Wireless water level indicator without microcontroller by circuityep.This is a simple wireless water level indicator using rf wireless technology. You will also get wireless water level indicator project report here.
What is wireless water level indicator
A simple water level indicator uses wire to transmit singnal from the stored water tank to the water level monitor circuit board. Its simple but you will need 5 seperate long wires and also you must drill holes on walls of house, which makes walls of your house looks ugly.
Inorder to avoid such problems we are making water level indicator as wireless.
Components Used
Transmitter Tx 433 module
Receiver Rx 433 module
HT 12E Ic
HT 12D Ic
Working :
The HT 12 E is a decoder Ic which has four inputs in general. We are giving 4 wires to these terminals for sensing water level with respect to ground.So a total of 5 wires is available to sense water.
While powering on the encoder activates signal and send the signal wirelessly to the decoder receiver module.
The HT 12D which is the decoder decodes the signal and outputs the led indication.
We also added a buzzer at the LED output which is connected in parallel to the overflow LED signal.A transistor is connected to drive the buzzer.The buzzer will sound if the LED overflow signal is on.
This is how wireless water level indicator works.
