Feature: 1. [IP Flame Sensor Module] Can detect flames or light sources with wavelengths ranging from 760 to 1100nm. The flame test distance for lighter is 80cm, the larger the flame, the farther the test distance should be. 2. [Highly Sensitive] The detection angle of this flame sensor module is about 60 degree, which is particularly sensitive to the flame spectrum, provides accurate fire source detection for various types of fires. 3. [Adjustable Sensitivity] The sensitivity can be adjusted through the digital potentiometer to meet different fire detection needs. 4. [Easy to Install] With a size of 50x26mm and a thickness of 19mm, designed with fixed bolt hole, this fire detection module is very convenient to install. 5. [Wide Application] This fire alarm sensor module is very suitable for fire detection in homes, offices, industrial settings, and other environments. Specification: Item Type: IR Flame Sensor Module Material: PVC Power Supply Voltage: 12VDC Current: >150mA Load: 250V 10A AC or 30V 10A DC Application: Fire source detection of various fires Size: Approx. 50x26mm/1.97x1.02in Thickness: Approx. 19mm/0.75in. Package List: 1 x IR Flame Sensor Module Note: 1. The flame sensor is highly sensitive to flames and also responds to sunlight. It is often used for flame alarms and other purposes. 2. By adjusting the potentiometer, you can set the strength at which the sensor detects flames. When the flame exceeds the set threshold, the relay is connected, and the common end is connected to the normally open end. When the flame is below the set threshold, the relay is disconnected, and the common end is connected to the normally closed end. 3. The common end, normally open, and normally closed ends function as a double control switch. When the relay coil is powered, the common end is connected to the normally open end. When there is no power, the common end is connected to the normally closed end. 4. The sensor should be kept at a certain distance from the flame to prevent damage due to high temperature. The distance for testing flame with a lighter is 80cm, and the larger the flame, the farther the testing distance.
