This wireless water level indicator circuit will inform about the level of water. The maximum range of the circuit is upto 100 meters. It can be used any where to get alert about the required water level. The circuit is portable and wireless and free from the hassle of wiring. It can be used to get alert about the water level of water tanks, pools etc.
Step 1: RF Module
This project is using a ready made low cost RF module which can be easily purchased from your local electronic store or from a reputable online store.
Step 2: Transmitter Section
This is the transmitter section circuit, it is using a 555 timer IC, a BC337 transistor, transmitter part of the RF module and few other discrete components.
