The XYC-WB-DC is a 5.8GHz microwave radar motion sensor module with a 3.3V to 20V DC input, consuming less than 3mA. It features a 360° detection angle, 6-9m range (default 7m), and a 1-120s delay (default 30s). Designed for motion detection through thin walls, it’s ideal for lighting control in high-ceiling spaces but may face interference issues.
| Operating frequency: | 5.8GHz |
|---|---|
| Input voltage: | 3.3V-20V DC |
| Power consumption: | ≤3mA |
| Detection angle: | 360° |
| Detection range: | 6-9m (default 7m) |
| Delay time: | 1-120s (default 30s) |
| Sender power: | ≤2mW |
| Operating temperature: | -20°C to +80°C |
| Pin | Function | Arduino Uno |
|---|---|---|
| OUT | Data output (=detection result) | Digital Pin (e.g. D4) |
| GND | Ground/0V | GND |
| VCC | Supply voltage | 5V (or 3V3) |
The setup is connecting the sensor module with a digital input to get the measured data. A LED shows the presence of human motion by lighting.
