General approach to sensors

Tue Oct 10, 2017 5:28 am

Hi

I'm quite new to my PI3 but I have 15 years of experience with frontend development for web, so the programming part seems easy to me. However, AFAIK it's possible to use almost all types of sensors, but is there any kind of general guide for understanding how to connect sensors?

E.g. I have this sensor for temperature and humidity https://erelement.com/sensors/dht11 - but I have no idea where to stick those pins :D
I can see the datasheet for that specific sensor here https://cdn-shop.adafruit.com/datasheets/DHT22.pdf - but I guess my basic electronic skills are lacking ;)

Great resources for introduction to sensors / electronics and connection using e.g. breadboards?

Thanks

Try:

https://projects.raspberrypi.org/en/pro ... -computing

It's very basic, but maybe worth a look.

Also the worksheets here: https://camjam.me/?page_id=623

In general, there is no general approach. Other than to read the datasheet for the device in question and then implement a solution using the tools provided by the RPi.

Alternatively, use an internet search for "Raspbian + <name_of_your_sensor>" to see if someone has already solved the problem.

learn.adafruit.com has thousands of tutorials, many regarding the Pi and sensors, and often accompanied with Python libraries.
