CO₂ sensor Forum Discussions
Hi everyone
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.
Thanks

Hello,
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?
Best regards,
Nakamura
How to use the XENSIV PAS CO2 Sensor with a PLC ?
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 products
Show Less1、移植程序我已经从 https://github.com/Infineon/sensor-xensiv-pasco2下载
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.....
4、
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

1、您好 ,现在计划 使用 EVAL_PASCO2_MINIBOARD ,Infineon官网有 原理图SCH等
2、但是没有发现 EVAL_PASCO2_MINIBOARD PCB layout的Ad文件 和 EVAL_PASCO2_SENSOR2GO的 PCB layout文件和软件程序;我想layout一个PCB,EVAL_PASCO2_MINIBOARD 直接对插就可以了,现在不知道MINI BOARD 的插针具体数据
3、UM_XENSIV_PAS_CO2_miniboard-UserManual-v01_01-EN 这个是PSOC6+EVAL_PASCO2_MINIBOARD ,请问程序在哪儿下载呀 ?

Show LessHi,
Is the any CO2 sensor which can covers 0~50000ppm with accuracy of +/-10ppm? Thanks.
Dear Community,
I am wondering if it's possible to significantly improve the response time of the CO2 sensor by for example removing the membrane covering the sensor casing (white dot in image below).
What is the purpose of this membrane? Protect from dirt and moisture? If the sensor would be used in an otherwise "safe", i.e. dry and clean environment, would one need the membrane? I am aware that the warranty would be void when using the sensor in this way, but we need a much faster response than what the sensor can do with the current setup and this sensors speed is certainly not limited by the measurement principle.
I hope someone can help!
Thanks,
Johannes
Show LessCan anyone tell me, PASCO2V01 metal shell QRcode, how to use QR what information can be obtained.
Hi, there
Just for your information, I posted a code sample for PSoC 4 (CY8CKIT-044)
