Selection of ESP32 operating parameters in order to reach optimal energy efficiency during calculations

In the era of technological processes automation development, the popularization of house automation, constant limitation of human participation in these processes, as well as the intensification in the field of broadly understood IoT, such devices are increasingly used for remote monitoring and control of various processes. In recent years, the ESP32 platform has gained a significant increase in the popularity of the IoT market. It is often used for logging and remote controlled devices, mostly in smart home solutions. Such devices often have to be small and have long battery work-time. The test results presented in the article will allow for a proper selection of working parameters in order to achieve the most optimal energy efficiency (smallest losses) while performing the assumed task.
