Microbit | Sensor Series 11 – Analog Hall Sensor

Microbit | Sensor Series 11 - Analog Hall Sensor

01 Introduction The analog sensor utilizes the Hall effect to provide an analog output of magnetic field strength. It can not only detect the presence of a magnetic field but also measure its intensity. Compared to digital output Hall effect sensors, it offers higher positional detection accuracy. 02 Principle This analog Hall sensor uses the … Read more

Microbit Sensor Series 10 – Hall Effect Sensor

Microbit Sensor Series 10 - Hall Effect Sensor

01 Introduction The Hall effect sensor is a type of sensor that detects the presence of a magnetic field. Similar to the linear Hall sensor introduced earlier, it does not provide a linear output of magnetic field strength but can only indicate whether a magnetic field is present. 02 Principle This Hall effect sensor uses … Read more

Micro:bit Sensor Series 09 – Flame Sensor

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
