Multiple measurement displays at once- co2, temperature, and relative humidity readings are all shown on the lcd display at the same time. Audible co2 sound- the alarm beeps when the co2 level exceeds the preset value. Ndir sensor for co2 detection- non-dispersive infrared technology is used to ensure the reliability and long-term stability.
Introduction. Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared.
· 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 ...

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.

· 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 ...

· Measurements were made using a modified indoor air quality meter equipped with a nondispersive infrared (NDIR) CO 2 sensor. Detected carbon dioxide concentrations ranged from 2150 ± 192 to 2875 ± 323 ppm. The concentrations of carbon dioxide while not wearing a face mask varied from 500–900 ppm. Doing office work and standing still on the treadmill each resulted in carbon dioxide ...

The GasSense NDIR gas sensor, with integrated transmitter, is an innovative measurement module for the detection of CO2, CO, N2O, CH4 or related hydrocarbons. The sensor can be easily integrated as an OEM component into controls, measurement systems and monitoring instruments.
1. CO2 can kill you Outside air has a CO2 concentration around 400ppm and each human breath contains around 30,000ppm. CO2 concentrations greater than 20,000ppm cause panting; above 100,000ppm (10%) CO2 can cause tremors and loss of consciousness; and values above 250,000ppm (25%) can lead to death (Satish et al 2012). CO2 can be hazardous in ...
