MMD1013S VOC sensor module library

Other Hardware Sensors

A new inexpensive gas sensor module has appeared on the market.
It is based on SMD1013S from IDM Technology, Inc, runs on 5v, comunicates with I2C or UART
It is a very basic sensor, but it can complement other popular sensors like the CCS811, because the sensitivty is different to different volatiles.
Looking at the datasheet, I see that reading the sensor consists of just sending the I2C address and reading two bytes.
B1=3Bh (address for I2C, for UART it would be 2Ch)
B2=TVOChigh
B3=TVOCLow
Calculating the total VOC concentration:
TVOCValue = (B2*256+B3)*0.01

The pdf can be found at http://www.idmsensor.com/cp/html/?108.html. It is in chinese, so I translated the file online, but I'm unable to upload it here.

I'm hoping someone could make a simple library or bit of code for using this and make it publicly available, allowing newbies like me to use this module.

An Arduino expert here could make this library in a few minutes, I'm sure! Having it here would be great for any newbie wanting to give this sensor a go.

Can we guess that you have gotten it to work? Can you give some examples of how you are using it?

I still haven't got it working. When I finish sorting out other issues, I will eventually give it a go.
