Interfacing Hall Effect Sensor Module with Arduino A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in industrial applications like current-sensing, position detection, and contactless switching. They are basically like a small reed switch, and when a magnetic field is around, the… |

Magnetic Polarity Detector Circuit using Hall Effect Sensor We all know that every magnet has two polarities, i.e. North Pole and South Pole, whether it is neodymium magnet, ring magnet or disc magnet. We also know that opposite poles of a magnet attract and same poles repel. But it is hard to say that which one is south pole and which one is a north pole, so to detect the poles of the magnet, here we will build a simple circuit.… |

Galvanic Isolation – Signal Isolation and Power Isolation An average household microwave oven operating at 110/220V AC can produce upto 2800V inside it, which is dangerously lethal. Besides that it also has a lower level AC voltage around 3.5V to light up the filament and a regulated DC voltage like 5V/3.3V for the digital electronics part like the display or timers to operate. Have you ever wondered… |

How to Use Hall Sensor with AVR Microcontroller ATmega16 Hall sensors works on the principle of Hall Effect proposed by Edwin Hall in 1869. The statement proposed says, “The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.” So, what could… |

Ultra-Low Power Omnipolar Hall Effect Sensors Diodes Incorporated introduced the AH1911/AH1921 digital Hall effect sensors, which combine market-leading stable operating and release points (BOP and BRP) with ultra-low power operation. The 3rd generation devices will respond to either polarity of magnetic field and use a ‘hibernating clock’ system to reduce average current consumption to 1.6µA at 3V supply.… |
