Humidity Display of Date, Time and Temperature Using Arduino

Humidity Display of Date Time and Temperature


Have you ever wanted to make your own interface that can display the time, date, along with the temperature and the humidity? Well it’s a lot easier than you’d think.

A few important components are needed, as shown below.

Arduino Uno/NanoHumidity Display of Date Time and TemperatureFirstly we will be needing a micro controller. I used an Arduino Uno for my project but an Arduino Nano will also have enough pins.Humidity Display of Date Time and Temperature DHT11

The DHT11 is a very affordable digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air. The timing of the readings is crucial, as it is advisable to take reading every 2 seconds.

There is a small point to keep in mind. After setting the time once, make sure you comment that line, and compile again. This way, the RTC will keep track of the time, and the time will not set to whatever you compiled it to be earlier.


The DS3231 is an RTC module, same as the commonly used DS1307 module. It is considerably cheap and far more accurate that its DS1307 counterpart. It contains an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted.
