K30 CO2 Sensor Lockup Solutions When Using Arduino

Customers using the Senseair K30 1% and 3% CO2 sensors with the Arduino MCU and the supported library occasionally see “lockup” of the sensor.

It appears that the sensor sends negative data and quits working. After unplugging the sensor from power momentarily, it works again.This seems to be a random problem.

Fortunately, we have been able to recreate the problem, and have several solutions here:
