Abstract
This paper presents an innovative design and development of a smart device with IoT capabilities based on the ESP32 microcontroller. This is a compact embedded kit that measures atmospheric pressure, temperature, and humidity, and transmits the data to the IoT website. It features a heart rate sensor that sends data to a custom-designed Android app via Bluetooth and a compass that can sense the direction, displaying the current date and time. The compact embedded kit smart device has several potential applications, such as checking share market graphs and live sports scores through the internet. It can also be reprogrammed as a health monitoring system, drone controller, car controller, or different system controller like home automation, depending on the user's needs. Furthermore, students can connect various sensors to the device to learn embedded systems, as several embedded programs are available.
