MUHWA – PIR Fresnel Lens
Activate the first step of Smart Home Device
1. To fulfill the device’s longer standby periods, we can take the advantage of the low power consumption of the PIR sensor. After PIR module detects human body temperature, it can activate the device, including lighting, video recording, Bluetooth function, Wi-Fi function, and so on.
2. Through the professional optical design and the production process of Fresnel lens, the infrared light emitted by the human body is focused on the PIR sensor, which can realize various detection requirements of various distances and angles.
3. Infrared sensor lenses are special in smart home applications because they need to meet the needs of the product's appearance, the surface is curved, flat, or even irregular, and in the case of short focal length, lens design and manufacturing process are really challenging.
