사람 검출 적외선 센서 -5V, Low/High
(Human Detection Infrared Sensor -5V)
개요
- 본 제품은 사람 검출 적외선 센서 -5V, Low/High 입니다.
- 약 1미터 거리 이내에 사람이 검출되면 High 출력을 내보내는 제품입니다.
- 측정 감도의 조절이 가능합니다.
- 5V-12V로 동작합니다.
특징
- 1、Operating Voltage:DC 5V~12V
2、Sensing distance:0cm~100cm, adjustable distance (sensing distance and obstacle color have a certain error, light color is far, dark color is close)
3、Sensing distance adjustment method:Automatically calibrate the sensing distance by pressing the button
4、Sensing angle:10~15°cone angle
5、Induction method:Proactive approach
6、Quiescent Current:<3.5 mA
7、No-load working current:5~50mA(The greater the sensing distance, the greater the working current)
8、High level output current:≤1.2mA sourcecurrent
9、Low-level output current:≤300mA sinkcurrent
10、NPN disconnect output current:0mA
11、NPN closed output current:≤300mA sinkcurrent
12、output method:High and low level signal output / switch value NPN output
13、Indicator light:Red light is on
14、working environment:Illumination: sunlight 10000Lx, incandescent lamp 3000Lx
(Can work normally under direct sunlight 1 meter away from 1000W energy saving lamp)
15、Load current:<100mA
16、Working temperature:Working temperature-20~85℃
17、Material:PC-V0 fireproof material
18、Waterproof performance:IP55 - Note: ①Since the output of the digital circuit has only two levels of high and low (0, 1), when the output is high, the output terminal generally provides current to the load, and the value of the current provided is called "source current"; In normal output, the output terminal is generally to absorb the current of the load, and the value of the absorbed current is called "sink (in) current".

- Sensing distance adjustment
1. Place a piece of kraft paper about 80cm * 80cm 70cm in front of the sensor (set according to user needs within the range of 10~150cm).
2. The sensor is powered on.
3. Open the back cover of the sensor and firmly press the small dot button in the upper right corner.
4. After the indicator light is on for about 1 to 2 seconds, release the button to enter the automatic sensing distance mode. Keep the sensor and the cardboard still, and there can be no obstructions between them. Waiting for about 10 seconds, the indicator will stop flashing and automatically save data; automatically return to normal working mode. The pitch adjustment is complete.Sensing range and angular displacement
Precautions for use
1. The infrared receiving device is interfered by strong light (normal indoor light will not be affected, when the light is too strong, the sensitivity will be reduced and the distance will become closer). When installing, try to avoid direct light on the probe to make the sensing distance closer and affect the function.
2. The infrared sensor is based on the principle of diffuse reflection of light, which is easily affected by the color of the reflected object (sensed object). White is the farthest, black is the closest, and the black and white color sensing difference is large; when using the sensor, try not to place white in front of the sensor. Objects to avoid misoperation.
3.When installing, avoid working in an environment with high dust concentration (because high concentration dust is equivalent to sensing objects, which will cause the sensor to malfunction) to avoid misoperation.
