FAQ
1.Can PIR sensor detect cars?
PIR-based Motion Detection: In this case motion is detected by means of a PIR sensor, a passive infrared sensor. This sensor detects emitted infrared energy from objects (humans and animals, but also cars) in the form of heat.
2.Do PIR sensors work in the dark?
Yes, motion sensors work in the dark. The way that a motion sensor detects movement has nothing to do with how light or dark it is in the immediate area. ... Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.

The Application of the Idr Sensor

1. Electronic photometry The photometer can be used to measure the brightness of people and objects, so as to help the photographer choose the appropriate exposure speed. The following is the schematic diagram of the electronic photometer. The ldr sensor  changes the intensity of light into the difference of resistance value, so that the brightness can be displayed directly by different currents flowing through the meter. Among them, R1 and R2 are used to adjust the surface calibration and W is used to control the sensitivity of the meter head. 2. Infrared thermometry The infrared light radiated by the measured object is modulated into 800Hz optical signal by a modulation disc with a filter, which is approximately sinusoidal wave. The modulated light entering into the idr sensor is converted into electrical signals and then sent to the FET amplifier for amplification. The output U0 can reflect the temperature. In order to reduce the influence of noise and temperature c...

       The company head quarter and the manufacturer facility are located in a beautifully landscaped industrial park, named after Senba, in Nanyang, Henan. In order to provide better customer services, we also have set up branches in Shenzhen, Ningbo, Wenzhou. Until now, Senba   has become the most advanced manufacturer specialized in PIR sensor technology   in China.   How to Use Ldr  Sensors to Realize the Circuit Control of Photoswitch? Ldr sensors are sensitive to light sticking. The stronger the light, the smaller the resistance value; the darker the light, the greater the resistance value. So we can use this characteristic to construct the ldr sensor circuit , and cooperate with relay/triode/MOS transistor to realize the photoswitch. Next, the ldr switch circuit   of realizing photoelectric switch by using ldr sensor, ldr transistor  and relay is introduced.   1. What is Ldr Sensor The working principle of ldr sensor is based...

  Ldr sensors are sensitive to light sticking. The stronger the light, the smaller the resistance value; the darker the light, the greater the resistance value. So we can use this characteristic to construct the photosensitive circuit, and cooperate with relay/triode/MOS transistor to realize the photoswitch. Next, the circuit of realizing photoelectric switch by using ldr sensor, transistor and relay is introduced.       1. What is Ldr Sensor The working principle of ldr sensor is based on the internal photoelectric effect. The ldr photocell is very sensitive to light. Without light, ldr sensor presents a state of higher resistance value. Under strong light, its resistance value decreases rapidly, and presents a lower resistance value. The following is the physical diagram and characteristic curve of the ldr sensors.       2. Design of Optical Switch Circuit-Triode Implementation The circuit of the photoelectric switch is mainly composed of ldr sensor...
