8. TOPGREENER TDOS5-W Motion Sensor Light Switch, PIR Sensor Switch, Occupancy Sensor Light Switch, Motion Sensor Wall Switch, 500W 1/8HP, Neutral Wire Required, Single Pole, White
Feature
Sensor switch detects motion to automatically turn lights on and off based on the occupancy and vacancy in a roomMotion sensor switch uses a passive infrared (PIR) sensor to reduce false triggers from unwanted movements
Occupancy switch mode (Auto ON, Auto OFF) and vacancy switch mode (Manual ON, Auto OFF) allow you to customize the sensor according to your needs
Light switch sensor features adjustable settings. Variable time delay from 15 sec (Test) to 30 min. Adjustable range
NEUTRAL WIRE REQUIRED, 1,200 square feet coverage, 180 Degree View; 120VAC, 500W Incandescent, Halogen, Fluorescent, LED, CFL, Works with all bulb types. Single Pole Only. Wall plate included
Description
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 REQUIRED9.

Sensky BS010l Dc12v to 24v Mini Pir Motion Sensor Switch,occupancy Sensor SwitchDescription:
PIR(Passive infrared) Motion sensor is pyroelectric device can detect human movement by detecting Infrared ray emitted by human body.
Automatic Induction: When people enter into the range of induction, it 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.
widely used on the Motion-activated lighting, LED strips Security System, automatic sensory device and more.
Specifications :
Operating voltageDC12V
Load current3A
Delay timeDefault setting5-25s (2~280 Seconds adjustable)
Detecting range : About 110 degrees cone angle
Detecting distance: 4M-7M (10cm-7M adjustable)
Trigger way : continuous triggering
Blockade time: 0 seconds
size: 48*25*14 mm
Attention:
1.Don't exposed to direct sun light or lighting, big wind, near a heater or air condition.
2.Don't fix it at a place where there are obstructing material (e.g. Glass, dense clothes) which IR cannot get though.
3.Don't fix it in strong shock or vibration environment.
4.The PIR Sensor requires a 'warm-up' time in order to function properly, about 10s to1min,depend on the delay time; during this time, the signal triggered by the module is not stable, after one minute, it will be ready.

Detecting Distance: 1-10mm (Read description befor purchase); Detecting Object: Metal, Water, Glass,etc (See conditions in the description!!!); Supply Voltage: DC 6-36V
Current Output: 300mA(resistive load); Operating Temperature: -25C to +65C (Non-freezing Condition); Cable Length: 2m/6.56ft
Wire Type: DC 3 Wire Type; Switch Appearance Type: Cylinder Type; Theory: Capacitance Sensor
Description
Description:NOT ALL MATERIAL ARE SUBJECT TO THE 10MM DETECTING RANGE.
3 factors that affect the function of the sensor:
1. Material density.Most of plastic material is not detectable by a capacitive proximity sensor at a proper distance, sometimes becasue the density is low , sometimes because the plastic is too thin, for example, if you detect an empty 1mm thick plastic bottle, the detecting distance may be less than 2mm , if you fill the bottle with water ,then the detection distance could be longer than 5mm.
2. The Sensitivity, when the sensor cannot work,there is a sensitivity-adjustment screw on the back of the sensor, you can turn it clockwise with a flat head screwdriver to increase the sensitivity of the sensor
3. Load Current . High output current can result in prodct failue, Inductive load (for instance, motors which draw high current when started) is not allowed to be directly connected with this sensor, because this sensor can only provide 300mA current for the load , you can use this sensor to provide a low level signal for a PLC which requires very little current ,or you can control a small relay that requires a coil current less than 100mA.
