Product details
This non-contact liquid level switch can be triggered when the liquid level falls 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 in liquid. So, in this way, the liquid will not be contaminated and the life of the sensor will not be reduced so fast because of the contact between liquid and sensors.
The sensor is very sensitive and stable, and the output current is up to 100mA which can directly drive a relay.
You can use this switch to monitor the condition of your water machine or make a water-drinking reminder by attaching it to the surface of your cup.
