Cheap wifi temperature logger

[jklondon]

Hi - looking to create a small cheap temperature logger that streams to the internet.

What components can I use to create this, ideally no soldering if possible?

Thanks

Common one is a DS18B20. You can use a solderless breadboard and some dupont wires to connect that to 3V3, GND and GPIO04 on your RPi.

DHT22 with python and SQLite (or MySQL)

I use a couple of DS18B20 sensors on a Pi2, recording to a SQLite database. Then a cgi script to present and graph the data over the web.

It was all built and tested on a PiZero if you want to go smaller.

This is the instruction I followed

Thanks - DHT22 seems way forward - found a good tutorial here https://www.youtube.com/watch?v=IHTnU1T8ETk although if someone knows a better one for beginner pls shout. I assume this could work on pi zero if I can find one!

I'm sure that will work on the PiZero, but it doesn't seem to show how to stream it to the web.

The link I gave above logs the temperature to a SQLite database.

at the bottom of the page is another link which shows you how to read the database over the web.
