Automatic plant watering system using AVR(Atmega16) Microcontroller




Primitive irrigation systems possess many drawbacks as it fails to conserve water and human energy. So introducing Automation in it can help us to overcome these drawbacks and pave way to conserve water. This can be done with a simple Soil moisture sensor and a Microcontroller, AVR in our case. You can try out this system to automate watering the plants in your home at affordable cost.

SOIL MOISTURE SENSOR:

The Soil moisture sensor plays a crucial factor here. There are several ways to measure the moisture of the soil. We are going to measure the moisture level by the conductivity property of the moist soil. We all know that the moist soil conducts electricity better than the dry one. And the impedence level of the dry soil is higher than the moist one
