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.
@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.
