Co2 measurement with Sensirion SCD41 CO2

Would a sensor like this kill battery life on a Ruuvi tag? Or is this something we could put on the wishlist for 2022?


SCD41 is a very interesting sensor, however the minimum voltage of 2.4 V and peak current of > 100 mA aren’t a good fit for a coin cell battery.

It would work better as a add-on to Ruuvi Gateway, as there’s USB power available

Yes, not many coincell driven co2 sensors out there.
I’m for the moment testing a japanese co2 beacon sensor BLE Sensor Kanki AirMier – obniz store that also have 5v from usb.
