Recessed Mounted PIR Sensor

A NEGAVEEZ PIR Occupancy Sensor offers security and convenience in the areas that they cover. Occupancy sensor is an intelligent device which detects IR Rays emitted by Human Being and controls the ON-OFF operation of electrical loads. Electrical Loads can be Lights, Fans, AC for Energy Saving Application or Siren, Buzzer, Feedback to Home Automation Controller along with Lights for Security Application. This highly sensitive Sensor Element detects human movement within its detection area and automatically turns the load ON. The Loads are kept ON till the Human Movement persists in the room. The Loads are turned OFF after preset time delay if no movement is detected within the set time It has an additional in built photo sensor (dusk to dawn sensor) which can set the sensor to turn ON artificial light only when the ambient light condition (LUX Level) drops below the set value. This reduces the large amount of energy wastage and helps in making the most energy efficient system along with security.
