piFarm is a personal indoor farm with GUI running on raspberry pi, written in C.

• very simple GUI interface
• manual mode or auto program mode
• temperature / humidity monitoring
• simply configurable by configuration file

• 1 Raspberry pi computer
• 1 cheap 16 relay module
• 1 bme280 i2c module
• at least 3 DC voltage regulator modules (3.3v, 5v, 12v)
• a suitable power supply
• desired actuators (led strip, water pump, fan, heater ... )
• [optional] touchscreen

Important note : Raspberry pi GPIO logic output is 3.3V. My relay board has 5V logic and relays are powered by a 12V input. Relay board logic is indirectly powered by a 5V regulator connected to the 12V input. In order to make it work with the raspberry pi, i had to unsolder the 5V regulator onbord, and power logic via an extern 3.3 DC source.

• Raspbian distro (with desktop)
