Micro:bit Sensor Series 09 - Flame Sensor

01 Introduction The flame sensor is commonly used to detect flames or infrared light of specific wavelengths (760nm-1100nm). It has a detection angle of approximately 60° and is particularly sensitive to the flame spectrum. The sensitivity is adjustable (as shown by the blue potentiometer in the image). The detection distance for flames is related to … Read more
