This is a very simple liquid detector that use a relay to open an evacuation van. You can use it for water or any liquid that conduct electricity. Use any PNP transistor that can stand the relay ...

The CAP-100 Series capacitive liquid-level sensors provide accurate level sensing through the walls of plastic, glass, and fiberglass bottles. The sensors are suitable for medical applications such as ...

A new self-powered water sensor uses wave energy to monitor pollutants like heavy metals, microplastics, and pesticides - no battery needed. The innovation integrates two core components. First, a ...

Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...
