Herbs Go Digital: IoT Monitors Temperature and Humidity Automatically

This article aims to demonstrate the use of the Internet of Things (IoT) in a company by installing sensor devices to monitor environmental conditions automatically and continuously. Before IoT devices, monitoring processes relied heavily on inconsistent manual inspections. In the herbal and pharmaceutical industries, temperature and humidity monitoring are essential. The DHT11 and DHT22 sensors are used in conjunction with the ESP32 microcontroller to facilitate real-time temperature monitoring. The collected data is recorded in a MySQL database and displayed through HTML and PHP-based web dashboards. This article compares the performance of both sensors and discusses their potential mass application in enterprises. This IoT system implementation changes the monitoring process from manual to automated and continuous, enabling historical data collection for further analysis. The results show that IoT integration can improve efficiency and accuracy in monitoring enterprise environmental conditions.
