โมดูลตรวจจับเปลวไฟและสวิตช์รีเลย์ (5V) Flame Sensor with Relay Module

• Can detect flames or light sources with a wavelength in the range of 760 nanometers to 1100 nanometers, the lighter test flame distance is 80cm The bigger, the farther the test distance
• The detection angle is about 60 degrees, which is particularly sensitive to the flame spectrum
• The sensitivity is adjustable (adjusted by the blue digital potentiometer in the figure)
• The comparator output directly triggers the relay
• The external dimensions are: 50x26mm , 19mm thick, with fixing bolt holes, easy to install
• Output with blue terminal block, convenient wiring

• power supply voltage: 5VDC
• Current: greater than 150mA
• load: 250V 10A AC or 30V 10A DC

Instructions for use of the module:
1. The flame sensor is the most sensitive to flame, and it is also responsive to sunlight. It is generally used for flame alarm and other purposes.

2. By adjusting the potentiometer, the intensity of the sensor's flame can be set. When the flame exceeds the set threshold, the relay pulls in, and the common end is connected to the normally open end. When the flame is below the set threshold, the relay is turned off The common terminal and the normally closed terminal are connected

3. The common terminal, normally open, normally closed three ports are equivalent to a dual control switch, when the relay coil is energized, the common terminal and the normally open terminal are connected, when there is no electricity, the common terminal and Normally closed end conduction

4. Keep a certain distance between the sensor and the flame to avoid high temperature damage to the sensor. The flame distance is 80cm for the lighter. The larger the flame, the farther the test distance.
