Contactless Temperature Monitor with Wio Terminal

How to check the temperature with no contact? The project combines PIR detection, IR camera and hand-gesture recognition for perfect safety.

The project is built around the Wio Terminal with three Grove sensors. The Wio Terminal brings a screen and WiFi for the IoT extension.

Release 1.0.6 of the project improves the local display.

By default, the image displayed has the same resolution as the thermal sensor, or 8x8 resolution.

​The initial image is resampled through a bi-cubic interpolation to provide a nicer picture, here in 16x16 resolution.

The FPU of the ATSAMD51 manages all the computations required by the interpolation effortlessly.

That’s looks a huge improvement, :clap:t2: :clap:t2:

@salman Look at other people’s demos. But the your MQTT demo is still there, do you have any update?

Yes, @Baozhu, I’m working on it, I’ll update you.

I wanted to use the new set of IoT libraries with Seeed_Arduino_rpcBLE, Seeed_Arduino_rpcWiFi , Seeed_Arduino_rpcUnified and Seeed_Arduino_FreeRTOS, but compilation fails.

I’ve created the corresponding ticket at Using new rpcWiFi library instead of old AtWiFi library throws error #1.

The reported issue was quickly fixed with fd32c56.

Release 1.0.7 adds support for the new Seeed_Arduino_rpcWiFi library.

In line 68 of the main ContactLessTemperatureProject.ino, just replace

#include "AtWiFi.h"


#include "rpcWiFi.h"

for the new library.
