Interface an Arduino to electronic sensors to make these basic measurements. These are needed in your Garage, Basement, Attic or Loft; The Living Room too, Humidity and Temperature have an impact on your health and also the life of the furniture and wood construction material too.
This device will show air temperature in C and F, and % Humidity on an LCD display. A DHT11 Humidity and Temperature Sensor converts the Real world Parameters of Temp/RH into readable Volts for the Arduino A/D section.
Digital output temperature and humidity sensor DHT11
DHT11 from Aosong is a digital temperature and humidity sensor. A type of composite Sensor that contains a calibrated digital signal output of the temperature and humidity.
“Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology, to ensure that the product has high reliability and excellent long-term stability. The sensor includes a resistive sense of wet components and an NTC temperature measurement devices, and connected with a high-performance 8-bit microcontroller.”
