Serial Monitor is a free Chrome add-on designed for users who need to interact with serial ports directly from their browser. This tool allows for easy reading from and writing to serial ports, similar to the functionality found in Arduino's IDE. It is particularly useful for developers and hobbyists working with hardware that communicates via serial connections, enabling quick and efficient data transfer and control.

Built on the browserify/npm package browser-serialport, Serial Monitor provides a user-friendly interface that simplifies the process of managing serial communications. Users can seamlessly connect to their devices, monitor data in real-time, and send commands directly from the Chrome browser. This add-on is ideal for anyone looking to streamline their development workflow with hardware projects.
