Sensing parameters
- Working frequency
- 24G Hz -24.25G Hz, IsM frequency band
- Transmit power
- 5mW Max.
- Detection Area
- RS485 protocol adjustment: 0-4m (adjust the step in 0.5m units)
- Delay setting (Hold Time)
- 3s-7200s Note: To implement the presence detection function, a delay setting of ≥15s is required
- Illumination setting (Daylight)
- When the change in ambient illumination meets the preset illumination difference, the sensor immediately reports the ambient illumination value. Sudden change value (10-100lux) can be set through the serial port.
- Ambient light measurement range
- 0-1200Lux (the product is installed at a height of 3m, and the illumination value of the ground directly below the product is collected)
- Detection range (100% sensitivity, radius)
- Movement/micromotion/existence (3m high): 3.5±0.5m (based on indoor open 41㎡ space test, the sensing distance may fluctuate slightly in different environments)
