Hey congrats. Very nice.
I’ve been playing with the Particle.io photon as well, nice environment and easy to use.
I was wondering how do you plan on calibrating it and tracking the accuracy of the readings? – perhaps too early to ask that.
I always add a low cost aluminium measuring rule or USGS style manual gauge.
I’ve been using thingspeak.com for recording – here is a basic visualization of data from a simple rain gauge I measured – actually using another board – but the Particle photon is so much nicer and I will be using it
The nice thing about thingspeak is its basic data visualization, and you can decide what data to share on a public URL, and also what to keep private for management behind the scenes.
