This ESP32-CAM guide shows the users an easy way to capture photos through ESP32-CAM and save it to microSD card. In order to save battery, ESP32-CAM will remain in sleep mode for most of the time and wake up from deep sleep whenever the RST button will be pressed. After wake up from deep sleep, … Read more
In this user guide, we will learn how to log sensor readings acquired from BME280 sensor to a microSD card using Arduino and Arduino IDE. We will create a .txt file in our microSD card through programming our Arduino board and consequently log current temperature(°C), pressure(hPa), altitude(m) and humidity(%) readings to that file after every … 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 host ESP32 web server files on a microSD card. In other words, we will build a web server that serves the files to a client saved on the microSD card. Storage data including text, video, audio, CSV, HTML, JavaScript, and CSS files can all be conveniently … 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
