Monnit Corporation introduces a low cost wireless temperature sensor along with nine other types of wireless sensors. The sensors currently use a USB receiver at the computer level to transmit all of the sensor data to your choice of either the MonnitSphere Online Monitoring Service or the MonnitSphere Local PC computer application. The sensor data is then checked against user defined thresholds to determine if a notification should be sent to the user via email or SMS text message.
- The sensors operate at 900MHz (25 Channels) and provide a reliable operating range of approximately 1000 feet depending on the environment.
- Powered by a Lithium Ion 3V battery the sensors have a lifespan of approximately 4 years when set to a heartbeat of 2 hours. (The sensors hold user defined threshold values and can be set to check against those value as often as desired, and will bypass heartbeat settings to communicate if and when thresholds have been met or exceeded.)
- The sensors have a small footprint (1 in. by 1 in.) and are ideal for embedded applications.
- The wireless temperature sensor is accurate to +/- 0.5°C (1°F) with an operating range of -40°C to +125°C.
Monnit Corporation provides both OEM and finished products along with the software for customizing the sensor parameters and storing the sensor data. Typical deployments include Hotel Management, Building Operations, Facilities Maintenance, HVAC Monitoring, Food Services and Property Management.
