Measurement Data Collection Device Based on ESP32 for Digital Laboratory

Abstract

The potential use of digital laboratories is constantly growing every year, as such a device allows you to conduct research in such fields as biology, physics, chemistry and other natural sciences. It is proved that the use of modern equipment increases the efficiency of laboratory classes in schools. Today, there are a large number of educational digital laboratories, which find many areas of use, from laboratory work at school to laboratories at universities. However, if you analyze these digital labs, you can see that they do not have a user-friendly interface and settings. The purpose of this work is to review existing solutions, as well as find solutions to create an improved version of digital training laboratories. The main disadvantage of existing solutions is the lack of data transfer via Wi-Fi or Bluetooth, as well as connection to a computer or smartphone, which could significantly improve the process of working with such a device. One of the solutions to this problem is the creation of digital training laboratories based on the ESP-32 microcontroller. After analyzing the existing digital laboratories, we can conclude that this area needs improvement, as existing technologies allow to create much better devices in terms of ease of use and opportunities for educational purposes. Bluetooth and Wi-Fi are the main elements, the addition of which will significantly improve digital laboratories. One such solution is the ESP-32 microcontroller, as it includes these modules, and its technical characteristics allow you to create a device that will collect data simultaneously from many connected sensors. The creation of a digital laboratory with such characteristics will significantly improve the process of laboratory work in schools and universities, as well as allow more organized distance learning online, which will have a positive impact on the educational process in schools and universities.
