Light sensors mains powered by 230 V

230 В

— powered by a conventional household mains — an option used mainly in light sensors. Such devices are designed to switch the voltage of 230 V supplied to the lamps — it is quite logical to power the sensors themselves from the same 230 V. Occasionally, there are other types of sensors with a similar connection, sometimes of a rather original design — for example, gas sensors that are plugged into a socket when installed, or wireless motion detectors that are mounted in a lighting cartridge.
