Turn your LEDs on with Motion! Our motion sensor takes 3 volt - 12-volt input and can run up to 30 LEDs.
In tests, the round white sensor "ball" can detect motion up to 2 or sometimes even 3 feet away. The sensor keeps the lights on while there is motion. After motion stops, the lights remain on for up to 15 seconds. We found just being near the sensor was enough to keep the lights on until we walked away.
This is a great way to have your projects light up when you walk up to them or even walk by! And have your lights turn off automatically when you leave.
Model Train Enthusiasts: Use this sensor to detect your model train when it passes, to turn on a crossing gate signal further down the track. The sensor will turn on the crossing signal, then turn off 20-30 seconds later automatically when the train is no longer triggering it.
Dimensions: The sensor is
- 15mm Diameter
- 14mm High
There are 4 wires already attached to the motion sensor. 2 input wires to connect to your chosen power supply, and 2 wires to go out to your LEDs.
The longer wires on the Motion Sensor connect to the wires on your power supply. The shorter wires on the motion sensor connect to all of your LED wires. You can of course cut any of the wires, just remember the orientation from power to the sensor, from the sensor to your LEDs.
Why have a switch on the battery if the motion sensor is a switch?
The white switch is on/off so if it is left in the on-state it will not affect the motion sensing. The motion sensor will always turn on with motion. So the white on/off switch is a more permanent way to turn off your project if you need it.
