How do you built your sensor?

[RemoPro]

You list the components but not how to connect these to build a sensor myself

[sighmon]

@RemoPro I've added instructions here: https://github.com/sighmon/ios-ble-co2-sensor#assembly

Let me know if you'd like extra information.

Does the sensor function with Bluetooth everywhere after the initial setup? So I can use it if I have no wifi

[sighmon]

@RemoPro Yes it works without an internet connection. It only needs WiFi if you'd like to upload your readings to an influxdb cloud account.

Great, how much is the total hardware cost?

[sighmon]

@RemoPro Depends where you live - for me in Australia ~AUD$150 without the battery and charger.

[RemoPro]

I only need the battery charger when I want to use an battery right?

[sighmon]

@RemoPro Correct. Else connecting it to a USB-C power source will work.
