D203B is a sensor that detects infrared radiation by using the characteristics of spontaneous polarization of materials changing with temperature. It adopts dual-sensitive element design to suppress the interference caused by changes in ambient temperature and improve the working stability of the sensor. This product is widely used, such as smart toys, automatic light switches, induction doors, etc., especially suitable for smart toy applications.
Product Features:
- Analog signal output
- Sensing Distance: 10M(lens SB-F-02), different lens selection for different distances

Notes:
1: The sensor needs to be used with a Fresnel lens to achieve the ideal sensing angle and sensing distance.
2: The sensing distance of the sensor is directly related to the ambient temperature and humidity, the temperature and moving direction of the acquisition target, the Fresnel lens, and the magnification setting. Please consider it comprehensively when using it.
