The Pyroelectric InfraRed(pir) motion detection sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature.
Feature for pir sensor:
Dual compensated sensing elements in the PIR sensor are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved.
Typical Applications for motion sensor
1. Security systems
2. Burglar alarms
3. Visitor acknowledgement
4. Lighting switch control
5. Intellectualized toy, etc.
Photoresistor is a resistor which made of semi-conductor material, and the conductance changes with luminance variation. The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Photoresistor is widely used in many industries, such as toys, lamps, camera, etc.
Tipycal Applications for cds photoresistor

Light sensitive switch is a device that is used for automatically switching on and off the street lights garden lighting, passage lighting and doorway lighting etc in accordance with the natural lighting level.
The lights connected to the light sensitive switch are turned on automatically in evening when the natural light falls below 15 lux. And lights are switched off in the morning automatically when the light level reaches above 20 lux.
Eliminates the need of human operation for switching on and off any external light connected with this system.
Saves energy saves electricity , no need to manually switching on and off the light, easy to install and durable.
Applications: roadway lighting , building perimeter lighting , outdoor advertising signs , parking lot lighting, garden lighting passage lighting and doorway lighting etc.
