RF communication based Smart water level controller
Generally we forgot to switch off the water pump, it comes to our notice only when we have lost lot of water and burnt electricity. This project provides a smart solution for this problem. Low cost and efficient measurement and removal of cluttering of wires is one of the major requirements of this project. Reed switches are used as level sensors. They are placed at different height corresponding to different readings in an Acrylic tube. Floating magnet moves up and down in tube to switch on or off different reeds. No need to have ADC or even microcontroller at the transmitter side. It uses AT89c51microcontroller at receiver side, 434MHz transceiver.
