The Monnit Wi-Fi Infrared Motion Sensor uses an infrared sensor to accurately detect movements made by people or large animals within 16.4 ft (5 m) range. 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(2) security via the free MoWi Setup Utility (PC application) and a MoWi USB programming cable.
Principle of Operation
The Monnit Wi-Fi Infrared Motion Sensor detects motion and movement using infrared technology. When the sensor detects movement it communicates with the iMonnit Online Sensor Monitoring and Notification System. iMonnit stores all data in the online system where the datacan be reviewed and exported as a data sheet or graph. Notifications can be set up through the online system to alert the user when motion has been detected.
The X-Y cross-sectional diagram shows the detection area.
The differences in the detection zone patterns are indicative of the projections of the 16 lenses with single focal point and with five optical axes. An object whose temperature differs from the background temperature and which crosses inside the detection zone will be detected.
