Design of DC-DC Converter for ESP8266 Based IoT Sensor Nodes

Abstract

In this article, we present a design of an improved DC-DC converter for low power Wireless Sensor Node using IoT. New research shows that the main drawback of future wireless sensor networks is energy storage, collection, and processing. WSNs are installed in remote locations and are powered by photovoltaic panels and batteries. In both cases, the power supply is variable. A DC-DC converter is a device that adjusts the source output voltage of a load. In this research, we have designed a DC-DC converter for ESP8266 based sensor nodes powered by battery. We have simulated the DC-DC converter using MATLAB with adding several protection and controlling features. This includes a PID controller for transient stability. This model output gives high efficiency DC power supply with very low ripple rate. Practically most of the failures in electronic devices occur due to power supply failures. This is the best solution for sensor nodes with long lasting life span.
