Sensors and Sensor Circuit Design

This course can also be taken for academic credit as ECEA 5340,

part of CU Boulder’s Master of Science in Electrical Engineering degree.

After taking this course, you will be able to:

● Understand how to specify the proper thermal, flow, or rotary sensor for taking real-time process data.

● Implement thermal 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.

● Study sensor signal noise and apply proper hardware techniques to reduce it to acceptable levels.

You will need to buy the following components to do the two course projects based on the videos

in this module. 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. Or, you may obtain the specs from the site, and purchase them elsewhere.

These are the part numbers typed out, so you can copy and paste them into the Digikey web site.

You will need one of each part. 428-3390-ND NHD-0216BZ-RN-YBW-ND 570-1229-ND A105970CT-ND

Motors and Motor Control Circuits

This course can also be taken for academic credit as ECEA 5341,

part of CU Boulder’s Master of Science in Electrical Engineering degree.

This is our second course in our specialization on Embedding Sensor and Motors.

To get the most out of this course, you should first take our first course entitled Sensors and Sensor Circuits.

Our first course gives you a tutorial on how to use the hardware and software development kit

we have chosen for the lab exercises. This second course assumes that

you already know how to use the kit. After taking this course, you will be able to:

● Understand how to specify the proper AC or DC motor for a machine design.

● Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed.

● Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software.

● Add a motor and motor control circuit into a microprocessor based development kit.

● Create hardware and firmware to process motor feedback data to a microprocessor for further evaluation.

You will need to buy the following components to do the two course projects based on the videos

in this module. 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,

Or, you may obtain the specs from the site, and purchase them elsewhere.

These are the part numbers for the above table, the lab on Motor Voltage and Current Measurement.

You can copy and paste them into the search engine on the Digikey web site.

You need one of each except for the AA batteries (N107-ND), which you would need

3. 428-3390-ND P14355-ND FQU13N10LTU-ND N107-ND 1N5393-E3/54GICT-ND RNF14FTD1K00CT-ND P0.62W-1BK-ND

These are the part numbers for the above table, so you can copy and paste them into the search engine on the Digikey web site.

You will need one of each.

Pressure, Force, Motion, and Humidity Sensors

This is our third course in our specialization on Embedding Sensor and Motors.

To get the most out of this course, you should first take our first course entitled Sensors and Sensor Circuits.

Our first course gives you a tutorial on how to use the hardware and software development kit we have chosen for the lab exercises.

This third course assumes that you already know how to use the kit. After taking this course, you will be able to:

● Understand how to specify the proper AC or DC motor for a machine design.

● Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed.

● Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software.

● Add a motor and motor control circuit into a microprocessor based development kit.

● Create hardware and firmware to process motor feedback data to a microprocessor for further evaluation. 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.

Sensor Manufacturing and Process Control

This is our fourth course in our specialization on Embedding Sensor and Motors.

To get the most out of this course, you should first take our first course entitled "Sensors and Sensor Circuits",

our second course entitled "Motor and Motor Control Circuits", and our third course entitled "Pressure,

Force, Motion, and Humidity Sensors". Our first course gives you a tutorial on how

to use the hardware and software development kit we have chosen for the lab exercises.

Our second and third courses give you three hands-on lab experiments using the kit.

This third course assumes that you already know how to use the kit.

You will learn about sensor signal characterization and manufacturing techniques and how

to optimize the accuracy of sensors. You will also learn about more advanced sensors,

proportional-integral-derivative (PID) control, and how this method is used to give

you a closed loop sensor feedback system. After taking this course, you will be able to:

● Understand how sensor manufacturers characterize and calibrate their sensors.

● Tune a PID control loop and access the PID control function of the Cypress PSoC development kit for a motor control application.

● Understand manufacturing methods used to build electro-mechanical and micro-machined sensors.

You will need to buy the following components to do the two course projects based on the videos

in this module. 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. Or, you may obtain the specs from the site, and purchase them elsewhere.

All are quantity one except for N107-ND where you need three, and 493-15371-ND where
