|TOPGREENER Motion Detector Light Switch, In Wall Sensor Switch, Occupancy Sensor Switch 500W LED CFL 1/8HP, Wall Plates Included, Neutral Wire Required, TDOS5, White, 2 Pack
Lowest new price: $30.38
List price: $30.38
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

2. obstacle avoidance, automatic control;
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.
