Sensor wise, I have three WioNodes (https://www.seeedstudio.com/Wio-Node.html). Connected to them I have:
On #1 -- a Multichannel gas sensor ( https://www.seeedstudio.com/Grove-Multichannel-Gas-Sensor.html) and a dust sensor ( https://www.seeedstudio.com/Grove-Dust-Sensor-PPD42NS.html) On #2 -- A Temp/Humidity/Barometer Sensor( https://www.seeedstudio.com/Grove-BME280-Environmental-Sensor-Temperature-Humidity-Barometer.html On #3 -- A Temp/Humidty sensor ( https://wiki.seeedstudio.com/Grove-TempAndHumi_Sensor-SHT31/) I found a nice 3d case design for the WioNode and a slightly modified one for the sensors. ( think this is the case : https://www.tinkercad.com/things/dRPiUfLRj3w-wio-node-case) What's nice about these is that it's just a simple process to set up: 1) Put in case 2) Plug in cables 3) onboard to wifi 4) select sensors in app 5) Click button and firmware is built and deployed (assuming you use supported sensors) Then data can be accessed via REST call (which you can actually do via the app... it gives you the full REST call and a button for getting current values) Easy Peazy. Some sensors don't play together (the WioNode has two different configurations on the two plugs... so it just depends on which sensors and which interface...) You can add a "grove hub" to a side if you wish, but given the cost, I just went with an extra WioNode for what I needed. It also gives me the option of adding some other sensors (like the AQI sensor..)
