Agriculture sensors are crucial in contemporary agriculture. The use of sensors in many agricultural processes reduces crop pollution, increases productivity, and lowers operational costs. Among other agricultural sectors, the mushroom industry is relatively new and modest. Because the majority of mushroom plantations are small-scale, their production capacity is limited by insufficient integrated environmental systems and a lack of funds to improve facilities. This project offers an environmental monitoring and control system based on an ARM Processor that uses the Internet of Things to monitor and regulate environmental parameters such as temperature, humidity, and light intensity in a mushroom farm. It allows users to use an Android device to monitor temperatures and humidity in a mushroom farm using the web portal UBIDOTS. The control algorithm can autonomously operate equipment in a mushroom farm, utilizing sensor data to maintain the environment in ideal conditions for mushroom cultivation. The settings are presented on an OLED screen in the farming room. As a result, the collected information is on the cloud. The Arduino comprehensive development environment uses to write the controller's code in the Arduino programming language, then debug and compile the code before burning it into the microcontroller. The outcome demonstrates the viability of remote environmental monitoring over the Internet. Perhaps helpful to Indian farmers, it reduces the need for human labour and automates manufacturing.
