Motion Detector Light Switch in Wall Sensor Switch, Occupancy Sensor Switch 500W LED CFL 1/8HP, Wall Plates Included, Neutral Wire Required, White

Motion Detector Light Switch in Wall Sensor Switch, Occupancy Sensor Switch 500W LED CFL 1/8HP, Wall Plates Included, Neutral Wire Required, White Lowest new price: $30.38
Lowest used price: $19.55
List price: $30.38
Brand: TOPGREENER
Model: TDOS5-W-2PCS

TOPGREENER TDOS5 combines occupancy and vacancy sensor into one light switch for energy efficiency, security and convenience, while in compliance with the 2011 NEC Code. When no motion is detected within delay time you set, the connected load will turn off automatically. This light sensor switch detects fine motion. Energy Efficiency: The motion sensor light switch automatically turns ON/OFF based on room occupancy, avoiding the waste of energy from leaving the lights/motors on when nobody is in the room, including bathroom, closet, hallway, and office. Running the TDOS5 consumes little power, est. cost only $1 a year. The sensor light switch automatically turns the light on to avoid blind-searching and tripping when entering a dark room. Enhances safety and security: Occupancy sensor switch can also effectively deter thieves and allow security cameras to capture clear footage. To conserve energy and prevent lights from automatically turning on during day time, all you need to do is adjust the light level knob to change the light sensitivity of the sensor. Operating modes: • Occupancy Mode: Light switch sensor will automatically turn on the lights when you enter a room and automatically turn off after the room is vacant, making it especially convenient when entering a room with your hands full. Perfect for many applications such as the kitchen, laundry room, garage, restroom, office, closet, etc. • Vacancy Mode: Requires manually turning the light on and automatically turns the light off when the room is vacant. Vacancy mode is used in rooms that do not need the lights to automatically turn on, such as bedrooms and media rooms. Vacancy mode provides the most energy savings as it ensures that the lights will automatically turn off when the room is no longer occupied. NEUTRAL WIRE REQUIRED

Features:

  • Automatically detects motion from passive infrared sensors to turn lights on and off based on room occupancy and vacancy
  • Sensor switch with passive infrared detection (PIR): detects infrared to reduce false triggers from unwanted movements
  • Variable time delay from 15 sec (Test) to 30 min. Adjustable range
  • Auto ON/OFF, Manual ON/Auto OFF; After install and turning on circuit breaker, allow about 2 minutes to warm up before operating the device
  • NEUTRAL WIRE REQUIRED, 1,200 square feet coverage, High range motion detector with 180 Degree View; 500W Incandescent, Halogen, Fluorescent, LED, CFL, Works with all bulb types. Single Pole Only. 2 wall plates included (8831-W)

Description

PIR(Passive infrared) Motion sensor is pyroelectric device can detect human movement by detecting Infrared ray emitted by human body. Operating voltage is 5~25VDC, and output voltage is equal to input voltage. High sensitivity, Easy to install.
Automatic Induction

When people enter into the sensing range, Motion sensor will output a voltage equal to input voltage, after the delay time, it will output 0V; During the delay time if motion detected, the delay time will reset, and start a new delay time.
Application

Widely used on the Motion-activated lighting, LED strips Security System, automatic sensory device and more.

Note:

1. The PIR Sensor requires a 'warm-up' time in order to function properly, about 10 s to1 min, depending on the delay time; during this time, the signal triggered by the module is not stable, after one minute, it will be ready.
2. Don't expose the Sensor Switch to direct sun light /lighting, big wind, or placing near to a heater or air condition.
3. Don't fix the item at a place where there are obstructing material (eg. Glass, dense clothes) which IR cannot get though.
4. Don't fix the motion sensor switch in strong shock or vibration environment.
