“…Additionally, it supports P2P group operations that adhere to the most recent Wi-Fi P2P protocol. ESP32 was utilized to lessen network activity and the processing burden on the server [14]. One of the most often checked parameters in many industrial and commercial applications is temperature.…”

Strawberry is a horticultural commodity that produces a high economy, but in 2014 strawberry production decreased by 34.83%. The reason for the decrease in production is the unstable temperature and humidity conditions due to global warming. Another factor that causes strawberries to fail is due to the slowness of farmers in knowing changes in temperature and humidity in strawberry. The method used in this study was to compare the results of special treatment on microgreen strawberry nurseries indoor using natural vegetative methods and outdoor. System telecontrolling strawberry nursery real time with temperature and humidity parameters using a DHT22 sensor, soil moisture using a soil moisture sensor, soil pH using a soil pH sensor, time using RTC and light intensity using a light intensity sensor BH1750. The results of strawberry nurseries with telecontrolling an indoor plant height of 9 cm and a plant width of 12 cm, results of strawberry nurseries without telecontrolling treatment outdoor with a plant height of 7.5 cm and a plant width of 7 cm.

“…E SPRESSIF's ESP32 microcontroller is becoming popular in the embedded and IoT industry due to its many pros [1]. Its dual-core speeds up and FreeRTOS support attracts more and more developers [2]. Also, Espressif provides the ESP32 module, and AWS 1 certified development board ESP32-DevKitC V4 at an affordable price for makers or developers to quickly start even on a breadboard.…”

<div><p>ESP32 is becoming a popular and potential game-changer in the IoT industry.

The investigation, calculation, experiments, and LTspice simulation disclosed the result. Starting from getting relevance facts from datasheets of essential components on the board, calculated thermal conditions of the heated element, experimented to confirm the deliberate and get empirical data while code running including GPIO and WiFi, and ended with simulation ensure the data.</p><p><br></p><p>This paper concludes the following result points. The minimum supply voltage is 3.6 V to run an ESP32 module. The supply voltage should be under 10 V for both input capacitor rated voltage and LDO junction temperature rating. The thermal restriction was calculated at an ambient temperature of 25 °C and tried and tested. For a more harsh environment, this way could derate the upper limit voltage. An external power should supply current well over average 100 mA, a good 1 A. In terms of battery, this range reassures that an ESP32 can run with a single cell LiPo. Regarding the USB, both the high power and low power port can supply sufficiently. While an external supply being no less than 5.2 V, both the USB and external sources could work simultaneously.</p></div><div><br></div>
