The LIS-2 Infrared Sensor Switch detects the presence of an object by determining whether the emitted infrared signal is reflected back, triggering the relay to switch. The reference sensing distance is approximately 12 cm (the actual distance may vary depending on the material of the reflective object). It can be used in applications such as sensor faucets and automatic hand dryers.
