The digital liquid level sensor has a plastic housing, which has an infrared (IR) LED and a matching phototransistor. When outdoors, infrared light is reflected back to the sensor. When the sensor head is immersed in the liquid, the infrared light will escape and the transistor will turn off. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is not sensitive to ambient light, is not affected by foam in the air, and is not affected by small bubbles in the liquid.

The micro controller-friendly logic level output is push-pull, absorbing and delivering up to 15 mA from a supply voltage range of 5.0 to 24 VDC - so you can even use it to directly control a transistor or even a small relay. Note that they are very sensitive and any liquid on the sensor (such as droplets on the surface) can trigger it.

Chemically resistant polysulfone housing materials - the standard choice for most applications - for external sensor mounting and use in the standard operating temperature range (-25 to 80 ° C).
