Controlling an IoT device remotely using a website hosted on GetHup. The website controls data values in a Firebase database, and the data is read using an ESP32 module in the IoT device. This module controls everything.
The device has a gas sensor and two motors. It receives readings from the gas sensor, and if the gas level exceeds the normal range, it sends a warning and the device sounds an alarm. The speed and direction of rotation of the motors are controlled using the location.
It was one of the successful university projects; it had no specific goal other than experimentation.
