The Wireless Open/Closed Sensor can be used to detect when a door or window is opened and closed using a magnetic switch. • Detects when a door or window is accessed • Uses magnetic detection switch The Wireless Open/Closed Sensor uses an external magnetic switch to detect the presence or removal of a trigger magnet. When the sensor detects that the magnet is removed or returned it sends the information to the Sense IoT Online Sensor Monitoring and Notification System. The data is then stored in the online system and can be reviewed and exported as a data sheet or graph. Notification alerts can be set up through the online system to alert the user when a magnetic source is present or not with the ability to only notify within time of day parameters.
