My chickens on TTN

Greetings,
I’d like to introduce my hen house project, a solar-powered hen house controller with LoraWan connectivity.

Key features are:

  • Runs on an Adafruit Feather 32u4 board (ATmega32u4) equiped with a LoRa Radio Module
  • Entrance guillotine-style door is motorized. Two reed end-switches detect the door open/close positions
  • UP/DOWN interface buttons to manually force door opening/closing
  • Door automatically opens/closes at sunrise and sunset (function of an ambient light threshold)
  • Measures individual temperatures in 4 nesting boxes (aim is to detect when a new egg was layed) + computes an average
  • Runs on a 3.7V 4400mAh Lithium Ion Battery Pack and a 6V, 1W solar panel
  • Goes to DeepSleep until UP/DOWN buttons are pressed
  • Broadcasts every few minutes the systems’ metrics (temperatures, ambient light level, door position, battery level and charging status), received by home automation system in JSON format via MQTT broker

Magnificent, make sure to paint it all or the chip-board will de-laminate though :wink:

Wife and kids wanted to keep the raw color so I varnished it :wink:
