Ultra-Low-Power CO2 Sensors Enable Wireless Remote ...

2020-04-01· The module consists of four major functions, a mid-IR LED, a photodiode, an optical light path and a microcontroller. Light from the LED is injected into the optical cavity, which contains the CO2 gas that has been allowed to enter it through a hole on the top surface. The light that passes through the optical cavity is detected by the photodiode. The signal from the photodiode is digitised by ...

2021-05-21· The CO2 reading can be viewed from the app and via the indoor module led bar. You can touch the top of the indoor module and the led bar will light up, showing the current status of the CO2 level. The CO2 sensor is accurate at reading CO2 level and, it will re-calibrate itself every time the CO2 level drops below 400ppm. As long as the room is properly ventilated, you won't need to manually ...

Chapter 6: Advanced carbon dioxide (CO2) gas separation ...

In order to use a membrane in a separation process it must be packed in a proper device, a so-called membrane module. A conceptual scheme of a membrane module is shown in Fig. The requirements that a membrane module must meet are low production costs, high packing density, low energy consumption, and good control of concentration polarisation.
