This is one of my coolest undergraduate projects with my friends for the project exhibition of CENNOVATION 2013 which was held at the premise of Islamic University of Technology, Gazipur, Bangladesh. In the project, I used a solenoid valve which was controlled by an IR sensor pair of transmitter and receiver. The control circuits included an avr 8-bit microcontroller (Atmega8) and a relay for triggering the AC solenoid valve.
