Pressure, Force, Motion, and Humidity Sensors

Description

After taking this course, you will be able to:
● Understand how to specify the proper pressure, force, strain, position, motion, acceleration, occupancy, and humidity sensors for taking real-time process data.
● Implement these sensors into an embedded system in both hardware and software.
● Add the sensor and sensor interface into a microprocessor based development kit.
● Create hardware and firmware to process sensor signals and feed data to a microprocessor for further evaluation.

In this course you will build the circuit from Video 7 (Lab Exercise on strain gauges), Module 2 (Force and Strain Sensors and Touch Screens), and use it to make screen shots of the timing of the switch. If you haven’t already wired up the system and written all the software per the instructions of Video 7, please do so now.

You will need to buy the following components to complete this assignment. Note that if you have already purchased the PSOC 5LP PROTOTYPING KIT, you do not need to buy it again.

These parts may be purchased off the Digikey web site, www. Digikey.com. One part needs to be purchased off the Sparkfun website www.sparkfun.com. Or, you may obtain the specs from the site, and purchase them elsewhere.
