Water level detection telemetry circuit

Relevant key device information applied in this article: TWH9238B TWH9236B CD4028 CD4081 CD4069 CD4584 C304 water tank water level telemetry uses the water level detection electrode to digitally encode the water level changes through the digital circuit, and sends the code outward through the radio transmission circuit. After the receiving end demodulates the received signal through the radio receiving circuit, the code is restored through the decoding circuit and the decoding result is displayed through the display circuit.
