Components relay traffic : Using infrared motion sensor HC-SR501 and single-channel relay module You can create a device , which can be called "Relay traffic" and use in intruder alarm systems as well as systems of "smart home".

How it works relay traffic :

The lens, which is installed in the motion sensor , divides the room for a certain number of sectors, fixes the temperature in the room and directly in each sector. In case of contact person in a certain square IR sensor , the temperature changes in this sector as the temperature is usually higher than the temperature of human indoors. In turn, IR Motion Sensor processes this information and sends a signal to the relay. When triggered, IR motion sensor , relay opens the circuit loop power supply.

Areas of use relay traffic :

  • Lighting various premises, ie automatic on / off lighting in the hallways, warehouses, apartments, houses, and in the courts and on the streets.  
  • alert the homeowner about the arrival of guests. In this case, the sensor should be directed to the gate of the fence or the space around it.
  • The security alarm for economic yard, garage, farm, office, apartment. In this case, the relay closes the circuit power powerful sound of the siren.

The company has GreenChip offers you to buy relay traffic low low price!

You can also buy separately infrared motion detector HC-SR501 and 1-channel relay module .
