BIG diy SENSOR topic


#124

I made bad experience with such a moisture sensor from Tindie.
The weak points of these are, that the SMALL side of the board is not sealed and it gets whet under the lackage and it blisters off (in my case after some month!)
Very sad, that the seller take no notice of the problem, nor action to replace it.
So you have to seal it with “tropenlack” to make shure it’s prepared for a long life.

good results with this kind of sensor right now

Those small soil sensors are pretty poor and only an indication that the soil is wet or dry and wont last very long. To do any serious long term soil moisture monitoring at any depth then you’d need to look at professional sensors from Irrometer, Sentek and others.
They may not be budget sensors, but you get what you pay for,

Hello

At this moment i found this :
PiGI goes TTN - IoT Radiation Monitoring

At this point, 12 PiGI - Raspberry Pi Geiger-Müller Interface nodes are in active deployment at TDRM, helping to monitor the environment independently and so far reliably. Additional 12 nodes are on the current roadmap. That is a great success story and just in the spirit of the idea, development and open-source model of it.

Now the TDRM Working Group at Karel-de-Grote Hogeschool, Campus Hoboken in Antwerp pushed it even further and developed a LoRaWan based TTN (The Things Network) Adapter for the PiGI, to have it connected to the Internet of Things.

The website of the particle sensors vendor Plantower (known for example for the PMS A003 DUST SENSOR PM2.5 product) is out of service; the web hosting expired.

Has the company been terminated, or do they have (hopefully) a website at another web address?

See for yourself at

Hopefully not as just took delivery of a couple of sensors last week! :frowning: (Via an ebay vendor) Looking for more over coming months… eek!

Don’t panic. I was exchanging emails with them earlier this week. It looks like they have a hosting problem.

The Plantower website is back online :slight_smile:

Good to know thanks!

So…

PMS5003 or SDS011?

I am reading everything and the opposite about these two…

Did anyone make an RFID reader?
