Converting Analog Output Current of a temperature Sensor

Good day to all,

Please I need you guide and support on how to connect the analog output signal of a temperature sensor to my microcontroller. I already have a board with Attiny2313 on it. I can send and receive data from this board to the computer. What I want to do now is to connect the analog output signal of a temperature sensor to this Attiny2313 and then display the equivalent temperature value on the computer. The analog output signal of the sensor has a range of 4mA to 20mA, this is equal to the temperature value of 50C to 400C.( that is minimum temperature value is 4mA=50C and maximum value is 20mA=400C.I would be very grateful if somebody can put me through on how to modify my circuit in order to achieve this result. What type of components do I need to add to my circuit. Thank you for the usual support.

Best regards.

Hello John,

Convert your Analog signal to Digital signal, use a ADC circuit or chip for conversion

Read this digital on Interrupt pin of your Microcontroller. You can find many examples of it on GOOGLE. :)

All the best.
