I am new to the particle ecosystem (I’ve really only used arduino before this).
I’m trying to hook up a Gravity Analog TDS sensor to a Particle Boron and I’m having trouble importing the library for it. It doesn’t seem to be in the Particle Libraries list, so I tried downloading the library from GitHub and putting the file in the src folder in the Particle workbench IDE.
[Here’s](https://github.com/DFRobot/GravityTDS/blob/master/GravityTDS.h) the link to the GitHub library.

You’ll need to rearrange some files and create some folders within the `lib` directory in your Workbench project. It’s described [here](https://docs.particle.io/firmware/best-practices/libraries/#using-non-libraries).
You’ll probably also need to comment out `#include ` which is needed for Arduino but does not work on Particle.

You will also need to change the `aref` voltage value from 5.0 (volts) to 3.3 using this library function:
```auto
void setAref(float value); //reference voltage on ADC, default 5.0V on Arduino UNO
```

Thanks for the reply. Would you be able to explain why? I hello world-ed the sensor with an uno and used 5V.

@hparris3980, the ATMega328 used in the Uno is a 5v processor whereas the nrf52840 used in the Boron is a 3.3v part. So, you will need to power the sensor using 3.3v (for which it is rated) and define the reference voltage for the analog-to-digital (A/D) converter as 3.3v. This value is used to convert the A/D digital value into an equivalent voltage in the library.

Thanks so much!
