What is it?

This is a Winsen MH-Z19B CO2 sensor with a micro-usb interface to allow simple cable connection to any USB port. The unused (PWM and analog) connections are in heat-shrink tubing. Measurement range is 0-5000ppm, with a custom serialized Micro-USB board.

Why did you make it?

To have a way to monitor air quality at and around my home. Indoor CO2 concentrations are the subject of a couple of recent studies:

Fossil fuel combustion is driving indoor CO2toward levels harmful to human cognition

Hazards of Global CO2 levels

I make sensor assemblies to use with Mycodo This sensor design allows optimal placement when used with long USB cables.

What makes it special?

The USB interface helps overcome the serial port limitations of the raspberry pi and allows longer cables without errors in data transmission.
