SCD30 Gas Sensor not powering on

Sensors Environmental

Hi,

I purchased 6 gas sensors. However, 3 of them cannot power on with a USB 5V while the other 3 can (orange LED glowing). I also encountered the same issue with some of the SCD30 sensors not powering on from a purchase about 2 weeks ago. Has anyone had the same problem with SCD30? Or is there any procedure that needs to be done to power up the sensor robustly? Thanks

It might be correct. The SCD30 has non-volatile memory. When set to Continuous measurement the status is saved in non-volatile memory . When the sensor is powered down while continuous measurement mode is active SCD30 will measure continuously after re-powering without sending the measurement command.

Thank you so much this works!
