01 Introduction The linear Hall sensor is a type of sensor that utilizes the principle of the Hall effect, which generates a potential difference as the magnetic induction intensity increases through its linear region. It is commonly used for measuring physical quantities, such as fuel gauges and liquid level meters. The joystick used in game … Read more
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
