Analog Output 3- 15V Passive Infrared Sensor D204B

Overview

D204B come standard with enhanced immunity to EMI (Electro-Magnetic Interference). It widely used in security system.

Senba PIR sensor can detect the wavelengths humans emit which is 8-10um, but Senba PIR can detect 7- 14um. It can be used in security and automation applications. For security applicance, PIR sensor are integrated into the alarm system. There are ceiling type and wall hanging type. For automation applications, PIR sensor d204b can be integrated into the light control system, automatically turn on the light when somebody enter the detect rang, automatically turn off the light when sombody exit the detect range.

Sensor Switch

The PIR motion sensor adopts high-performance infrared detector. As long as human cross through its detection range, the infrared switch generates an electrical signals.

FAQ
1. Why is PIR sensor called passive?

The sensor is called passive because it doesn't emit light to get measurements. The sensor in PIR is actually split into two parts. The reason for that is to measure motion. ... The sensor is also sensitive enough to even detect IR radiation source movement while the object is already in it's field of view.

2. How far can a motion sensor detect?

D204B can detect up to distances of 8- 10M.

As one of the most professional pir sensor manufacturers in China, Senba Sensing Technology Co.,Ltd., was founded in 2005, with the focus on producing the top quality photoelectric components. If you want to know more details, just feel free to contact us!

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...

How to Use Ldr Sensors to Realize the Circuit Control of Photoswitch?

图片
  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...

Some Knowledge of LDR Sensor

图片
  LDR sensor (photoresistor light-dependent resistor, and the latter is abbreviated as ldr) or photoconductor, is commonly made of cadmium sulfide, as well as selenium, aluminium sulfide, lead sulfide and bismuth sulfide. These fabricated materials have the characteristics of rapid reduction of resistance under the irradiation of specific wavelength light. This is because the carriers generated by light are all involved in conduction, and it will cause drift under the action of an applied electric field, and electrons run to the positive pole of the power supply, and holes run to the negative pole of the power supply, so that the resistance value of the photoresistor sensor decreases rapidly.   Usually, many types of LDR  sensor   are  made into thin sheet structures to absorb more light energy. When it is irradiated by light, the electron-hole pairs are stimulated in the semiconductor sheet (photosensitive layer) to participate in conduction, which enhances the...
