In this tutorial, we will build a data logger using Raspberry Pi Pico and MicroPython. We will log temperature and humidity readings acquired from a DHT22 sensor to a microSD card. The program creates a .txt file on the microSD card and appends fresh temperature and humidity readings every 30 seconds. This project demonstrates a … Read more
In this tutorial, we will learn to create STM32 Blue Pill BME280 data logger to log sensor readings to a microSD card with STM32CubeIDE. We will create a .txt file in our microSD card through programming our Blue Pill board and consequently log current temperature(°C), pressure(hPa), and humidity(%) readings to that file after every second. … Read more
In this guide, we will show you how to log sensor readings to Firebase Realtime database along with current timestamps. We will use ESP8266 NodeMCU along with BME280 sensor for this project. Firstly, we will create a Firebase project to log temperature, pressure, and humidity readings along with timestamps. The Firebase project data will be … Read more

In this user guide, we will learn how to log GPS data acquired from NEO-6M GPS module to a microSD card using Arduino and Arduino IDE. The GPS data will consist of a latitude, longitude, and altitude values as well as the current date and time. We will create a .txt file in our microSD … Read more
In this user guide, we will learn how to log DS18B20 temperature sensor readings along with timestamps to a microSD card using ESP32 and Arduino IDE. Furthermore, the current date and time will also be logged with each temperature sensor reading. We will use the ESP32 NTP server to request updated time stamps. In order … Read more
In this user guide, we will learn how to interface a microSD card with ESP32 using the microSD card module or connector and Arduino IDE. This module provides an SPI interface to connect an SD card module with any microcontroller which supports the SPI communication interface. Using a microSD card becomes very handy for applications … Read more
