A motion sensor that has the ability to detect small changes in the environment caused, for example, by the movement of the human body. Its PET function allows it to detect movement at human height level and ignores movements closer to the ground so as not to be activated by a household pet. It operates on batteries and can be placed anywhere as it does not require a permanent connection to electricity. Offers you the ability to control it via Wi-Fi, Bluetooth, ZigBee, and RF (radio waves).
