Applications

  • Sensory Switch

  • The PIR motion sensor adopts high-performance infrared detector. As long as human cross through its detection range, the infrared switch generates an electrical signals.

 

FAQ

1.How long do motion sensor lights stay on?

Most people set their motion detection lights so they will stay on for about one to two minutes.

 

2 .Do motion sensors save electricity?

Motion sensing switches do have some &ldquo;phantom&rdquo; energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.
