Vacker Nigeria also supplies presence sensors to its major cities like: Lagos, Abuja, Kaduna, Port Harcourt, Ibadan, Kano, etc. We supply these sensors especially to the industrial and residential areas in order to conserve energy. Various manufacturers have various models of these sensors to offer. Some sensors are wall mounted; some are ceiling mounted and many more. Presence sensors are most of the times confused with the Motion Sensors. But we should know that these have distinct operating principles. These sensors make an integral part of our home automation system and can be operated via dedicated modus operandi as: Modbus, KNX, Lonworks etc.
