ITEM NAME:1 pcs blue metal 4-pin flame sensor module / fire detection module Infrared Y1A1 1 pcs blue metal 4-pin flame sensor module / fire detection module Infrared Y1A1 Color: blue Material: metal Size: 4.6*1.4*1cm Uses: all kinds of flames, fire detection 1, the flame sensor is the most sensitive to the flame, is also a response to ordinary light, generally used for flame alarm and other purposes. 2, a small board output interface can be connected directly with the microcontroller IO port 3, the sensor and the flame to maintain a certain distance, so as to avoid damage to the sensor temperature, the flame test on the lighter distance of 80cm, the greater the flame, the longer the test distance 4, small board analog output and AD conversion process, you can get higher accuracy Module Features: 1, can detect the flame or the light source in the range of 760 nm to 1100 nm, the flame test flame distance is 80 cm, the greater the flame, the farther the test distance; 2, detection angle of about 60 degrees, the flame spectrum is particularly sensitive; 3, adjustable sensitivity (figure blue digital potentiometer adjustment); 4, the comparator output, the signal clean, good waveform, strong driving ability, more than 15mA; 5, with adjustable precision potentiometer to adjust the sensitivity; 6, working voltage 3.3V-5V; 7, the output form: DO digital switch output (0 and 1) and AO analog voltage output; 8, with fixed bolt hole, easy to install 9, small board PCB size: 3.2cm x 1.4cm; Package Contents: 1 X 4-pin flame sensor module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..Module Features Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
