Wow SenseAit S8 already dead?

Well it’s been working ok for a few months, and now for whatever reason I no longer get a CO2 reading.

Nothing in my setup has changed, I have a constant power supply that was working fine , and have tried resetting a few times with no results, what is the lifespan of this component supposed to be?
Very sad.

@Nomad this is highly unusual. We have 100s of the S8 deployed since years and virtual not a single one died. Does it still blink from time to time?

No lights coming from the Senseair.

I would take it out of circuit and test with 5v on G+ pin and ground on G0 pin. If it starts lighting up, the sensor is not the issue.
