The Raspberry Pi is a single board computer aimed at encouraging students and hobbyists to experiment with programming. It has a GPIO connector for controlling external devices,

 

Reading analogue signals is very useful in a multitude of applications. For example many sensors output an analogue signal that is proportional to the stimuli being measured like temperature, light, pressure and sound level. The Raspberry Pi GPIO does not have any Analogue to Digital Converters (ADC) to allow this to be measured directly. The projects in this book are all about using an external ADC and then interfacing to a number of sensors to make measurements.

 

Project 1 – Measuring Voltage

Project 2 – Temperature Measurement Using the TMP36

Project 3 – Resistance Measurement

Project 4 – Measuring Temperature Using a Thermistor

Project 5 – Measuring Light Level Using a Light Dependent Resistor Project 6 – Measuring Force Using a Force Sensing Resistor

Project 7 – Measuring Voltage of a Car Battery

Project 8 – Measuring Low Voltages

Project 9 – Measuring Power Using a Current Clamp

Project 10 – Measuring Sound Level Using a Microphone
