IoT solution for controlling and monitoring temperature in bioreactor

This paper presents the development and implementation of an IoT-based system for monitoring and controlling temperature in a bioreactor. The system comprises an ESP8266 microcontroller, an OLED display, a solid-state relay (SSR), a temperature sensor, and a peltier module. The entire system operates an air or water pump which delivers warm or cool into the bioreactor by using a bypass. This work emphasizes the electronic design aspects and the implementation of IoT capabilities. By utilizing the microcontroller's PWM signal to modulate the SSR output, the system achieves precise temperature regulation. The IoT functionality enables real-time data acquisition and transmission to a cloud-based platform, facilitating remote monitoring and control of the bioreactor operation.
