Publisher's Synopsis
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 VoltageProject 2 - Temperature Measurement Using the TMP36Project 3 - Resistance MeasurementProject 4 - Measuring Temperature Using a ThermistorProject 5 - Measuring Light Level Using a Light Dependent ResistorProject 6 - Measuring Force Using a Force Sensing ResistorProject 7 - Measuring Voltage of a Car BatteryProject 8 - Measuring Low VoltagesProject 9 - Measuring Power Using a Current ClampProject 10 - Measuring Sound Level Using a Microphone
