SMD Type Light Sensor 3528 to Replace Photoresistor

Overview

A Light Sensor is also what we call phototransistor. It is widely used to detect the current ambient light level and converts the light energy into an electrical signal output. Normally it will appear in light control switches and various infrared detection equipments.

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.
