In this a bit more extensive project we deal with several factors on the subject of indoor climate. We will measure the temperature, humidity and air pressure, saving maximum and minimum values of our measurements and show it on a TFT display.
Simple indoor climate monitoring with an Arduino, BMP085, RTC, DHT11
The Tiny RTC breakout board with the DS1307 real time clock chip from Maxim Integrated Products allows time-and date-dependent circuits with the Arduino or other microprocessor environments. Data logger, timer or alarm clock are just some example applications. In addition, the board has an ATMEL 24C32 EEPROM chip with 32 Kbits memory and still the ability to add a separate temperature sensor (DS18B20).
