Design and construction of a low-cost energy consumption measurement device for industrial facilities: evaluation and case study for a food products conveyor company in Bogota.

Abstract

The following article describes the design and construction of a low-cost electronic device that allows real-time data monitoring of energy consumption for industrial facilities, taking the company Transportes P & M S.A.S located in Bogotá, Colombia as a case study . The development of the energy measurement device resulted from the project: “Energy efficiency project in refrigeration facilities” proposed by Sena Innova (SENNOVA), in conjunction with BIOTEC - Research Group of the Caribbean Biotechnology Center. The developed device consists of a series of sensors arranged within the refrigeration rooms and also within the electrical panels that control the refrigeration rooms. Through a series of microcontrollers (ESP32) connected to the sensors, the data is centralized to a single board computer (Raspberry pi) to then be processed and sent to a web server. All development at the hardware level was programmed using the Python language, along with the necessary libraries for reading the sensors used.
