I love sensors. Measure all the things! Home power generation/consumption, air quality, CO2, airplanes flying overhead, infrared, ultraviolet, RF… yah.
So here’s the latest, which I’m immediately adding to the “you should buy” list:

That’s the WeatherFlow Tempest Weather System, and it’s awesome. Briefly:
- Smartphone and web-based displays
- Simple network protocol, so there’s lots of open source to capture data
- Innovative, clever sensors – ultrasonics for wind speed and direction, piezo for rainfall. No moving parts!
- Solar powered
- Works with or without the internet
- Also has cool stuff like a lightning sensor (useless in San Diego)
- Calibrated to lux and watts per square meter
- Reports UV levels too
- Precise temp/humidity of course.
Here’s a picture from the vendor:

Basically a does-everything solution. I found it via this TechHive review and got one ordered. It took a few weeks to arrive, but having just installed it, like I say, I’m already a fan. You have to pay more ($329) for the better tech, but having bought and had fail any number of $50 to $100 ‘weather stations,’ I’m ready to buy it once and enjoy it.
You can see my data right here on the web. Buy your own from the vendor here.
