This non - contact liquid level switch is a game - changer. It triggers when the liquid level in a non - metal container drops below the sensor attached to the container's outer surface. Unlike old - fashioned liquid level sensors, it doesn't need to be submerged in the liquid. This means no liquid contamination and a longer sensor lifespan as there's no direct contact with the liquid. The sensor is both sensitive and stable, with an output current of up to 100mA, which can directly drive a relay. You can attach it to your water machine to monitor its status or to your cup for a water - drinking reminder. Specifications include a +5V power supply, a 25µA working current, a working temperature range of - 25~125°C, and it can detect through walls 1 - 13mm thick. You'll get a manual, product WIKI, and one non - contact liquid level switch with a sensor cable.
Using this non - contact liquid level switch is easy. First, find a non - metal container where you want to monitor the liquid level. Attach the sensor to the outside surface of the container. Make sure it's firmly in place. Connect the switch to a +5V power supply. Once it's powered on, it will start monitoring the liquid level. When the liquid drops below the sensor level, it will trigger. You can use this to drive a relay or set up alerts. For example, attach it to your water machine to know when it's running low on water or to your cup to remind you to drink. As for maintenance, keep the sensor clean and dry. Avoid exposing it to extreme temperatures outside the - 25~125°C range. If you notice any issues, refer to the manual or product WIKI for troubleshooting.
