In a previous post I’ve been presented an idea for creating a kind of satellite solution for watching over pandemic progress over the world using low cost connected thermometers. You can get the details of this idea in my blog post “What IoT can propose against Pandemic“. Basically the proposal is to add an ultra low cost IoT communication feature into a thermometer and report the information when an over heat has been detected. That way we could be able to determine the level of pandemic and its geographical progression over time. So I won’t detail all the business model and financing proposal, you will find all of this in my previous post.
The second step is now to make a prototype of a such device to show how too make it possible. For making this I’ve selected the thermometer you see on the picture above and decided to hack it and connect it to Sigfox network. This thermometer comes from Amazon and cost 14€ but is really like all low cost thermometer we can find.
Ten month ago, I was starting investigating the Ultra Low Cost Iot thanks to Sigfox given access to the experimentation they made in this area. The Ultra Low Cost IoT is defined by manufactured devices under or near the cost of $1.
Such level of price are enabling scalable deployment of devices and mass data capture, more than it has ever been able to made. And basically, it is not a question of device cost, it is a question of scalable use-cases where the higher device cost where a business model killer.
This is basically reducing the price of devices by a factor of 5x to 10x. No miracle, this is also reducing the device capabilities and concerns different use-cases than the one previously designed. In another word, Low Cost IoT is not classical IoT for a lower price, it’s a new IoT area where we find new use-cases, new business model and more generally is source of innovation.
I’ve recently made a post on how to make a pandemic alarming system based on low cost connected thermometers. This post was more about the organization model and business model than the technological solution and implementation. So I also wanted to continue to investigate the connected thermometer solution, mainly for the fun. As I’ve been sponsored by digitspace.com for some free hardware, it has been the opportunity for testing contact-less thermometers module.
The design I’m going to propose in this post will not apply to the low-cost connected thermometers as the technology I’m going to use is far more expensive to the one I proposed in my previous post.
That said, this design can be useful for companies, public site or free access thermometer booth anyone would like to design at low cost.
For the French audience, I’ve just published a Mooc on Sigfox technology with a practical based on the Arduino MKRFox1200 board. You can watch it for free on Youtube Disk91 Sigfox Mooc. There are 16 short episodes, published every day at 6:15pm french time.

Pandemic prevention and management is an interesting territory for IoT. I’ve seen different projects and solutions made in emergency to help during the Covid-19 crisis like some connected button distributed in hospitals to get assistance for going to toilets. That’s an interesting use case for IoT where you can deploy quickly a solution (20K have been produced in this example) and make it working in an existing environment (an hospital) with no integration complexity with network or other existing infrastructures.
My favorite example is the Us health Weather Map reporting the human temperature sensor information across the USA. I love this use-case because it works on prevention: detecting the rise of the pandemic, show its movement and scale. The current problem is that these data comes from high-end thermometers, using Bluetooth and the number of device is limited. The other problem are the personal information attached to these device.
This is where LPWAN and Sigfox in particular can be used to propose a innovative solution I’m going to detail a bit.

HTMicron is a Brazilian company making System In Package (SIP) solution. During Sigfox Connect, they shown a STM32-SLP product and gave me an eval board for reviewing.
This type of solution is interesting as it is really compact and easy to add in your design: you get a powerful ARM chip from ST + all the electronic needed for a Sigfox global communication system. There is no need for an extra component around the chip, more than an antenna and a power supply.
The price for the SIP is going to be around $5.
Let see how to use that chip.

After presenting the UnaMKR Arduino devkit, Unabiz has made a new version of its maker kit supporting Sigfox Monarch and based on LiteOn module.
The UnaMKR mini is a breakboard solution for the LiteOn module and nothing more. You can easily make your own prototype system based on this board. The price sounds to be $25 to $30.
