How to work with the C02 Sensor MH-Z19B

[bitttttten]

Hi all,

I have a MH-Z19B that I would like to get talking to my Pi B+, although the pins on the GPIO needed for it are already taken up by a RaspBee module.

Are there any other options? Could a JST to USB work?

Welcome to the MySensors forum. MySensors is a library you can use to create a wireless mesh network of sensors which communicate with a central point, such as your Raspberry Pi.

You could attach an Arduino Nano to USB and talk to it via Serial.

You could create a MySensors network, which you could also communicate to via an arduino+radio on your USB port. Then you could attach countless sensors. There is a ready-to-go sketch for the MH-Z19B.
