ThermoDuino is a mini Arduino compatible board that consists of LM35 temperature sensor, ATMEGA328 chip, and 0.96″ OLED display. The board has been designed to measure temperature. We have used the LM35 SO8 SMD sensor which is connected to A0 analog pin of the chip, and the OLED display is connected to A4 and A5 pin of MCU. LM35 senses the temperature and the microcontroller displays the temperature value on the OLED display. CN2 connector helps to program the microcontroller using Arduino IDE and boot-loader burning. This low profile and small board can fit in a very small case. Example code will help you to display the temperature in Centigrade and Fahrenheit. It is an open-source Arduino compatible hardware and it is easy to create your own code using Arduino IDE.
The LM35 is a precision temperature sensor IC with an output voltage linearly proportional to the Centigrade temperature. We have used the SMD SO8 sensor which can directly mount on board. The device can measure temperature from –55 to +150 degrees Celsius. The voltage output of the LM35 increases by 10mV per degree Celsius in the rising temperature.
Programming the board with Arduino IDE
A new Atmega328 chip requires Boot-Loader burning before uploading the Arduino code. Follow the link for more info on Boot-loader burning and Programming.
