Just an FYI I’ve just picked up that some of my sensor have lost data on or about Aug 6 1pm PST for 5 horus.

I’ve made great efforts to track the delivery of measurements, I’m thinking its MMW that has swallowed the data.

Hey thanks for the reference. I’ve also been monitoring blynk .

Do you offload the data regularly? – that seems to be the big gotcha is figuring out how often to download data.

This is rather a good summary of over-the-air updates – https://blog.arduino.cc/2024/06/13/why-do-ota-updates-matter-in-iot

I wonder if anybody is trying the arduino cloud that it uses.? https://cloud.arduino.cc/

Its some good thinking and takes time to scope it. From what I understand, some of the AI on vision detection may have a lot of promotion without understanding what it takes technically to make it reliable. I’ve […]

For the aspect of visual analysis – perhaps one of these hardware modules might be appropriate Which partly means choosing the size of a camera, seems like its is 2Mpixel or 5Mpixel There is also a discussion […]

Hi @braedon-dority, my take is that the first step is to have personal documentation to be able to repeat your work, and that you can read it. Just to be basic, part of the learning is how to do documentation that you can then read your self.

Personally I find I come back to a working sensor some years later – and then want a traceable reference…[Read more]

Hi @Mike Miller, good to have a variety of skills, and the target of making stuff/engineering is to have a customer or user -your 🙂 and then the user phrasing requirements – often iteratively with the engineering […]

Thanks so much for the posting. Fascinating. While R.Pi might be great for prototyping – it does require a lot of mW power, and it can’t be put to sleep. A great way of reducing total deployment costs is to have […]

Thanks for the update, its nice to get the visibility on what is coming. Of course the real world is its also useful to know when something change, and then adapt to it ….. or sometimes its a case of figuring […]
neilh20 replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 6 months, 3 weeks ago

Congrats – nice to see.

I guess the fundamental problem of power management is still there and can bite any time the power drops – and then likely will require a site visit to get the site restarted. Getting enough power is a band aid to enable reporting readings. So long as the power supplied exceeds the power used by a good margin it works. :)…[Read more]

@jamesp thanks for sharing. Interesting where the “banana skins” are to slip on.

Nice to know its got low quiescent current – end of last year I also got the same SanDisk Industrial MLC MicroSD SDHC UHS-I Class 10 SDSDQAF3-008G-I withs its specified Operating Temp Range: -25°C to 85°C , but haven’t measured its current 🙂

A follow up – I had this running for about 6 weeks last year.

The code is in my fork is at https://github.com/neilh10/ModularSensors/tree/release1/examples/samd_log_display_mmw and is available to the main at any time.

For test purposes, I positioned the temperature sensors in my office, attached to different areas round the heating vent, w…[Read more]

I’m very much a fan of ModularSensors and the discussion board as a place to be real with technical issues. I do so appreciate the unique place EnviroDIY has been curated to be, to try some remote wireless terrestrial monitoring. Its the nitty gritty of environmental monitoring and the engineering it takes. Its tough to find out what these ser…[Read more]

I haven’t had much luck getting to 0.5mA with mega1284, it was with the Mayfly 0.5b- https://www.envirodiy.org/topic/testing-power-consumption/#post-15252 My notes on measurements is that it was between 2-2.5mA. I did get well beneath 0.5mA on another project with mega2560, but that was a lot of hardwork, and also ended up with a higher valu…[Read more]

@jp – the charger relationship doesn’t quite work that way. The 5V 2.0A is typically the stated maximum the charger can supply – however for the battery charger circuit there are limitations. I use a USB Meter to determine what is actually going on.

The Mayfly 1.x charger circuit is to 0.5A as default but can be changed to 1.0A. I always change…[Read more]

Matt Thanks for posting. I’m away from my computer till next week, so I’ll be interested to look when I get back.
Seems like SpokaneRiver-Peaceful has good solar, and the battery never gets low.

@oakleynode wow interesting you are looking at RSSI and it has a lot of variation. I haven’t characterized the RSSI result for a high percentage of failing calls.

Another system that is also on the edge, and I added a new antenna that improved it, the reading is -81dBm https://monitormywatershed.org/sites/TUCA_Mi06/

I’m seeing a gap in data downloaded from the MMW database – about 5 days worth of lost readings.

It seems to be across all my devices. I spot checked a couple of other devices, and they also seem to be missing.

I noted it here but it hasn’t got a response https://github.com/ODM2/ODM2DataSharingPortal/issues/685

The lost data initially came up…[Read more]
