In this illustration we will going to wire the 3144 Hall Effect Sensor Module. Hall Effect Sensor are designed to respond in a wide range of positive or negative magnetic field.

Linear Sensor are critical to the performance to their sensitivity and linearity over their specified operating temperature range and immune to most environmental disturbance that may affect optical or mechanical devices, such as vibration, moisture, dirt or oil films, ambient, lightning, etc.

Linear Hall Effect Sensor are commonly used in current sensing, power sensing (watt-hour-metering), current trip-point detection, strain gauge, biased (magnetically) sensing applications, Ferrous metal detection, proximity sensing, Joy-Stick with intermediate positions sensing, liquid-level sensing, temperature / pressure / vacuum sensing, throttle or air valve positions sensing, non-contact potentiometers, etc.

Required Components

  • UNO / MEGA / NANO / PRO / DUE / RPI / ESP8266 / STM
  • Hall Effect Sensor Module
