An Hall sensor is a device that, when under the effect of a magnetic field, outputs a proportional voltage [1]. You can have a dab of paint, a hole, or a magnet for a hall-effect sensor. Its split into 2 sections because if you use only millis(), resolution at high speeds is terrible. Ifm electronic MX5 series hall effect speed sensors for non-contact detection of speed and direction of rotation. It had three wires coming out and that ticked me that may be it has some way to control its speed. When using period measurement to monitor RPM, the RPM can be calculated by using the equation: RPM = 60/Pulse period x PPR. The picture below (taken from Pololu's website) shows the typical output of an encoder. Fan RPM With Internal Hall Effect Sensor and Arduino (Intro to Hardware Interrupt and LCD Display): For my other project for work, i had to measure the rotational speed of rotor in Revolutions Per Minute (RPM) of one modified computer fan. YF-S201 Hall Effect Water Flow Meter / Sensor. The sensor simply uses at least one magnet (I use 4 to get higher update rate) and a hall switch (about $. A Hall-effect sensor is a long-lasting solution because there are no mechanical parts to wear down over time. IR reflection or hall effect magnet sensing). Call this V0. The simplest way to do so is to modify a computer fan. I have gone through various blogs on internet about interfacing acs712 current sensor with arduino and other microcontrollers. After 5 seconds Arduino calculates RPM for a minute using the given formula. In principle, any rpm sensor that outputs a PWM signal can be used by ArduPilot. So now sensor is connected to A0.
