Diffuse infrared sensors emit infrared light and receive echoes reflected from objects, judging the presence and approximate distance of objects based on reflection intensity, without needing a paired reflector, making installation extremely simple.
The KE200 from Shenzhen Xingkechuang Technology Co., Ltd. is optimized for outdoor and strong-light environments, featuring multi-layer optical filtering and sunlight-resistance algorithms, ensuring it does not saturate even under windows, balconies, or water tank covers. In IoT scenarios, it often acts as an "assistant eye":
Smart trash cans: Detect hand proximity → open lid;
Water purifiers: Detect cup placement → dispense water;
Liquid level double insurance: Provide "overflow object proximity" judgment next to capacitive level sensors.
Xingkechuang KE200 supports both switching and analog outputs, connecting directly to IoT gateways. It saves computing power compared to pure vision solutions and is cheaper than ultrasonic sensors, making it the for lightweight IoT terminals.
