SenseCAP (Seeedstudio) has launched a Kickstarter campaign for launching it new LoRaWan product, a tracker based on LR1110 Semtech transceiver. This Kickstarter is a bit unusual as the product is already designed and operational. It’s more a way to have a minimum of order to initiate a production batch with a guaranteed volume.
This tracker exists in different version with different capabilities and sensors. The version I received for testing it is a T1000-A, able to get outdoor position with GNSS, indoor position with WiFi, temperature, light and accelerometer data.
Two years since I did not published my IoT slide deck. Here is the new version, now about 345 slides about IoT topics including Sigfox, LoRaWan, Helium and much more. In this edition, you will also find some slide about the digital transformation impact on the society and the environmental impact.
All the slides on this deck can be freely reused for any educational content; Most of them are also used in my different MooC you can fin on my Youtube IoT Channel
With the Solana migration, the Helium ETL has became obsolete, the Proof of Coverage (PoC) data are not anymore on the chain but they can be publicly accessed from an AWS bucket. We are going to see how to access these data and what I’m developing to manage them.
The new baby in Kerlink family has arrived, it’s iZeptoCell ! Ok, I’m a bit late to write this blog post and it came alive a couple of months ago. When I say baby, I really mean baby, no due to its age but more related to its size !
This LoRaWan gateway is really small and can take place in any indoor environment looking like a sensor but providing a wide range connectivity for many devices deploy around. This is a really good option to cover a small / medium company floor up to a building.
This gateway exists with an Ethernet connectivity like the one I’m testing and with a Cellular connectivity, something appreciated when corporate IT dislike having devices on the corporate network.
Bad news yesterday after a power failure on a server, impossible to restart my Helium ETL service: the database has been corrupted and the service is failing with the message “invalid page in block 54206178 of relation base/16384/186119818”
I had to spend time on the web and chatGPT wasn’t helping me (I’m kidding, this bot is stupid) to find a correct way to solve this, luckily, this has been resolved and here is the way I did it.
In this tutorial, we will see how to make an image clustering based AI with the Seeed Wio Terminal and the Grove AI camera. There are different tutorial on this, the main source of this tutorial is located here. The purpose of this is to have a step by-step approach for my student to realize this in a limited time they have.
This is based on SeeedStudio K1100 development kit.
