NHR0057 4 pin Flame Sensor Module

Availability: In Stock



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

The detection angle of 60 degrees, the flame spectrum particularly sensitive

Sensitivity adjustable (shown in blue digital potentiometer adjustment)

The comparator output signal clean waveform is good, driving ability, than 15mA

With a precision potentiometer adjustable sensitivity adjustment

Operating Voltage 3.3V-5V

The output in the form: DO digital switching outputs (0 and 1) and AO analog voltage output

A fixed bolt holes for easy installation

Small plates PCB size: 3.2cmx1.4cm

Using a wide voltage LM393 comparator

Suits for Various flame, fire detection


Module for use:


The flame sensor most sensitive to ordinary light is also a reaction, generally used as fire alarm and other purposes.

Asmall 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

Small plates analog output mode and the AD conversion process, you can get higher accuracy
