The Monnit Wi-Fi Temperature Sensor uses a thermistor to accurately measure temperatures from -40°C to 85°C. An integrated 802.11 b/g radio allows the sensor to work with any existing Wi-Fi network. Monnit Wi-Fi sensors can be easily programmed with your Wi-Fi network's WEP or WPA security via the free MoWi Setup Utility (PC application) and a MoWi USB programming cable.
Principle of Operation
The Monnit Wi-Fi Temperature Sensor outputs the ambient temperature in degrees Fahrenheit or Celsius. It is programmed to sleep for a user-specified time interval (heartbeat) and then wakeup, send power to the NTC Thermistor, wait for the reading to stabilize, calculate the temperature and transmit the information to iMonnit. To stay within the abilities of the processor, the temperature is computed from a data table provided by the manufacturer. To reduce error, a variable resistor configuration is implemented over specified temperature ranges.
