I need to use an I2C NDIR sensor to detect CH4 at typical atmospheric concentrations.
DFRobot doesn’t actually sell such a sensor, but I believe I can assemble a solution from off-the-shelf components. My questions:
- Looking at DFRobot’s O2 Sensor or the related line of products (note that DFRobot sells a similar product for NO2, H2S, and several other gases).
a. What is the name of that 5-prong socket that the sensor uses to connect to that board?
b. Is there anything special or custom about the board compared to the sensor? Superficially, the board looks exactly the same for all of the NDIR gas sensors that DFRobot sells.
c. Is it possible to purchase just the board, and not the sensor?
- Looking at GasLab’s NDIR CH4 sensor
a. Is this socket sufficiently standard that if I could obtain just the board from the sensor in (1) I could stuff this CH4 sensor into it and move forward?
Hello @anteater and welcome to the RobotShop community!

Not DFRobot but perhaps this one could work for you:
a. What is the name of that 5-prong socket that the sensor uses to connect to that board?
Unfortunately, we don’t have this information, if you’d like you can ask the manufacturer directly at:

b. Is there anything special or custom about the board compared to the sensor? Superficially, the board looks exactly the same for all of the NDIR gas sensors that DFRobot sells.
It is the same board used for the O2, CO, H2S, CL2, NH3, SO2, NO2, O3, H2, HCL, and PH3 sensors.
c. Is it possible to purchase just the board, and not the sensor?
No, it isn’t possible.
Looking at GasLab’s NDIR CH4 sensor
a. Is this socket sufficiently standard…
Again, it would be best if you ask the manufacturer directly.

Unfortunately, the sensor you suggested starts at minimum of 200ppm, and is not suitable. I need to be able to sense at the scale of single ppm.
