Analysis of Power Consumption Efficiency of ESP Microcontroller Operation in the Implementation of IoT-Based Agricultural Monitoring Systems

ESP is an IoT based microcontroller. One of its uses for monitoring farming system. To produce good agricultural products, but agricultural land is far from a power source, the microcontroller's energy is limited. This difficulty is overcome by deep sleep mode to save energy. Tests were carried out on three types of ESP to determine the power efficiency level of the system's deep sleep mode. Testing is carried out by taking current and voltage data on the three ESPs during deep sleep and normal mode. The power efficiency results obtained were ESP 32 DEVKIT V1 WROOM 87.10883974%, ESP 32 DF Robot FireBeetle 99.87277596%, and ESP 8266 NODEMCU 80.2693633%. The time used for monitoring of the agricultural system produces, ESP 32 DEVKIT V1 WROOM 20 days 5 hours 38 minutes, ESP 32 DF Robot FireBeetle 186 days 15 hours 40 minutes, and ESP 8266 NODEMCU 24 days 1 hour 53 minutes.
