MHZ19 CO2 sensor (see this followup post) Other pins can be used to control other devices. For example, the weather station can open a window and turn on a ventilator when CO2 level is high, or it can turn on an AC when it’s getting too hot. UPDATE: It turned out that mpfshell may not work well on Windows. ampy may be a better option ...
The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19 C is the successor of the widely popular MHZ19 B. See below for a comparison. The MHZ19C 400~2000ppm CO2 sensor has builtin temperature compensation and communicates over UART and PWM with the host controller.

20170323· * MHZ19 CO2 sensor * It communicates with your board over serial at 9600 speed. SoftwareSerial mySerial(10, 11); // RX, TX . You can choose other pins if you prefer. Missed that one, got confused due to the multiple possible ways to connect this sensor. (UART, PWM, etc) So TX, RX, GND and Vin sould be enough?
