LM393 4 Pin IR Flame Detection Sensor Module Fire Detector Infrared Receiver Module For Arduino Diy Kit
Feature:
1. Versatile Detection: The detector is capable of detecting flames or light sources with wavelengths between 760nm to 1100nm. It can even detect flames up to 80cm away from the testing point. The larger the flame, the farther away the detector can detect it.
2. Wide Detection Angle: The detector has a detection angle of around 60 degrees and is especially sensitive to flame spectra.
3. Adjustable Sensitivity: The sensitivity of the detector can be easily adjusted using the blue digital potentiometer shown in the picture.
4. Clean Signal Output: The comparator output is clean and has excellent waveform quality, with a driving capability of over 15mA.
5. Multiple Output Options: The detector offers DO digital switch output (0 and 1) and AO analog voltage output. It also includes fixed bolt holes for easy installation and uses the LM393 comparator for wide voltage use.
Specification:
Working voltage: 3.3V-5V
Small PCB size: 3.2x1.4cm
Product weight: 2g
Module usage instructions:
1. Flame sensors are the most sensitive to flames and also respond to ordinary light, and are generally used for flame alarm and other purposes.
2. The output interface of the small board can be directly connected to the IO port of the microcontroller
3. The sensor should be kept at a certain distance from the flame to avoid high temperature damage to the sensor. The flame distance for testing lighters is 80cm, and the larger the flame, the farther the testing distance is
4. The small board analog output method and AD conversion processing can achieve higher accuracy
