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 DHT11 is a simple and inexpensive temperature and humidity sensor, which is ideal for small projects with the Arduino, in which it does not depend on a high degree of accuracy of the measurements. It should be used for indoor measurements.
DHT11 – Temperature and Humidity Sensor
Sensors, like the DHT11, are virtually the senses in the world of microcontrollers. With them you can observe, for example, environmental influences, and possibly respond. In this case we deal with the temperature and humidity measurement and therefore we have almost a small weather station.
