May 06, 2021· Co2 concentration drops below 400 ppm - MH-z16 Co2 sensor. I am not using any additional boards for this. I simply cut the wires and connected it directly to arduino using UART interface…. Apparently there’s a I2C/UART interface board but I do not have this. The only issue with this is that the cocentration of co2 keeps dropping below 400 ...
Description. The MH-Z19C module is a next-generation CO2 sensor based on the non-dispersive infrared (NDIR) principle. MH-Z19C is the successor of the widely popular below for a comparison. The MH-Z19C 400~2000ppm CO2 sensor has built-in temperature compensation and communicates over UART and PWM with the host controller.
The MH-Z19 sensor is manufactured by Winsen Lt., China and the measurement method used is based on the non-dispersive infrared principle to detect the existence of CO 2 in the air.. Key features according to the manufacturer are: * good sensitivity * non-oxygen dependent * long life * built-in temperature compensation * UART serial interface and Pulse Width Modulation (PWM) output
Feb 16, 2018· In order to verify that our choice was a valid one, we then had to correlate the readings we carried out as regards the MH-14Z NDIR (Non Dispersive Infrared Sensor) sensor, having a +-5ppm resolution in the 0÷2000ppm CO 2 range; you will find an excerpt in figure. The reference sensor is an infrared operating one.
