PIR Sensor with Pull Cord Switch

A NEGAVEEZ PIR Motion Sensor offers security and convenience in the areas that they cover. PIR sensor is an intelligent device which detects IR Rays emitted by Human Body and controls the ON-OFF operation of electrical loads. Electrical Loads can be Lights, Fans, Air Conditioning Units 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. Sometimes one requires the Lights/Electrical Loads to be Continuously ON (Ex: Festive Season, Evening Time, Serious Office Work). There is a mode settable by a Pull Cord Switch to put the Electrical Load in Continuous ON Mode or PIR Sensing Mode, thus offering Comfort as well as energy efficient automation.
