Passive Infrared Sensor (PIR Sensor) Beacon S2


S2 Bluetooth Passive Infrared Sensor Beacon
KKM Bluetooth PIR sensor is a passive infrared sensor with Bluetooth 5.0 technology, it converts the infrared signal to current or voltage, and trigger the BLE advertisement.

It alert the App or send advertisement to gateway.
Accordingly, they are used to detect presence, occupancy, and count. 

● S2 Passive Infrared Sensor Beacon uses ultra low power consumption nRF52 series chipset and BLE 5.0 technology, as well as a energy saving PIR sensor.
● S2 PIR sensor beacon has 110 degree wide detection angle and 8-12 meters detection range.
● S2 Bluetooth PIR sensor can configure the monitoring period, avoid unwanted alert and activate the PIR sensor in specific period. 
● S2 PIR sensor beacon also has a very strong BLE signal.
● S2 PIR sensor is stylish designed, it can use for indoor location-based service, such as people counting, door open/close, security alarm and etc.
● We can also configure the parameter or customize the PIR sensor based on your need.
