![]() Receiver Module is made of with HT12D decoder and ASK RF receiver. This circuit is placed near the Water Tank and connected to the tank as show in the figure below. For more details about this transmitter, please read the article Wireless RF Transmitter and Receiver using ASK RF Module. This circuit can be drive using 9V battery. Level Sensor module is made of with HT12E encoder and ASK (Amplitude Shift Keying) RF transmitter. Circuit Diagram:ΔΆ.Water Level Sensing Section ASK RF Transmitter Controller module requires +5v and +12v supply. Receiver module requires +5V power supply. Power Supply section provides required supply for Receiver and Controlling modules. ![]() Receiver Section is connected to the Controlling Section, which process the received information and produces visual, sound indications and controls the operation of the motor whenever required. The Water Level Sensing Section senses the level of water in the tank and sends it (wireless) to the Receiver Section. Here is a simple, versatile project which indicates the level of water and automatically controls it by using PIC Microcontroller.
