Qwiic Breakout Board for the Infineon XENSIV PAS CO2 Sensor.

SparkFun Photoacoustic Spectroscopy CO2 Sensor - PASCO2V01 (Qwiic)

SparkFun Photoacoustic Spectroscopy CO2 Sensor - PASCO2V01 (Qwiic) (SEN-22956)

The SparkFun Photoacoustic Spectroscopy CO₂ Sensor features the XENSIV^™ PASCO2V01 sensor package from Infineon^©. The sensor measures highly-accurate CO₂ data in direct parts-per-million (ppm) format over I²C, UART and PWM. The PAS CO2 employs a photoacoustic spectroscopy measurement system that combines narrow-band filtered IR light and a highly sensitive microphone inside the sensing cavity to measure CO₂ concentrations from 0 to 32,000 ppm with a best accuracy of ±(30ppm + 3%) when reading between 400 ppm and 5,000 ppm. It also includes a microcontroller that converts the data into direct ppm readout over any of the three communication interfaces. The IR emitter on the PAS CO2 requires a 12V supply so the board includes a AP3012 boost regulator with a series of decoupling capacitors to output a clean 12V from the 3.3V sourced through a Qwiic connection.

sparkfun_qwiic_co2_sensor_xensiv_pas's Issues

Difficulty of submitting comment or issue with the new format

Subject of the issue

Although the new format allows ADVANCED users to actually do something about problems, it needlessly complicates things for the NOVICE user.

Your workbench

Firefox on OSX

Steps to reproduce

Try to submit an issue WITHOUT being logged into GitHub

Expected behavior

There should be a way to submit an issue and/or ccomment WITHOUT having to have a GitHub account. Although I can see the requirement to have a SparkFun account to add an issue and/or comment on the "Getting Started" guides for SparkFun products, layering on the need for a GitHub account will scare off MANY "novice" users!

Compare the "Comments" submission for the old format of "Getting Started" guides, e.g. https://learn.sparkfun.com/tutorials/sparkfun-gps-rtk-dead-reckoning-zed-f9r-hookup-guide

BTW, I DO like the idea of allowing "more advanced" users the ability to make corrections/additions, and CAN see the need to have the GitHub login for that purpose.

Actual behavior

Excess B.S./"red tape" to be able to submit a comment/issue.

Missing item in "Hardware Overview"

Subject of the issue

In the "Hardware Overview", under "Solder Jumpers", the I2C jumper is listed, but there's no explaination of what it does.

Your workbench

Firefox on OSX

Steps to reproduce

Read the "Solder Jumpers" section of the Guide.

Expected behavior

The purpose of each of the four jumpers, PWR, PSEL, PWM, and I2C should have its own bullet describing what it does.

Actual behavior

The bullet points for PWR, PSEL, and PWM are present, but the I2C is missing.
Although it's pretty typical that cutting the traces for the I2C disables the I2C pullup resistors, I don't have time right now to go through the schematic and verify it (not with the overhead of the new "comment" format), so won't submit a correction myself.

Problem with format of Guides

Subject of the issue

Problem with overall format for Guides

Your workbench

Firefox web browser on OSX

Steps to reproduce

Look through the original guide by clicking on the "Getting Started" guide on https://www.sparkfun.com/products/22956

Expected behavior

A clear explaination of HOW to get to the next page after the "background info" stuff.

Actual behavior

FORCES first time user of this new Guide format to GUESS how to get to actual info. Go look at one of the older "Getting Started" guides -- it's VERY CLEAR how to get to the next page!

For example, https://learn.sparkfun.com/tutorials/sparkfun-gps-rtk-dead-reckoning-zed-f9r-hookup-guide
It's BLATANTLY CLEAR how to get to the next page!
