Monitoring temperature and humidity levels in real-time is essential for various manufacturing processes, as well as for applications in home automation and weather stations. A significant portion of FMCG products requires precise temperature and humidity control to maintain their quality. To achieve accurate control, it’s necessary first to monitor these parameters, meaning they must be…

ESP32 and ESP8266 are popular Wi-Fi development boards commonly used in the Internet of Things (IoT) application development. These Arduino-compatible microcontroller boards are easy to prototype with and suitable for production versions. ESP32 is a powerful 32-bit microcontroller featuring multiple GPIOs, 12-bit ADCs, a DAC, touch pins, and serial interfaces such as I2C, SPI, UART,…

In the previous tutorials, we discussed Internet of Things (IoT) platforms, including AWS IoT Core. Any IoT solution of considerable size or complexity typically requires a platform. An IoT platform simplifies device fleet management, accelerates application development, facilitates data handling and analysis, and facilitates integration with other services. What’s more is that the selected platform…

As health and wellness become increasingly important, the ability to monitor vital signs, such as heart rate, is more valuable than ever. In this circuit design, we’ll build a heart-rate pulse sensor BPM (beats per minute) meter using an OLED display and the widely available Arduino UNO microcontroller. Understanding the project Before we begin, it’s…

In this project, we’ll create a standalone web server using an ESP8266 that serves as a weather station, displaying current temperature and humidity readings from a DHT22 sensor. The server will be programmed using Arduino IDE and can be accessed from any device with a web browser on your local network. It will use a…
