Service business frozen processed food delivery using Reefer Container in ground shipping the more growing fast. Reefer container working maintain the temperature and humidity of the cargo being shipped in ocean and land. The failure of ground shipping using reefer containers makes the waste increase every year. Designed a prototype monitoring system for temperature, humidity and reefer container location aims to monitor each reefer container in maintaining the temperature and humidity of the cargo in land shipping. Utilization internet of things (IoT) using ESP32 board with the Blynk application, aims to allow users to directly monitor temperature, humidity and location values remotely. Test result The prototype system is able to monitor temperature with an accuracy of 98.96%, humidity with an accuracy of 99%, and location with an accuracy of 0.2 meters distance.
