    Default Anyone use Adafruit sensors in home projects?

    Looking to build a network of temperature sensors around the house, because, of course.
    Seems like adafruit has lots of amazing sensors. I think you need a raspberry pi or similar to run them.
    This type of sensor:
    https://www.adafruit.com/product/2652
    Or
    https://www.adafruit.com/product/3251
    Anyone do this? Longer term, I am considering using a raspberry pi as my thermostat with some if-then type logic based on interior and exterior temperatures.

    I love adafruit so much. Also https://www.sparkfun.com/ has lots of cool modules as well.

    I use esp8266 based modules with DHT22 temp/humidity sensors.
    Cheap, built-in wifi, and they speak MQTT.

    Much cheaper on Amazon, also a Western Canada site has good prices as well

    I need to learn more about this stuff. My wife has done some cool things with a raspberry pi, but I've stayed out of her way mostly. She does some data analysis type coding for work, so she's more fluent than me. I haven't coded since university.

    If I'm looking to distribute a bunch of these sensors around the property, I think I need to make sure each node has pretty cheap parts.

    Want to get the network of temperature sensors working before I hack up my own HVAC control system.

    Actually with adafruit you really should check solarbotics.

    Local distributor - often way cheaper.

    Ds18b20 for plain temp - watch the dht11 it doesn't always play nice.

    I have several different types of sensors etc. The nice thing is they all talk to Home Assistant so regardless of type/technology it's all available in one place.
    Seems my deck sensor might have stopped reporting. Edit, nope its 19 in the sun on the deck.

    Really depends how you want to go about things. If you're handy with electronics then you can mcgiver your own with something like an arduino and some random shields of your choosing. Coding wise you don't really need to know much since it's pretty plug and play... Most of these things have all the code already written for you.

    There are commercial products that already do what you're looking to build so it just depends on what you're aiming to get out of this. Here's an example product: https://www.ubibot.io/ubibot-ws1/

    HVAC wise residential furnaces are pretty shit when it comes to trying to control them since they typically are only on or off. There's usually no ability to light selective burners or to actually really control the damn things. PID control is really the thing that should be put into place for temperature control but you'd need some fancy furnace for that to work...

    Ubibot looks cool, but $80 usd/ea. Really hoping I CN get lower unit pricing because this project is cooler with 6-10 sensors.

    Those look similar to these:
    https://store.wirelesstag.net/collections/all Bit cheaper.

    I have 5 of them, plus the tag manager. Range is good, I have one in the deep freeze, one in the fridge. Also the one in the bedroom is on the 2nd floor, tag mgr in the basement, no issues.

    I have no particularly practical reason. Basically just a hobby project.

    I think data is neat, and I have essentially zero hobbies.

    This looks cool, just placed the order. Will report back when they arrive. Look more like a complete product than the adafruit sensors, which would have needed some pretty serious assembly to be as functional.

    The adafruit stuff is "simple" until you have a problem and then you need an oscilloscope. Most people follow by rote the instructions they find online without really knowing what they are doing in terms of the sensors. However if you're trying to build something different from standard then yeah you're wadding into more the side of the electronics hobbyist. That's fine if that's what you want to do but you're really going to need a soldering iron, a multi meter and possibly an oscilloscope.

    Yeah, I suspect that the fact that I got confused and frustrated just looking at the catalog means they are not for me. The "wireless tag" website makes it all sound pretty seamless. We shall see what I can do with them when they arrive.

    Received the Wireless Sensor tags this morning. Ordered in evening June 4th, got them morning July 2, that's probably about what I expected, although I'm spoiled by Amazon Prime for everything else.

    Got the first two set up just to test the system out. Dead easy. Will be positinging the three otehrs around the property and messing with it through the next few days.

    Yeah, they're quite easy, and the range is pretty surprising, especially when 2 of mine are inside metal fridge/freezers

    Better than @rage2 data presentations?

    Almost scintillating.

    I'd say you're in a classic A-wave behaviour that you can ride out before shorting your spread to cover your ok board potato.
