In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

But like I said, it's a cool project. I've thought about building an ultrasonic water level sensor, connected to an ESP32 or Pi Zero to report water levels to ...

The use of a microcontroller and ultrasonic rangefinder (like this tank level indicator from a February links post) would be overkill. No, [Donald] boiled down the electronics to a homemade switch ...

Nirchhari, the sensor for remote monitoring of water level, is operational at Peppara and Aruvikkara dams for the past three months. Originally developed to check level of sewage in sewer lines ...
