How To Choose An Infrared Product

The main consideration of using single, double and quad beam sensors is the detection distance. Usually, using indoor is no climatic factor so you can choose a single beam infrared sensor.
For outdoor use, we will suggest you choose double or quad beam sensors to fully ensure the high reliabilities of detection distance.
Single beam sensor: ~15 meters (indoor)
Double beam sensor: ~150 meters (outdoor)
Quad beam sensor: ~250 meters (outdoor)
