What IoT can make against pandemics ?

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.

Monitor a gateway connected to The Things Network

I’ve published a post in January 2019 on a solution to alarm you TTN gateway. It was based on noc API but these API have been deprecated. It means this solution is not working anymore.

So I’m investigating some new solution: the more relevant is the use of TTN cli solution.

Let’s seen what can we do with this.

The other Sigfox Connect news

During Sigfox Connect 2019 we had different announcement like ultra-low power devices and ultra-low-cost IoT devices with a BOM under a single $. There are the main announcement in my point of view but we have also had much more coming with updates on previously seen technologies.

At first Sigfox announced the ability to deploy a private network, we are going to see what it could means as the details have not yet been given. Next I’ve got update on satellites connectivity and bubble service announced last year.

All about the Sigfox Connect button

As a gift to the participants of 2019 Connect forum, Sigfox has offered a connected button. This button is the first official device based on the ultra-low cost technology detailed in my previous post about $1 Iot. This device is based on a single SoC, a CMT2189C chip from CMOSTEK. This chip usually made for garage door remote controller is offering a low-cost solution ($0,25) with a MCU+Radio solution, compatible with Sigfox.

In this post I’ll detail what are the components of this solution and the real price you can achieve for a such device to verify the low cost promise.

Sigfox published the reference design for this type of IoT devices, including the button elements. Where writing this post, I did not add a chance yet to read the final version of the document and the estimate is based on reverse engineering of a prototype I’ve got a month ago. The reference design can be obtained from build.sigfox.com.
