The 8 Best Contact Sensors (2023 reviews)

The yolink contact sensor is specially designed for your daily purpose and has plenty of most useful features. This is a water sensor that has contacts on the top and bottom and sends an alert if it senses any water. It is nice to know when you have a water leak and not find out days or months later through soggy walls or ruined wood floors. This is a scant slip of paper with very small hard to read colored print. The device detects water quickly and accurately. The height or level adjustment is above from any splashing and normal operation of the sump pump.

The LoRa app shows the LoRa signal strength for each sensor as a signal power level in dBm. This will detect small leaks as long as the water leak gets to the sensor.

Inexpensive and effective protection for your house
Great reliable system with long range wireless connectivity
Installation is easy and the yolink app works very well
