Temperature and Humidity with Arduino

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.

Temperature and Humidity with Arduino

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.

Temperature and Humidity with Arduino

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.

DHT11 Aosong RH and Temp Sensor Circuit

“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.”

Amateurfunkbasteln – Amateur Radio Crafts and Electronics

Amateur radio is a technical hobby. The attraction? To cover long distances with a low power radio to talk with other people, learn about their countries and cultures.

Amateurfunkbasteln – Amateur Radio Crafts and Electronics

But amateur radio also means tinker devices themselves, solder, apply electronics and learn something. In this sense, it can be a preparation for a technical career or even an engineering degree.

A Data Logger that records Slowly varying parameters, such as the temperature or decreasing the voltage of a battery. This copy records up to four measurements on parallel and saves it on a EEPROM.

Four Channel Data Logger - Amateurfunkbasteln

Four Channel Data Logger

It measures self-sufficient – without a PC – analog voltages (0-5V), it digitizes and stores the numerical value obtained in a separate memory. Later, after the measuring and recording phase, passes the data logger its information to the PC.

Sleeping Beauty – Arduino Compatible ATmega1284p board

The Sleeping Beauty is an Arduino Compatible board using an ATmega1284p.  The board was designed by Wayne Chu.  The size and function are the same as an Arduino UNO r3.

It has all the necessary components of an Arduino compatible UNO board but adds several devices useful for software development and education. These are briefly described below:
