The Monnit Wi-Fi Low Temperature Sensor uses an RTD to accurately measure temperatures from -200°C to +162°C (-328°F to +325°F). Perfect for low temperature critical applications such as freezers and coolers. An integrated 802.11 b/G radio allows the sensor to workwith any existing Wi-Fi network. Monnit Wi-Fi sensors can be easily programmed with your Wi-Fi network's WEP or WPA(2) security via the free MoWi Setup Utility (PC application) and a MoWi USB programming cable.
Principle of Operation
The Monnit Wi-Fi LowTemperature Sensor outputs the ambient temperature in degrees Celsius or Fahrenheit. It is programmed to sleep for a user-given time interval (heartbeat)and then wake up,power up the RTD sensor and wait for it to stabilize then mathematically compute the temperature and transmit the data to iMonnit.
