The LDSBus 4in1 sensor consists of 4 sensors in a compact low-profile design. Temperature, humidity, Passive Infra-Red (PIR) based motion detection and ambient light measurement sensors are incorporated in this multi-sensor device.

The device is available in two versions: a flush mounted design (for use on ceilings) and a swivel mounting design (for use on walls).

It works with the BRTSys PanL Smart Living, IoTPortal and LDSBus Hosts.
