Analog Interfacing with Sensors for Embedded Systems
The use of sensors in embedded applications has become widespread and is growing rapidly. Systems from industrial automation to medical to consumer devices utilize sensors for fundamental measurements in basic control loops and to detect environmental conditions allowing for advanced functionality.
Sensor outputs include mV, mA, resistance, and capacitance. Each type presents unique issues when interfacing with an embedded microcontroller. This webinar discusses techniques for interfacing sensors to an embedded microcontroller, including noise bandwidth reduction with on-chip filters and elimination of offset and drift errors using correlated double sampling. It also discusses the signal path and applications for ultrasonic, ambient light, and accelerometers.
