Now you can quickly integrate the Sensirion SEN6x environmental sensor node into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding - thanks to this here Adafruit SEN6x Adapter Breakout (for SEN66 and friends). We covered the awesome Sensirion SEN66 environmental sensor nodes on EYE ON NPI a while ago; it's an awesome all-in-one air quality sensor, but it has the annoyance that it requires 3V power/logic, and it has a special cable connection.
