My company has designed a Module with a gas sensor embedded and the Module has a 3.3V level UART digital signal as output. How do we do to use/connect to the atmosphere cloud ? Do we need to use extra Bluetooth/WiFi module? If so, then what kind of BT/WiFi module should we use? Thank you very much!
@walle - From your description, it sounds like your sensor module could use the UART element to get your data to the cloud. We also support sensor companies writing their own EELs if you need more flexibility. See the example here - https://github.com/atmosphereiot/eel-builder/blob/master/examples/my_first_eel/README.md
ESP32 is a good starting point for any project. It has both BLE and WiFi and lots of UART options, but you can check the developer hub - https://developer.atmosphereiot.com/ for additional options.
