Hall Effect digital speed sensors powered by 5-24 VDC, provide NPN open collector output, compatible with a PLC digital I/O. Its pin out and pins definition/working. Installing the ESP32 Board in Arduino IDE (Windows, Mac OS X, and Linux) ESP32 Hall Effect Sensor: Unit 6: ESP32 with PIR Motion Sensor - Interrupts and Timers:. Variable Reluctance Sensors Engine control computers (ECU) require an input to determine angular position of the crank and/or camshaft.
