Tank level + arduino + scada

Today we install a new on-line level sensor for one of our tank. Hardware involve are ultrasonic sensor, arduino uno, ethernet shield and 3g modem.

Picture above show staff installing the arduino board beside the tank which are connected to the ultrasonic sensor in the tank.

This is how we construct the system, very simple. The arduno board will send the data to modem which then will send to mysql sever.
