Monnit wireless water temperature sensor use a 3 foot external water sealed sensor probe to measure temperatures in water or non-combustible liquids. Perfect for monitoring temperatures in water storage tanks, pools, aquariums and natural wet-life environments. User customization allows you to set the frequency of readings and the ability to set conditions for text and/or email notifications from the system.

The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
