Flame - Fire Sensor Module

A flame detector is a sensor designed to detect and respond to the presence of a flame or fire.

Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system. When used in applications such as industrial furnaces, their role is to provide confirmation that the furnace is properly lit; in these cases they take no direct action beyond notifying the operator or control system. A flame detector can often respond faster and more accurately than a smoke or heat detector due to the mechanisms it uses to detect the flame.

Features of Flame Sensor

• Can detect a flame or in a 760 nanometer wavelength of ~ 1100 nm range of the light, lighter flame test distance of 80cm, for the greater flame, the farther the distance test

• The detection angle of 60 degrees or so, particularly sensitive to the flame spectrum

• Sensitivity adjustable (shown in blue digital potentiometer adjustment)

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

• With adjustable precision potentiometer sensitivity adjustment

• The working voltage of 3.3V-5V

• The output format : DO digital switching outputs (0 and 1) and AO analog voltage output

• A fixed bolt holes for easy installation

• Using a wide voltage LM393 comparator

Instructions for use

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

• The output interface can be directly connected to the microcontroller IO port.

• With the flame sensor to maintain a certain distance, so as not to damage the sensor temperature, the flame of a lighter test distance 80 cm, for the greater flame, the farther the distance test.

• Analog output and the AD conversion process, can achieve higher accuracy.
