Solar Motion Sensor Light Circuit

The solar panel that sits on top.

Solar motion sensor light circuit.

A solar motion sensor light usually features a metal frame and is typically positioned so that it can receive maximum solar power. Ollivage solar lights outdoor motion sensor security lights solar wall lights with dual head spotlights 30 led waterproof 360 adjustable solar motion lights outdoor for garden garage patio 1 pack. 2 pir motion sensor. The solar security light.

The light is designed to be mounted on a wall that has direct visibility to the sky above it. A simple circuit controlled by two major things. When the pir sensor distinguishes anybody in its range. The circuit is totally automatic.

4 2 out of 5 stars 1 758. 1 x 1 2 volt battery at least 1 5 volt solar cell in full sun. The solar panel sits at the top perpendicular to the wall that the unit is mounted onto. This can be done on perfboard too.

It will charge a 6v 1 2ah lead acid battery in the day time within the sight of daylight and enact the lights after sunset. Like any solar energy device solar motion sensor lights work by harvesting the sun s energy to either power a light immediately or to store the energy for future use. The light itself sits at a slight angle while the motion sensor and button sit at a much steeper angle. 2 x 1 2 volt batteries at least 3 volt solar cell in full sun.

So batteries and the circuit dictate the solar cell size there are some of these lights with pr sensors that use a 3 7 volt battery and a solar cell of 4 5 volts.
