Peter, Yes, that's my current favorite turn-key environmental sensor as well. Sure, you can home-brew a slightly cheaper solution. And the Arduino world is full of random sensor examples, which you are free to deploy and debug. But the Sparkfun unit just works; out of the box. From the first second after power-up, and once every second after that, it does the one thing it is designed for: sense and report.
Their model is serial (USB) ascii output once a second. This works: without API, without command / response, without tie-in to a particular operating system, or driver, or downloads, or app, or API, or language du jour, or login, or encryption, or cloud. It's how digital sensors should be designed. KISS. This is also why so many of us like the hp 53131A / 53132A talk-only mode. It just measures and reports. The picPET and TAPR TICC were designed the same way. /tvb ----- Original Message ----- From: "Peter Vince" <petervince1...@gmail.com> To: "Discussion of precise time and frequency measurement" <time-nuts@febo.com> Sent: Thursday, April 05, 2018 6:24 AM Subject: Re: [time-nuts] Environmental sensor recommendations > Hi Mark, > > SparkFun have some boards that have multiple sensors.
