Quick Overview

authorized_reseller_badge_1
Monnit wireless temperature sensors use a thermistor to accurately measure temperatures. These sensors are perfect for monitoring ambient temperatures around the sensors physical location. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts via SMS text and/or email.

NIST certified product is available on leaded temperature sensors (select a lead length in order to see available certifications).

  • Accurate to +/- 1°C (1.8°F)
  • Available with an external temperature probe
