Fully Automatic Water Level Controller using SRF04

Ultrasonic Range Finder SRF04:

The SRF04 is a superior quality ultrasonic ranger that is utilized in many robotic applications for simple detection of obstacles. It takes 10 microseconds to reach the trigger state. Once triggered, it will generate 8 pulses of ultrasound, at a frequency of 40 KHz and simultaneously raises its echo line to HIGH.

Once it receives the reflected signal or echo, it lowers the echo line to LOW. The width of the echo pulse, in this case, determines the depth or distance from which water levels can be measured.
