Many HVAC systems in North America operate off 24V systems, which can be readily upgraded with off-the-shelf  smart ...

Cheap and cheerful.

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

Each platform keeps the RM3100 sensor logic in a separate reusable driver/library file, while the runnable demo entrypoint only performs platform setup, calls the driver, and prints results.

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...
