Intro to Sensors

Class Information

Format: 2 weekday evening sessions, 2 hours each

Most Recently Taught: July 18 & 25, 2012

Instructors: Christalee Bieber & Daniel Bergey

Description: Sensors help us hear what the world around us has to say. In this class you will build circuits that measure temperature, light, and motion. We will cover voltage and current control, and use transistors and op-amps (amplifiers) to drive LEDs and lightbulbs. Our examples will all be analog, but the techniques are also useful for connecting sensors to microcontrollers.

Bring your own project ideas, or use ours to start. Each session will have time to work on your project with help from instructors. No electronics background is required. All ages welcome; students 13 and under should be accompanied by an adult.

Learning Objectives

Upon completing this course, students should be capable of:

Class 1 Outline (PDF)

Class 1 Handout (PDF)

Class 2 Outline (PDF)

Class 2 Handout (PDF)

In addition to the handouts, datasheets for each major component were made available for students to consult during class.
