This sensational and very easy to handle app transforms your iPhone or iPodTouch into a real thermometer device. You can practically measure environmental temperature from -20°C up to 140°C or 0°F up to 320°F. You may switch between Celcius and Fahrenheit on the fly within the application. The temperature is displayed on a big analog instrument.

To operate this app you need some additional hardware option that you have to connect to the headphone connector via a 4 pin plug. All you have to do in this little DIY project is to connect a NTC 10hOhm thermistor, a 0.1uF cap and a 180Ohm resistor to the plug. The circuit is shown within the help page of the app.


To run this app a DIY hardware option is required as described above

This app is only for experimental, hobby and educational use. This is not a precise approved instrument and may not be used to perform serious temperature measurements and human use.
