Human Body Induction Module - RCWL-0516 (with Headers)

The RCWL - 0516 is an amazing device that uses radar Doppler technology. It's a special microwave induction module designed to detect moving objects. This fantastic microwave radar sensor module can sense inert objects as long as they have sufficient density, volume, and are in motion. It can even detect motion through various materials like glass, drywall, ceilings, and floors. However, the more shielding there is, the shorter the detection range will be. It's extremely sensitive, so you may need to filter the power supply. Features include an output power of 3.3V and a wide fan operating voltage from 4 - 28V. You can also find its schematic in the documents.

Using the RCWL - 0516 is quite easy. First, connect it to a power supply within the 4 - 28V range. Then, place it in the area where you want to detect motion. It can detect through materials like glass and drywall, but remember that more shielding will reduce its detection range. Since it's very sensitive, you might need to filter the power supply to get stable performance. As for maintenance, keep it clean and away from moisture. If you encounter any issues, check the schematic to troubleshoot.
