Non-contact Liquid Level Sensor (Open Collector Output)
$19.95  
4 pc(s)
This non-contact liquid level sensor can be triggered when the liquid level fall below the sensor attached to the outside surface of a non-metal container. Unlike traditional liquid level sensors, it does not need to be immersed into liquid. So, in this way, liquid will not be contaminated...

Water Sensor - Large
$2.50  
2 pc(s)
This water sensor is designed to detect water, which can be used to sense water level and leakage. It works by using exposed copper traces to detect the presence of water droplets. The sensor board has a sensing area of 47 x 36mm. The on-board potentiometer is used to set the threshold for...

Water Sensor - Small
$2.10  
4 pc(s)
This Water Sensor is designed for water detection, which can be used in sensing the water level and leakage. This sensor works by having a series of exposed copper traces which will turn on the transistor when water droplets shot the copper traces. This sensor works with the digital I/O...
