Context
I have been using a game camera to photograph a stage gauge around midday to collect water depth data. A secondary us is potential plant phenology analysis. Historically, water depth has ranged from zero to 70 cm or so and the pool has been dry until January or later.

This worked well until the tree to which the camera was attached died.…[Read more]

Hi Cesar,

We (mostly me and @aufdenkampe, I think) have been purchasing them directly from Yosemitech because they are so darn cost-effective without compromising quality. Currently they are subject to the new 25% “Trump Tariff,” but they are still proving to be cost effective. Note that to use these sensors, the Mayfly needs a “wing” to boost…[Read more]

Hi everyone,
I need to adquire the yosemitech sensor to integrate with Mayfly datalogger, i am creating a multiparameter sonde for limnological variables.
Specifically i need the yosemitech Y514-A (cholorophyll sensor)
Does anyone know where to buy them in the USA?
Does anyone know of any other low cost alternative?

Sara Damiano replied to the topic Logging interval resets every ~256 samples in the forum Mayfly Data Logger 1 month ago

Assuming you’re using the modular sensors library, the 2 minute reading on the start-up was a feature that was supposed to help with debugging. The idea was that right after deploying a station you’d want to make sure it was working so you’d want frequent measurements. I took it out in the most recent release because nearly everyone was confused…[Read more]

Sounds like Modular Sensors Library? The original versions had 2 minute readings scheduled at the beginning of logging to make it quick/easy to see if a station was logging upon deployment. I think @srgdamiano recently removed this from the new version of the Modular code.

What sketch are you running? Is it a sample from this forum, or from our Github repo, or something you wrote?

Dan started the topic Logging interval resets every ~256 samples in the forum Mayfly Data Logger 1 month ago

When powering on the MayFly running a script with a Logger object, 10 samples are recorded at 2 minute intervals, regardless of what the value of loggingIntervalMinutes is. After these 10 samples, the logger reverts to loggingIntervalMinutes.

I have additionally found that every ~256 measurements, (in my case, where I’m sampling at 15 minute…[Read more]

colemanjj replied to the topic Water Monitoring in remote locations with a solar Particle Electron in the forum Environmental Sensors 1 month, 2 weeks ago

neilh,
The TDS code currently posted by DFROBOT for the Gravity: Analog TDS Sensor/Meter for Arduino is a total re-write since I downloaded it. The code I downloaded about 6 months ago had an error in it (applied temperature correction to the raw analog voltage) The updated code is much more modular (a bunch of functions) and seems to have the…[Read more]

Nice write up on github thankyou. I’ve got the ParticleIO WiFi going for one project. Particularly interesting your TDS references thanks.

The Spudnik project is designed to monitor water quality and other environmental parameters in remote locations, report over the cell network and post the monitoring data to Ubidots and the Particle console.

The project is described, hardware identified, and the code posted at:

The initial deployment of…[Read more]
