Infrared pir motion sensor
3*4mm window, wide angle
Long distance
High sensitivity to human motion
Direct supply, good price
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.
100pcs/box, 18000pcs/CTN.
5mm Photoresistor/LDR sensor
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.
