About This

  • MANY APPLICATIONS! Sump pump alarm, AC condensate pan overflow alarm, runaway toilet/jammed flapper, internal toilet leak alarm, fish tank, pond, fountain, rainwater drum/tank, cistern, water storage tank high or low level detector
  • SPEND LESS, GET MORE! YoLink smart sensors are not only economical but they are part of a growing family of products compatible with your Water Level Monitoring Sensor. Shut off or turn on water on high or low level detection, turn pumps on/off, activate sirens and lights. Automatically.
  • WIRE LESS! The sensor is wireless and battery-powered, with LoRa-based extreme long-range wireless (up to 2,034 feet open-air!), so you can put your sensor where WiFi and older RF technologies can't go. No cables, conduit, raceway, trenching, or electrician required!
  • EASY DIY INSTALLATION with our innovative pendant-mount style float switch. Simply hang or suspend the float switch into the monitoring tank or container. The float switch's stainless steel washers provide ballast for stability against wave action, and also provide edge/sidewall protection. Tie wraps and tie wrap mount included.
  • KNOW NOW! This is a smart device with a full-featured app. Beware of products that require you be in earshot of the alarm. Types of notifications available to you include: app push notifications, email, SMS, siren or lighting activation, SpeakerHub sound or spoken messages. Each account receives 5 SMS per month per device, plus 5, free. YoLink Siren, Switch, Plug, Relay or SpeakerHub purchased separately.
  • ALARMING! The sensor has a built-in 105dB sounder, for local, indoor alarms. Or, add an optional remote Siren Alarm or other YoLink alarm product. Search B0887SMPKK for the Siren Alarm.
  • Looking for water depth monitoring? Our new Water Depth Sensor includes a water pressure sensor probe, capable of measuring water depths up to 16 feet (data reported in centimeters deep). Search B0C5QX3HHQ. Looking for the original Water Level Monitoring Sensor with probe? See the Water Leak Sensor 3, for applications not practical for a float switch, such as for washing machine water drain pipe backup detection. Search B08T8X4XWN
  • Looking for the optional ruggedized wall-mount bracket? The optional bracket provides the sensor with additional protection against impact, casual tampering and cord removal. Search B0C4PFTFM2
  • Compatible with Alexa, IFTTT and Home Assistant.
  • YoLink Hub is REQUIRED! This device will not operate without one of our hubs, not included. We recommend SpeakerHub, our talking, custom tone & sound, hub. Please search B09FSS95G9 for the SpeakerHub, or B07TQLKQLJ for the original Hub.
