I did develop some professional temperature measurement equipment with 24 bit Analog Devices ADCs, ratiometric measurement and high precision PT1000 sensors and I was happy to get 0.1°C accuracy ...

The temperature sensor is built using an NTC 10k thermistor, which changes its resistance in response to changes in temperature. The resistance of the thermistor is measured using the Arduino's analog ...

I have done e similar project with Arduino and tow sensors – BMP085 for atmospheric pressure and the other one DHT for the humidity levels with both sensors measuring temperature. Soon I’ll ...

You also need to select the transistor by the type of fan that you use. In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 ...

Abstract: The project is named as “DIGITALLY SENSE HEART RATE AND BODY TEMPERATURE USING ARDUINO”. With the development of technology, in this project we can digitally sensing body temperature and ...
