You can also control your lighting with movement sensors. Due to the fact that the light turns on when the owners arrive and turns off when they leave, the electricity savings are considerable. Motion sensors to buy - this is not a luxury, it is a long-term savings, you will not pay too much for electricity. Given today's rates, that's something to think about, right? Infrared and microwave are the most popular. Each type of device has its own advantages and disadvantages. For example, infrared controls respond not only to motion, but also to heat levels. They are ideal in lighting home interiors, they are convenient to use in places where you are not there for a long time (elevator, corridor, basement, garage). But where there are these motion sensors, it is better not to hang curtains that can sway from the wind blowing from the window, and not to turn on the fans.
Microwave sensors work by catching emission of high-frequency electromagnetic waves and detecting reflections from objects. They are small and easily fit into hard-to-reach places. Compared to infrared devices, they do not need powerful lamps and can detect people through windows.
