433mhz Radio Frequency PIR Motion Detect Sensor

*This is just sensor itself, need to use with other product, not working alone.
*This is sensor, no sound

This is to use with the alarm system we selling, don’t simply buy if you not sure, might not able to use for other system. Ask before order.

Product Features:
This infrared detector uses a micro-processing chip, high intelligence, high sensitivity, effectively distinguishes interference signals and human body movement signals, and resists false alarms. When an intruder passes through the detection area, the detector will automatically detect the movement of the human body in the area. If there is dynamic movement, it sends an alarm signal to the control host.

To avoid the false alarm, please pay attention to the following points for installing the motion detector:

1. Do not face the glass door/window.
2. Do not face the big object which is easy to swing.
3. Do not face the cold and heat air vent or cold and heat source, or anything rapidly change temperature.
4. Do not install near to high power appliances or any devices producing electromagnetic field.
