| Summary: | In Malaysia, most farmers depend on traditional agricultural practice. The adaptation of modern agricultural technology plays an important role in improving the overall efficiency and productivity. In modern agriculture, the internet of things (IoT) connects farmers to their farms through sensors to facilitate monitor of real-time conditions of their farms from anywhere. Oyster mushroom is widely cultivated among farmers in Malaysian. Although this crop is widely consumed and cultivated, it remains overshadowed by traditional cultivation approaches which result in low productivity, high labor efficiency, high cost and effort. Thus, this study aimed to develop a monitoring system based on IoT on environmental conditions of a mushroom farm, namely temperature, humidity, moisture and light intensity. Oyster mushroom requires an optimum temperature between 26 and 29 °C, humidity from 85 to 95% and carbon dioxide not exceeding 600 ppm. Sensors were placed at fixed locations in the farm to measure the parameter status transmitted to a remote monitoring station via low-power NodeMCU. The data obtained were stored on the cloud platform. The codes for the controller were written in the Arduino programming language, debugged, compiled and burned into the microcontroller using the Arduino integrated development environment. The results showed the success of monitoring environmental conditions through internet access from anywhere. This approach will reduce human efforts and also help to automate production, which benefits farmers in Malaysia. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
