Fast Response Light Dependent Resistor φ10 Series for Light Switch

Overview

A photoelectric device can be either intrinsic or extrinsic. An intrinsic semiconductor has its own charge carriers and is not an efficient semiconductor, for example, silicon. In intrinsic devices the only available electrons are in the valence band, and hence the photon must have enough energy to excite the electron across the entire bandgap.

Applications

Lead sulfide (PbS) and indium antimonide (InSb) LDRs (light-dependent resistors) are used for the mid-infrared spectral region.


FAQ

1. What is the test condition?

Light resistance Irradiate by 400-600Lux light for two hours, then test with 10Lux under standard light source A(as colour temperature 2856K)

Dark resistance Refer to the resistance value ten seconds after the 10Lux light is shut up.

2. Samples.

Free samples are available for testing.

FAQ
  • Is Wave Soldering Recommended?

    Wave soldering is likely to cause degradation of product performance. Wave soldering is not recommended. Generally we recommend to solder by hand.


  • Can PIR Sensor Detect Animals?

    PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.

  • Do PIR Sensors Work Through Glass?

    No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.


  • What Is The Package?

    1. PIR sensor: Graphic Carton-> Carton

    2. LDR: plastic bag -> Graphic Carton -> Carton

    3. Fresnel Lens: plastic bag -> Carton


  • What are the Factors that Affect the Performance of the Product?

    1. When there is dirt on the window, it will affect the detection performance.

     

    2. When the ambient temperature and the human body temperature are close, the detection and sensitivity are significantly reduced, sometimes causing short-term failure. The recommended minimum temperature difference between the ambient temperature and the human body temperature needs to reach at least 4 ° C.

     

    3. When designing the circuit, pay attention to anti-interference measures to prevent false alarms caused by radio frequency interference.
