20200708· But today I decided to mount it on the ceiling and switch to batteries. What I have observed is that the motion OFF command is really slow to come in. I''ve configured the sensor''s "PIR time" to 10 seconds. The ON event comes in right away, but then the OFF event is not sent for a long time (still trying to figure out how long).

Do PIR lights work in daylight?

20200527· Likewise, people ask, do motion sensor lights work during the day? When paired with motion detectors, photocells keep lights off during daylight hours. They work as security lights in the evening, turning on when they sense motion after dusk. You can also adjust these fixtures to allow the motion sensors to work all day.. Secondly, how does a PIR light work?

CO₂ sensor vs. motion detector | Senseair

They behave much like a PIR but detect motion 360°. One of the big disadvantages of the microwave sensor is that it is too sensitive and might detect motions on the other side of a wall/medium that the radiation can penetrate. It could therefore potentially be triggered by unintended events, like movements outside a facility.
