Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

A portable sensor for rapid lead detection in drinking water empowers communities to monitor contamination effectively and ...

The indicator on senor near the water level ... The capacitance detected will change depending on whether the liquid is near the sensor or not. This change is then converted into a digital high or low ...

As the world has become increasingly concerned with environmental conservation, efficient industrial processes and effective management of water resources, the importance of water level measurement ..

In level monitoring ... between multiple sensors for multi-channel measurements without the danger of a short circuit. The extremely low noise sensor cable provides an impermeable electrical shield.

Commenters told him that the best fluid level sensor was a hacked blood ... measure fluid levels including ultrasonics, floats, capacitive sensors, and, of course, math.

The results confirm that the proposed circuit is well suited for sensors, such as capacitive humidity sensors, water level detection sensors, and fingerprint sensors.

In a way, the magic of a soil moisture sensor ... two PCB traces that are near one another. Their capacitance — and therefore their charging rate — changes in response to how much water ...
