Energy is nowadays conserved by using Presence Sensors in residential and industrial applications. These are slightly different from Motion Sensors in that, they detect human presence instead of motion. They form an integral component of automation systems in homes and use various protocols like KNX, Modbus and Lonworks. Vacker UAE supplies various models of Presence Sensors such as ceiling mounted, wall-mounted, etc. in regions or areas such as Dubai, Abu Dhabi, Ras al Khaimah, Umm al Quwain, Sharjah and Fujairah.
