# 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*)



## Topics



* **Poulailler/Perchoir/Temperature** : as the name said

* **Poulailler/Perchoir/Humidite** : as the name said



* **Poulailler/Eau/Niveau** : Suffisant / Vide



* **Poulailler/Luminosite** : Jour / Nuit



* **Poulailler/Alim** : Power supply

* **Poulailler/Memoire** : available memory

* **Poulailler/Reseau** : Network we are connected to

* **Poulailler/Reseau/Change** : when we switch to another network

* **Poulailler/Wifi** : time to connect to the WiFi network

* **Poulailler/MQTT** : reconnect duration



* **Poulailler/Error** : Error messages

* **Poulailler/Message** : various messages, output, ...

* **Poulailler/Command** : MQTT commands topic ...



* **SondePiscine[-Dev]/TempPiscine** : pool's temperature



## 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
