Using Node-RED to Display Data from ESP32 and DS18B20 Sensor

Node-RED is an open-source flow-based development tool for visual programming, originally developed by IBM for wiring together hardware devices, APIs, and online services as part of the Internet of Things. In this article, we will explore how to use Node-RED to display temperature data from an ESP32 microcontroller connected to a DS18B20 temperature sensor. Prerequisites Before we start, ensure you have the following: ESP32 Development Board: A microcontroller with Wi-Fi and Bluetooth capabilities.
