Contact less connected thermometer

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.

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.

HTMicron iMPC the STM32-S2LP Sigfox SIP

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.

UnaMKR Mini breakout board

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.
