Interesting. Some pictures of the microturbine would be good. Just how big (or should it be small?) is a microturbine?

RE: Micro Monster - Succulent Plants Monitoring System (part-6) Final Testing and Demo

Aawesome.

Can you add small clear tube and water pump. When it signals dry... pump will water plant. Give it 3-5 seconds depending on how much pumps out at a given time.

then send a notice to cell phone msg of plant A dry, plant A watered.

also, can I set up to 6 potted plants with a single raspberry pi?

plz email me at altonddavisjr@yahoo.com so I can receive info quickest.

thx boss!

Nice reuse on your datalogger project. Being able to build on an earlier project for a new purpose is the sign of a good engineer.

Great project. Let us know if it works and whether the data was useful.

A good project. Did it measure the data as required?

RE: Plant a seed and watch it grow... (Part 3: presenting a new unfuzzy creation, well almost)

I just had to put this one to bed... Here is my environmental sensor unit set up. It is now a standalone unit and uses the BLE Environmental Sensing Service with some added customised characteristics.

When I started out on the "feature creep" part, I was scratching my head as to which would be the simplest BLE module to use with my Arduino UNO, when the solution was sitting right under my nose in a box, looking all forlorn. It was the now defunct Arduino 101. And boy oh boy, it worked a treat and so much simpler than say trying to use the ESP32 BLE Arduino libraries, which don't use the correct terminology and are way too over complicated, memory/resource hungry and crash far too frequently (all classic signs, in my opinion, that the competent code writers did not fully grasp the BLE spec).

[View:https://www.youtube.com/watch?v=C_VlHhhs6Go:740:466]

The fun part of the project, was including a characteristic for a small USB (5V) fan. I have options for the remote turning on and off of the fan and for auto mode, which triggers every time the sensors are sampled (the idea is to raise a bit of dust with the fan on in order to measure dust particulate concentration).

The code for the project is as follows:

This has been a very interesting project and I have enjoyed reading your blogs. I have a small cactus plant, which is many years old now, probably 10 or more, it is now maybe10 cm high, double it's original size, it was a gift to my daughter - who strangely - did not take it with her when she left home. Still, I like it because it doesn't seem to die. It just sits in the window getting hot and cold. Sometimes I water it, mostly I forget. I changed its plant pot to one slightly smaller a few years ago, which it seemed to like. I think a data logger like yours wold just show my neglect.

One day I hope it will flower - assuming it does actually flower.

RE: Plant a seed and watch it grow... (Part 2: grafting in a new branch called mDash)

genebren — Wed, 14 Aug 2019 16:20:39 GMT

BigG,

mDash looks pretty cool. I really like the OTA as well as the RPC features that this software provides. This is something that I am going to have to keep in mind for future projects.

I worked on a large ZigBee project for an automated lighting systems, where we would have 100's of nodes active in the building. The OTA function was extremely slow as ZigBee traffic has a lot of overhead as it 'echoes' messages throughout the mesh. I rewrote a layer of our OTA process, where we could send incremental update files (diffs) so we could stitch together the new FLASH image, based on the existing files and the 'OTA' changes. This allowed us to be able to update the mesh with new firmware in a couple minutes, versus the several hours that it use to take.

Thanks for the great info!

RE: LoRa Experimental Environmental Sensors (LoRaXes) - Conclusion

TPL5110 based power control application will be great.

BME280 will also be a great choice. 3in1 digital sensor with pretty low power consumption.

Transmission range will be pretty short (p2p not sure about connection with a gateway) if it is placed inside a building. it can be increased by reducing the rate rate but not that much.

I will love to see the results if you manage to get a pretty decent range with this board.

The best GPS accuracy I have every seen is of SONY SPRESENSE board (~2m).

HI Ralph,

This has been a great series with nice write-up and descriptions. I will be very interested in how you get on with the TPL5100.

Dubbie,

Moving in the right direction. It seems that you could sample the background (no pixels registering a higher that normal value) and calibrate the device so that it would give a more accurate score when an object is present. Also, seeing movement (the blob changes position) could be used to also improve the detection score.

Good luck wrapping this up!
