CO₂ sensor Forum Discussions
I am using PASCO2 for our portable instrument product.
we have concerns of the calibration mechanism.
may I the know the trigger condition of ABOC ?
How does ABOC work? does it take 1week to correct the baseline? for portable instruments, if we don't switch on the power, how does it get the correction baseline?
when we purchase the PASCO2 should we do the calibration by ourselves? thanks.Show Less
Regarding PAS CO2 sensor spec, please let me know the difference between "Storage temperature" and "Storage time during transport".
Which specification will be applied after incorporating into the product?
Hi~ Muhammad Nanda
I made new Community thread as you suggested.
I think it is better idea. I agreed completely.
Above sample code, I tried to make button handler in it.
But it doesn't work properly. Because It seems that former thread has own priority. So that other event handler seems to be ignored.
Do you have any idea to solve that issue?
The datasheet states that the lifetime of the PAS CO2 sensor is 10 years. Is it necessary to have a measurement operation condition of once per minute in order to achieve this time (10 years)?
If it is necessary, would extending the lifetime to more than 10 years be possible by changing the measurement frequency to once every two minutes?
Could you please tell me the size of the space that can be measured by the one PAS CO2 sensor?
For example, 100㎥, 500㎥...
Any advice would be appreciated.
Regarding the datasheet, the mesurement range os the PAS CO2 is 0 to 32000ppm and the accuracy of 400-5000ppm is -30ppm-3%～+30ppm+3%.
Is it possible to show the accuracy under 400ppm because our customer would like to measure under 400ppm?
May I ask what material is the white film on the air inlet of your photoacoustic pool? Does your company provide this material for sale, or can you tell me which company has similar productsShow Less
2、是在 MCU 上运行，不带操作系统，使用I2C 接口
按照文档所说，和I2C 有关的 接口需要是实现，但是，CO2的 I2C 地址是多少呀，在程序里或者注释并没有发现.....
以上是 在 使用Infineon芯片的 调用例程，如果不使用 Infineon的芯片，应该如何移植和调用呢 ？有更底层的函数吗？就是I2C 通讯接口吗 ？这个是类linux的，但是我这没有操作系统呀 ，而且不具备cy_hal 库
result = xensiv_pasco2_mtb_read(&xensiv_pasco2, DEFAULT_PRESSURE_REF_HPA, &ppm);，尤其这句，循环调用，是I2C 读取函数吗？好像不是，有个 DEFAULT_PRESSURE_REF_HPA 这个参数；
能否更明白说明从I2C 地址的那个寄存器地址读取的数据吗 ？谢谢
