Prerequisites

Can you reproduce the problem reliably? Yes

Description: Hi ,

I am trying to use the example serial-alarm from arduino-pas-co2-sensor-master library(version 2.0.0). But in serial terminal, getting error code 1 and 7. Attached is the snapshots for your reference. Can you please check and let me know.

Steps to Reproduce:

  1. Arduino uno board is connected PAS-CO2 sensor.
  2. 12 volt and 3.3 v for the sensor is taken from sensor2go kit.
  3. Open the code example serial-alarm.ino available in Arduino\libraries\arduino-pas-co2-sensor-master\examples\serial-alarm.
  4. Modified I2C_FREQ_HZ value 100000 and interrupt_pin to 3 in serial-alarm.ino
  5. Changed the PASCO2_INO_INT macro value to 3 from 0xFF in pas-co2-platf-ino.hpp since we are using Pin #3 for interrupt.
  6. In pas-co2-serial-ino.hpp file and in startMeasure function, the value of alarmTh is modified to 24000 from 0
  7. Run the code example serial-alarm.ino

Expected Result:

A non zero co2 ppm value.

Actual Result:

2

Frequency (1/1, 1/50, 1/100): 100

Build/Commit:

Please specify the release, like 1.4.1. If there is no release, give us the commit for the code you used. 2.0.0

Target:

Arduino uno board

Host OS and Version:

Windows 64 bit

Environment Arduino ide

THANKS!

Hi @Anandaramashetty,

The new release https://github.com/Infineon/arduino-pas-co2-sensor/releases/tag/v2.1.0 might solve partially the measuring mismatch issues.
