Sensors and camera

A project log for Autonomous watering system

This system decides how much water your plants need according to its sensors and internet weather stations and controls a pump to water them

The Raspberry Pi board has plenty of GPIO lines available for hooking up sensors such as DS18S20 1-wire temperature sensors:

I might also hook up a soil moisture sensor (measuring capacitance) in the future, even though we have more then enough weather data as it is.

The Pi camera has been a nifty addition to the system. We can now use it to monitor the plants and environment remotely!
