SISTEM MONITORING SUHU NIRKABEL PADA COLD ROOM BERBASIS DATA LOGGER DENGAN INTEGRASI PLATFORM TELEGRAM
Abstract
Abstract. Temperature stability in the cold room is an important factor in maintaining product quality, so an IoT-based monitoring system is needed that is able to record temperature data periodically and provide online notifications through integration with the Telegram platform. This study aims to determine the technical obstacles that could potentially occur in implementing a wireless temperature monitoring system and whether the wireless temperature monitoring system simplifies the routine temperature monitoring process by the maintenance team. The system was built using an ESP8266 microcontroller (NodeMCU) integrated with a DS18B20 sensor, a microSD module as a data logger, and online notifications via the Telegram application. Based on the research results, the system was designed using an ESP8266 microcontroller (NodeMCU) integrated with a DS18B20 temperature sensor, a microSD module for data storage, and the Telegram application for real- time notification. Test results indicate that the system is capable of continuously and stably monitoring temperature, with average temperature values ranging from 3.90 °C to 4.20 °C and temperature fluctuations still within acceptable limits for a cold room. The system is also capable of detecting temperature anomalies above the 10 °C threshold and sending online warning notifications via Telegram with a response time of less than or equal to 5 seconds.
