· MH-Z19 python datalogger test program. The simple test program opens the UART com port serial0 and tries to read CO 2 measurement values from the CO 2 sensor every minute. The program prints every measurement to the screen and logs timestamped measurements to a csv formatted file, which is given the current date and time as the filename.

· I tried to read the temperature and status, but it looks the MH-Z19B is not the same as MH-Z19 and returns always status zero and temperature looks maybe 10 degrees higher (so no value minus 40, but maybe value minus 50).
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
· Erster Teil der Serie um einen MH-Z19 Sensor zur CO2 Messung zu verwenden. Er ist relativ günstig, und kann leicht mit dem Arduino ausgelesen werden.
· The MH-Z19 features a UART serial interface and 5V power supply and IO levels. This makes is easy to connect it directly to a Raspberry Pi or to a PC (If PC, you need to use an USB/serial converter(CMOS/TTL levels, not RS232 levels)). It also features an pulse width modulated (PWM) output where the duty cycle changes with CO

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 …
· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …
MH-Z19, sometimes also denoted as MH-Z19A: original version, with a less optimal auto-calibration function; MH-Z19B: improved version which you want; Connecting MH-Z19B The MH-Z19B requires 5V to operate. I've connected the sensor as follows (based on this article and this pinout): MH-Z19B-GND: connect to ground ; MH-Z19B-Vin: connect to 5V; MH-Z19B-Rx: connect to pin 5 / SCL = D1 (for …

· Both sensors are designed to measure the level of carbon dioxide indoors. The CCS811 sensor has many advantages over MH-Z19B - significantly smaller size, lover voltage and current, lower price.. For comparison, both sensors were connected to ESP8266 development boards with very similar firmware. Readings were collected every 10 seconds and sent by MQTT protocol to a Raspberry PI …

The Harbin Z-20 is a medium-lift utility helicopter produced by the Harbin Aircraft Industry Group (HAIG). It was first flown on 23 December 2013 and has a maximum takeoff weight in the range of 10 tonnes (22,000 lb). The Z-20 can operate from locations above 4,000 m (13,000 ft) in altitude as well as from the Liaoning aircraft carrier. It is regarded to be comparable in performance to the US ...
