Radio sensors for weather data

Sun Mar 11, 2018 9:49 am

Hi guys, sorry for the bad, but I wanted to understand something.
I have a weather station WH1080SE with monitor for the vision of the data, the sensors of the station converse I think in 433mhz.
I connected a raspberry pi3 to the monitor where I installed Sandaysoft's CumulusMX (software for data management) and load it all on an altervista site (meteobg.altervista.org) where I applied a Brian Underdown Weather34 template. (https://weather34.com/homeweatherstation/)
I wanted to add other sensors, for example, air quality and UV rays and transmit the data of the new sensors to the raspberry by radio. (http://www.ebay.com/itm/like/171284863309) and then, somehow that I still do not know, on altervista.
It's possible?
Do you need an external radio module and an internal receiver module to install on the raspberry? (the rasp is indoor home)
Does the external module need power? to come ?
Sorry but I'm an architect and I have not studied electronics.
It's already a miracle that I managed a fare ...
thanks
tommy

Just use Google for it.

As I understand these articles your device uses 433.92MHz FSK modulation. There are a lot of receivers/transceives that you can use now and you can find cheap modules. The problem is to write a software that decodes the protocol of this device and this could be a problem for you if you could not find something that already works.

I have done similar thing but in my cases it was OOK modulation.

ok, I need a bit of time to metabolize everything
but, without interfering with the wh1080 station that I leave alone, can I not create an independent communication between the new outdoor sensors and the indoor raspberry?
another thing that is not clear to me, the sensors that I put outside need a new raspberry that will also be outside?

Everything is possible if you put enough effort and money :).
I did it but with other sensors. In fact a protocol for each such sensor is unique.
Basically in my project I can receive temperature and humidity from following sensors:
  • Ambient Weather F007TH
  • AcuRite 00592TXR/06002RM
  • LaCrosse TX7U (probably TX3/TX6 may also work).
This is what I have implemented so far. I have sensors outside my house but most of them are inside (in rooms, in garage,...)
See https://github.com/alex-konshin/f007th-rpi
See also my thread here in forum: viewtopic.php?f=37&t=173023
Please note that my implementation does not provide final and complete solution. This is kind of building block that you can use to build your own solution.

thanks for the answers, I have just started to enter the forest of the internet with a machete to make my way through the innumerable information.
I came across this esp8266 module (https://luftdaten.info/), which could mount an aqi sensor and transmit (maybe) data to my raspberry.
It's possible ?
Could it also be powered by a small solar panel or simple batteries? (3.3V)
Meanwhile, I continue to make my way through the lush vegetation ...

You'll find the Wemos D1 Mini is a good entry level ESP microcontroller for GBP£3.50.

There's even some ready built sensor boards for it.

I have the following
• WMR86 Weather Station Console
• Wind Sensor (WGR800)
• Temperature and Humidity Sensor (THGR800)
• Rain Gauge (PCR800)

I bought a NooElec NESDR Mini SDR & DVB-T USB Stick (_http://www.nooelec.com/store/nesdr-mini-rtl2832-r820t.html)
then used software to read the 433 signal

_https://github.com/merbanan/rtl_433

works fine! gets all the data.
I then re-transmit the data via MQTT to my Home Assistant
