Come join us at TheLab.ms Education Center in Plano TX to learn about the sensors you can use with the Arduino and other micro-controllers. In this class we will be covering the following:
About Sensors (http://bit.ly/2gPeQGS) (3:03) This is a short introduction to the world of sensors. I enumerate the sensors that I'll be showing you in this section, and then get straight into it!
Measuring Light (8:29) In this lecture, you will learn about how to detect and measure light using a photo-resistor. You will also learn about a common technique in electronics, the voltage divider. You will put all this in practice in a simple Arduino circuit.
Temperature and humidity (http://bit.ly/2ghURR2) (7:09) In this presentation you will learn how to measure temperature and humidity. To do this, we will use a sensor from the DHT family of temperature and humidity sensors. You will also learn about the dielectric property of certain materials, and of how to include an external software library to your Arduino sketch.
Barometric pressure sensors (http://bit.ly/2fUes8x) (7:11) This presentation discusses barometric pressure and how you can measure it with the BPM085 sensor. You will also learn about the I2C communications interface that this sensor uses to communicate with the Arduino. PLEASE NOTE: A new sensor, BMP180, has been release as a drop-in replacement of the BPM085. The new device is a drop-in replacement of the old, so you can use the exact same connections schematic and library as described in this presentation. Also, Adafruit has released a new version of the library, compatible with both BPM085 and BPM180 with new useful features; I will be creating a new presentation showing how to use the new library.
Infrared motion sensors (http://bit.ly/2fPVfdg) (9:04) In this presentation, we will connect a passive infrared sensor to our Arduino, calibrate it, and turn an LED on every time motion is detected. We also discuss the different technologies used to detect motion. Parts Needed:
Arduino UNO (http://amzn.to/2guHM9Z) photoresistor (http://amzn.to/2hBnMj0) The DHT22 or DHT11 sensor. (http://amzn.to/2guFaJ4) The BPM085 barometric pressure sensor. (http://amzn.to/2h3oDNa) HC-SR501 passive infrared sensor. (http://amzn.to/2gHXuvX) Course work for this class comes from Arduino Step By Step (http://goo.gl/5Uv71ft) which has over 20 hours of content in 110 lectures. These classes are designed for anyone interested in learning electronic design and C programming. No experience is required. Access to the course material is free at our meetups. If you wish to access the material outside the meetup see our coupons page to get a discount from our sponsor (http://www.hackerspacetech.com/pages/coupons.html).
The Arduino Class videos (https://www.youtube.com/playlist?list=PLGkwJjX14K5YEeVpuoVvxOYb-y8BDduKz)will be available for remote viewing during the time of the meetup.
