The Professional 900MHz wireless temperature sensors use an external thermistor probe with a 6' cable 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.  The sensor is powered by 2 AA batteries for extra long life and the new flanged housing allows for easy mounting to various surfaces.
