Sensors & Devices: One DHT22 Temperature and Humidity Sensor, One Raspberry Pi There is also a menu containing settings for acceptable temperature ranges, reread intervals, how long to keep log data, email settings, email confirmation, and temperature scale. There is also the ability to clear log data. This button allows the user to take a temperature reading before the reread interval is up for when a quick read is needed. Another additional feature includes a button. This Temperature Monitor sends emails via Gmail API. This acceptable range can also be configured by the user in the GUI. The TempWatch Smart Temperature Monitor also sends a warning to the user via email if the temperature or humidity falls outside of an acceptable range. It also stores that information in a log file that can be viewed in graph form at any time. This amount of time can be configured by the user through the program itself through the use of a GUI. ![]() The TempWatch Smart Temperature Monitor takes readings from the DHT22 sensor after a specified amount of time. The TempWatch Smart Temperature Monitor displays the current temperature and humidity on the Raspberry Pi display. TempWatch Smart Temperature Monitor is only comprised of a Raspberry Pi and a DHT22 temperature and humidity sensor, but it offers plenty of features. Students: Cullen Duval, Aiden Plauche, Cade Ruttley Sensors & Devices: Weight Sensor (Quarters), Weight Sensor (Nickels), Weight Sensor (Pennies), Weight Sensor (Dimes), Raspberry Pie, Arduino Each cup will sit on a weight sensor and will be weighed and will calculate the value in each cup for the consumer to read. Each compartment will have a small cup at the bottom that the coins will fall in with easy access for the consumer to extract the coins will need. The funnel will have the coins roll down a slope and will be deposited into separate compartments based on the diameter of each coin. This will work by having a funnel that the consumer can put the coins in. Our project will give the consumer a compact way to manage the clutter of change in their cars and have an easy way to show how much change they have and provide easy extraction of the money. This made our cars cluttered and was full of wasted money that we very rarely used. As a group, one thing that we found very annoying in high school was all of the spare change that we would accumulate every time we would go out to eat with friends and teammates. Students: Thomas Wick, Andrew Posey, Garrett Sepulvado, Elizabeth Woodardįor our freshman design project, our group decided to build an automatic coin sorter with the intention of placing it in a car’s console.

Each student participant owns and maintains their own equipment, providing a mechanism for boosting hands-on learning for large numbers of students our hope is that this project-based approach will make our students more competent, confident, and innovative. The products you see here are the culmination of a year-long, project-based learning experience where the Arduino microcontroller is used for sensing and control applications. The product is targeted for use in vehicles, smartphones and tablets, household appliances, ATMs and vending machines, game controllers, industrial equipment and medical devices.Welcome to the Spring 2022 First-Year Engineering Design Expo. It thus has frequency or amplitude limitations important in customising haptic feedback for users. The TDK piezo actuator has a stimulation range between 1Hz and 1kHz. Under a load of 0.1kg, the 5N type delivers an acceleration of 5g with a rise time of 2ms while the 20N type features 15g after just 1ms. Despite compact sizes of 12.7mm x 12.7mm x 1.6mm and 26mm x 26mm x 2.4mm, respectively, the actuators can generate forces of up to 5N and 20N.Ĭompared with typical electromagnetic solutions such as eccentric rotary motors (ERMs) and linear resonant actuators (LRAs), the piezo actuator features high acceleration and force, low insertion height and short response time. The actuator is available in two types, a 5N type that achieves up to 100µm displacement and a 20N type that can achieve more than 200µm displacement. The actuator employs cymbals on both sides of the plate as levers to amplify the contraction by a factor of 15 in the z axis. 《MOTIX™ Multi-MOSFET Driver: Best-in-Class Solution for DC Motor Control》□To control up to eight half-bridges with one packaged device ![]()
