IR Infrared 3 Wire Flame Detection Sensor Module Smartsense For Arduino

Description:

1. When the module detects an obstacle in front of the signal, the green light on the board will turn on, while the output signal port will remain at a low level. The module detects a distance of 2~30 cm, with a detection angle of 35°. The distance can be adjusted clockwise using the adjustment potentiometer to detect a greater distance. turn the potentiometer counterclockwise to reduce the detection distance.

2. Active infrared sensors detect reflection, so the reflectivity of the target detection range is essential. The minimum detection distance is black, maximum is white.

3. The output port of the OUT sensor module can be directly connected to the IO port of the microcontroller, you can directly drive a 5V relay; Connection: VCC-VCC; GND GND; OUT-IO.

4. Use the LM393 comparator, stable.

5. Can be used for 3 to 5 V DC power supply modules. When the power is on, the red indicator light turns on.

6. With 3 mm screw holes, easy and secure installation. Board dimensions: 4.7 x 1.4 cm.

Dimensions de la carte : 4,7 x 1,4 cm.

7. Each output module comparing the threshold voltage has been adjusted by the potentiometer and is correct. Do not arbitrarily adjust the potentiometer unless there are exceptional circumstances.
