IOT Based Biogas Monitoring System using Node MCU ESP32S

Abstract

The production of biogas (CH4) happens when all the necessary conditions like temperature, pressure, humidity and the moisture content are maintained. If required conditions are correctly maintained, then there will be maximum anaerobic digestion which will add up to maximizing the output. The monitoring of the biogas using IOT will help in monitoring and maintaining right condition for the gas production. In this paper, it is discussed about “monitoring biogas reactor using Node MCU ESP32S”. The different hardware components and software framework are used to develop the system. The hardware components used are temperature sensor (DS18b20), soil moisture sensor (Yl-69), temperature, pressure and humidity sensor (BME280), methane sensor (MQ4), piezo buzzer (PBUZZ5), and Node MCU ESP32s. And the software platform used are Android studio, proteus, ruby language, and PostgreSQL. The sensor data will be displayed in the mobile application where if a certain value for the sensor is not in optimum range then the user will be notified through app notification and even with the piezo buzzer. The user can intervene at the right time to maintain the right condition for biogas production. Through such a system it will drastically reduce the hectic manual work and helps users to know when to intervene as users will be notified through app notification if parameters like temperature, moisture, and methane content are not in optimal range. Whereby such a system will help in optimum production of biogas.
