FOR MH-Z14A NDIR CO2 Module 5000PPM PWM NDIR Serial Port Single Channel US

hi I'm going to be talking to you about the carbon dioxide since MHz a 1/4 or more specifically the demand for a which in my case has a little white connector ribbon cable connector here on the left should also point out that my sensor is a 5000 ppm not the usual 2000 ppm we can start by showing a part of the data sheets here we can see that your working voltage for the sensor is at roughly 5 volts so it's quite suitable fully the Raspberry Pi even with the the output signal 0.4 to 2 volts or with zero communication at you I think it's around about three and a half volts so it's very good for the Raspberry Pi and unusually when I bought this sensor and I had to look around now there doesn't seem to be any any programming solutions for the Raspberry Pi other than a Python script which I saw so that's us yeah the idea of this screencast is to show my two different programs one being a PWM
