Fake MH-Z19B (black PCB) (Added by Juerd 04:20, 30 November 2020 (CET)) . There are sensors out there, sold as MH-Z19B, that seem to use the original firmware, but with different hardware.
· Power the flashed device and enter the web server. In the browser by it’s ip. Under the controllers tab enter the details of your Domoticz installation. Go to devices then and add CO2 MH-Z19 sensor as a Device, give it a name and choose the pins you use. Send to controller has a IDX field, here you add the noted IDX from domoticz, which means the data of this sensor would be send to the …
MH-Z19 has automatic calibration procedure. the MH-Z19 executing automatic calibration, its do zero point (stable gas environment (400ppm)) judgement. The automatic calibration cycle is every 24 hours after powered on. If you use this sensor in door, you execute setAutoCalibration (false).

Use the device tab on the ESP Easy webinterface and create a new task by editing one of the available tasks. Select "NDIR CO2 Sensor MH-Z19 [TESTING]" from the dropdown box. Select the GPIO Ports where you connected the RX and TX lines to. Optional settings. Use of formulas. Use of value names
The MH-Z19 sensor is manufactured by Winsen Lt., ... Principle of operation: The main components of an NDIR sensor are an infrared source (lamp), a sample chamber or light tube, a light filter and an infrared detector. The IR light is directed through the sample chamber towards the detector. In parallel there is another chamber with an enclosed reference gas, typically nitrogen. The gas in the ...

· Maybe have a look at the examples in Serial Input Basics - simple reliable ways to receive data. There is also a parse example. You will need to adapt it a little if you want to receive byte values rather than char values.
· how to use. Use as python script. The sudo might be necessary because mh_z19 module use Serial. The differences of the interface between each Raspberry Pi model are resolved inside this module. For example, serial device name is difference between Raspberry Pi 3 and older model, but mh-z19 module automatically detect the model and read from ...
MH-Z19 NDIR CO2 Module 1. Profile MH-Z19 NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature sensor can do temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of …

MH-Z19 CO2 Sensor. The MH-Z19 is a small non-dispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should increase ...
