Implementation of an Automated Climate Chamber for Calibrating Measuring Equipment using Arduino MEGA and an LCD Module

Abstract

This article describes the implementation of an automated climate chamber designed for the accurate calibration of thermohygrometers and other temperature and humidity measurement equipment. Addressing current calibration limitations, which cause production delays, customer dissatisfaction, and increased operating costs for the company EQUINLAB SAC, this project proposes a low-cost solution based on Arduino MEGA. The automated chamber integrates heating, cooling, humidification, and dehumidification systems controlled by an Arduino MEGA, with real-time data visualization via an LCD module. The design includes a custom electronic board, detailed electronic and electrical schematics, and 3D drawings of the chamber. This innovation seeks to improve calibration capacity and efficiency, offering a robust and economical alternative to commercial solutions, which ultimately improves service quality and reduces operating costs.
