Check out the new water level sensor circuit. The simple water level indicator circuit presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead ...

What he ended up with was a water level sensor made from PVC pipe and a few other components. ... Farmers know how to hack and keep it simple. Toilet float or the TSC float switch. No “duino needed.

The basement water tank level sensor is another simple (1-point level) float switch, added as a dry-run protector. Hermetically sealed-in-glass reed switches located inside the stem are ...

Some years ago, we covered a simple water level monitoring using a Parallax Ping sensor, but back then the IoT and the ‘cloud’ weren’t nearly as fashionable. They also tested with infrared ...

The noninverting input (pin 2) is connected to sensor B through R1 for lower-level detection of the water. The open collector of the built-in transistor (pin 7) is connected to the +12-V terminal.

It will switch off only after the water drops below level A. Figure 2 illustrates the complete circuit. Using a rail-to-rail op amp for U2 allows for the application of a single 5-V power supply.

Dome angle, liquid characteristics and floor repellence combine to make the water sit in a ring around the edge if the sensor is level, and in a crescent around the walls if the sensor is anything ...

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 ...

My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 minutes; I have to do this less than once a month. But like I said, it's a cool project.
