2019-12-03· The sensor outputs the measured CO2 level in a PWM signal and a UART (serial) stream. We will use the UART interface in our example. Connection . We need four connections: power (5V – 150mA, GND, Rx and Tx). If you use the sensor with the JST6 cable you can solder plugs on these wires, or use Dupont crimp connectors. In the case you solder them you can connect Red / Black …

Page 2 CO2 Sensor UART Communications Protocol UART Commands from PC to Sensor Commands sent from a host computer or PC to the sensor have the following format:
2016-10-09· The UART readings at least make sense. Normal CO2 concentrations at open spaces should be around 400ppm, and a room may well be around 650ppm. While calculating ppm2, since you defined tl=1004-th I think that (th+tl-4) will always be 1000, so you can use ppm2=2 (th-2) I'm quite sure that there are two versions of this sensor.
2017-08-14· I have a CO2 sensor (SenseAir S8) that is onboard a CO2 measuring device (called upHere co2 meter). The device is only showing 0 as the CO2 level so I'd like to try and troubleshoot. The S8 sensor supports UART communication. The protocol is a variant of MODBUS and is well documented. I made several attempts at using the AD2 to communicate with ...
DFRobot released its latest wide range Arduino infrared CO2 sensor, which effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication mode.

2017-07-11· UART serial interface and Pulse Width Modulation (PWM) output. A nondispersive infrared sensor (or NDIR sensor) is a relatively simple spectroscopic sensor often used as a gas detector. It is nondispersive in the sense of optical dispersion since the infrared energy is allowed to pass through the atmospheric sampling chamber without deformation. Principle of operation: The main components of ...
