I’m not much an electronic guy (more on the software side), so I’ve the following question :
I’m trying to connect some gas sensors to my grove board to complete with my grove dust and temp. + humi. sensors.
I’ve planned to weld them to some grove cables so all my sensors are connected the same way.
Here is the list of the sensors and their specsheets :
- MQ131 (O3) - Ozone sensor : cooking-hacks.com/skin/front … MQ-131.pdf
- MG 811 (CO2) : cooking-hacks.com/skin/front … asheet.pdf
- Figaro TGS 2442 (CO) : soselectronic.com/a_info/res … GS2442.pdf
My question is : how can I wire them to a grove cable like these ones : seeedstudio.com/depot/Grove- … =98_106_57 (by removing one end of the connector).
Do I have to add a resistance somewhere ? (pretty sure I do, but which resistance ?)
Maybe someone here already did something like this ?
