Wireless Water Temperature Sensor


Monnit's wireless water temperature sensor can collect temperature data of water or other non-combustible liquids using a sealed NTC thermistor with 3 foot lead wires. Powered by a single CR2032 coin cell battery and optimized for long life (approx. 1-2 years with normal use). User customization allows you to set the frequency of readings and thresholds that will trigger text or email alerts from the system.
