairement en anglais, non pas pour faire le mec qui s'y croit, mais simplement pour pouvoir partager sur les forums internationaux.

Goals

Due to several issues with the chicken coop itself I had to manage, I missed my deadline and had to buy a commercial door automation. Consequently, despite it was close to be finished, I gave up with v1 which is now stalling and this v2's goals are simpler :

  • temperature and humidity monitoring
  • check the door is open at sunset and open at sunrise
  • ensure there is remaining water
  • still connected to my home automation : expose critical figures on my dashboards, raise alarm in case of trouble ...

ESP8266 GPIOs

The material is recycled from v1: some parts of the material could have been simplified and some GPIOs are currently unused.

  • ADC : power supply monitoring (internal)
  • GPIO0 : enable aux power (out / low)
  • GPIO2 : 1-wire
  • GPIO4 : Water warming (unused)
  • GPIO15 : unused Door open (high depend on GPIO13)
  • GPIO013 : door is open (In / internal pullup / low)
  • GPIO012 : door is closed (In / internal pullup / low)
  • GPIO014 : roof is closed (In / internal pullup / low)
  • GPIO5 : DHT22

DS2413 PIOs

  • PIO.A : sun light (low)
  • PIO.B : water low (low)

Hardware

  • MX1508 H-Bridge
  • 3a77553800000091 : DS2413 - Day light & water probes
  • 28ff8fbf711703c3 : DS18B20 - Pool temperature

Test Bat

ADC = 5v * 25.1 / (100 + 25.1) = 1.0032v I = 5 / 125.1K = ~ 40uA
