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.
