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: $24.30
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, 314 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

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.
< Specification

Passive Infrared Sensor
Operating voltage DC: 12V
Load current : 3A

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.

Features:

  • Operating voltage: DC5V-25V Load current ≤3A
  • Detecting range ≤ 110 degrees cone angle
  • Delay time: default setting : 5-25s (2~280 Secondsadjustable)
  • Sensitivity= sensor distance : 4M-7M (10cm-7M adjustable) Please Note: DO NOT adjust the sensitivity to the minimum value, in this condition, this switch will not detect any movement and won't turn on the light strip.
  • Widely used on the Motion-activated lighting, LED strips Security System, automatic sensory device and more.

3. the object approaches, there is a perceived

4. traffic control;

5. security, industrial control;

6. artificial intelligence, and research

The basic working principle:

(1) using IO port TRIG trigger location, to the high level signal of at least 10us;

(2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;

(3) a signal return, a high level is output through the IO port ECHO, the time duration of the high level is

ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;

This module uses the simple method, a control port with a 10US above high level, can wait for high level

output at the receiving port. An output can drive the timer, when this port is low can read the timer value,

this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve

the measurement of the value of your mobile.
