· The advantage is that you keep logging and uploading firmware over the serial (USB) port. When connecting the serial MH-Z19B sensor to the ESP8266 board, you have two choices: Recommended: use software serial port (any pins, 12 and 13), lower baud rate, and keep logging. Use hardware UART (pins RX and TX) and disable logging, see also this ...

Can CO2 Kill Insects and Garden Pests? |

Scientists at UC-Davis describe the CO2 levels and times required to kill various insects. Clearly, some pests are much less tolerant of high levels of CO2 than others. In addition, indoor growers have reported in blogs and online user groups that high concentrations for short periods of time several days apart can achieve the same killing effect.

7 Reasons Why You Should Measure CO2 Inside Buildings ...

· Indoor CO2 is measured with a relatively inexpensive technology called NDIR, or Non-Dispersive Infra-Red technology. Figure 3 is a diagram of a simplified NDIR based CO2 sensor. At one end is a LED source emitting infra-red light and at the other end is a detector with a specific light filter to detect only CO2. Gas diffuses into a chamber between the LED source and detector. The amount of CO2 ...
