Battery powered e-ink wireless sensor with display

This project use Magnetometer sensor for detecting magnetic field near device if magnetic field detected and cross the threshold value then its show the current availbilty. you can see X, Y,X value on reltime and on graph data.

“I am involved in EDGE IoT and Robotics at Jahangirnagar University (JU), gaining hands-on experience in designing IoT solutions and robotic systems, integrating sensors, data processing, and automation. This project is enhancing my technical skills and providing valuable insights into real-world applications of IoT and robotics.”

This project implements a digital RPM (Revolutions Per Minute) meter using an Arduino-compatible microcontroller, a Hall effect sensor, and an I2C LCD display. The system measures the rotational speed of a shaft or wheel and displays the RPM in real-time on the LCD screen.
