    Description

    Experience Level: Entry
    General information for the business: We create iot based sensor systems
    Description of requirements/functionality: Hello friends, I have a Nodemcu ESP-12E Wifi module and a MQ138 Formaldehyde gas sensor in order to measure the formaldehyde level in environment in ppm. I want two things:
    1. Arduino library for MQ138 Formaldehyde sensor to add in Arduino IDE
    2. C++ code to use in Arduino IDE in order to communicate between nodemcu and mq138 and calibrate and calculate the ppm value of formaldehyde in output (then i want use the result to send to an IoT platform, but don't need headers and etc for this purpose).

    please take a look at these helpful sample material files. Already i had created a MQ135 co2 gas sensor system using nodemcu esp-12e and mq135 , but now in this new project i want to use MQ138 sensor to measure formaldehyde. The things that i want is like as this: MQ138 library to add in arduino library something like the folder that is in zip file . Then i want a c++ code with an include header like "include MQ138.h" and in continue containing calibration and calculation of formaldehyde by ppm (similar to .txt file that i included but note that its for MQ135 sensor that calculates co2 and in that project i used Cayenne platform to see results).
    OS requirements: Windows
    Extra notes:
