MICROCONTROLLER CONTROL SYSTEM FOR A CONVECTIVE DEHYDRATOR

Abstract

A microcontroller control system for a convective dehydrator has been developed. The IoT-class microcontroller provides control of the dehydrator, monitoring of the dehydration process, and transmission of telemetry data to the cloud service. Telegram bot is used as a cloud service. High-precision MEMS sensors BME-280 are used. To improve the accuracy, a mutual calibration procedure was implemented. Monitoring the air absolute moisture at the outlet of the dehydrator allows you to control the drying process in real-time. Telemetric information collected in the cloud service for the entire dehydration procedure is suitable for research and modeling of convective dehydration processes.
