What and why?
Since I got an RTL-SDR radio receiver my interest in 433MHz stuff reignited and there's loads of things to do with it that are fun and even can be useful. This page will be used to document some of the things I want to do.
Test setup
Arduino with 433MHz transmitter.
Todo
- Test transmitter (check with RTL-SDR)
Emulating external sensor for weather stations
I acquired two weather stations in a thrift store that seem to be working but are missing their external sensors. The idea is to emulate these sensors with a 433MHz transmitter coupled with a microcontroller or SBC. Data can be gathered from an online weather service or an actual sensor.
The devices
ISY IWS-4100
Missing sensor: temperature and humidity
Oregon Scientific RMR112
Missing sensor: temperature. Some compatible sensors: THN128, THR128, THC268.
