Real Time Temperature Data Logger with Bluetooth

Updated: Jan 2

Learn here to create Arduino Based temperature data logger. We’ll use the DHT11 to measure temperature and Humidity, the real time clock (RTC) module to take time stamps and the SD card module to save the temperature, Humidity and Heat index data on the SD card, and Bluetooth send temperature data to HTML Java script Gauge display using android application.
