We can provide not only the best ODM and OEM processing but also our automatic testing chamber for you to test your PIR sensor products.

With the improving our living quality, the industry of home intelligence become more popular. The application of PIR sensors can provide a long-term standby because of its low power consuming (a few microamperes). When the sensor detects the human body, the device will turn on automatically. This function can be used on such as lighting, Bluetooth, camera, wifi......and so on. However, a PIR sensor receives the infrared light emitted from the human body, and that´s where Fresnel lens works. For different functions on different products, we can provide long distances (1-40 m) and wide angle (0-180 degrees) to cope with the environments and to fit your designs. In the smart home applications, to match the beautiful surface of your products, Fresnel lens must be a flat or slightly curved, and the focal length must be short (10mm or less), so the lens design and manufacturing capabilities have become a great challenge!

Our company focuses on “satisfying the customer, exploiting& innovating”, and keep innovating new technology and improving products´ quality to provide the best service for our clients.
