About this item
- Widely used in anti-theft cameras, smart homes, security monitoring and other fields. Its flexible application scenarios and powerful functions make this module an ideal choice for modern smart homes and security systems.The module size is 36x17mm, the operating voltage is 3.3V, and it has an accurate sensing distance of 3-5 meters.
- Using a dedicated signal processing control chip RCWL-9196, it is a microwave sensing module that uses Doppler radar technology to detect the movement of objects. The module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle, and wide power supply voltage range.
- Installation Note: 1. There must be no metal obstruction in front of the sensing surface. 2. Reserve more than 1CM of space in front and behind the sensing surface. 3. The module is as parallel as possible to the plane of the installation carrier.
- 4. It is effective in a certain detection area. 5. The component side of the module is the positive sensing surface, and the reverse side is the negative sensing surface. The sensing effect of the negative sensing surface is slightly worse. 6. Microwave modules cannot be used on a large scale in the same area, otherwise there will be mutual interference, and the distance between individual bodies is greater than 1M.
- When a person or object enters the sensing area, the module will automatically start and control the switches of related equipment (such as lighting fixtures and anti-theft cameras) to achieve intelligent control. At the same time, it supports the delayed shutdown function to ensure that the equipment remains in working condition for a period of time after the person leaves, meeting actual needs.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
