I'm 59 and this is all new to me. I have got a RPi 3B+ and ordered a DHT22 and while this is real neat, I feel a little overwhelmed. I'm not a quitter so here I am. I have a few questions.
First let me say this is being used for my research project I'm funding myself so I have to have accuracy.
Okay, can the DHT provide relative humidity? There's a difference between humidity and relative humidity. RH is a mathematical equation consisting of dew point, temperature and, humidity.
I'm studying ESD - Electro Static Discharge. You know, that nasty zap you get when you touch something after you drag feet across a carpet or the air outside is cold and dry?
So "Humidity" data is not what I want.
1. Can anyone tell me if the DHT 22 can do this?
2. Can the data be changed to Fahrenheit from Celsius?
3. I need data transmitted every five seconds or less to a remote website for monitoring. Can someone tell me how to do that too. All help would be great. If I can build the first one, I'll be able to make multiple ones later.
I have set up a MySQL database on my website already. I just gotta get everything talking to each other.
Thank you in advance for helping an old guy learn new tricks.
