Description:

The product’s VCC is to connect power anode (3.3-5V), the GND is to connect power negative. The DO is the TTL switch signal output.
Fixed bolt holes for easy installation
Using a wide voltage LM393 comparator
With a precision potentiometer adjustable sensitivity adjustment
Sensitivity adjustable (shown in blue digital potentiometer adjustment)
The detection angle of 60 degrees, the flame spectrum particularly sensitive
The comparator output signal clean waveform is good, driving capability, than 15mA
It can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test
Material: Plastic, metal
Operating Voltage: 3.3V-5V
Output form: DO digital switching outputs (0 and 1)
PCB size(L*W): Approx 1.26 x 0.55 inch/ 3.2cmx1.4cm

Specification:

Usage:
The flame sensor most sensitive to ordinary light is also a reaction, generally used as fire alarm and other purposes
A small panel output interface can be directly connected with the microcontroller IO port
The sensor and the flame to maintain a certain distance, so as not to damage the sensor temperature of the test flame lighters distance 80cm, the larger the flame, the greater the distance test

Package Includes:

1 x Flame Sensor Module
