Linear Light Sensor, we also call it photoresistor light sensor or phototransistor. The chip integrated inside the ldr light sensor is very sensitive to light changes. So normally it is used to detect the current ambient light level and converts the light energy into an electrical signal output.

Compared with traditional photoresistors, this kind of photosensitive resistance sensor is more environment friendly and complied with ROHS requirements. We can also make it to be SMD type with mini size. It is more and more popular now.

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.

Among those pir sensor manufacturers, Senba Sensor has become the first owner of this special technology enterprise in China.
