Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Aside from the Uno and the ultrasonic sensor, you also need a PHPoC Shield to connect the board to the internet and a power supply to power up your Arduino.

You can even build yourself something simple based on an Arduino Uno! The build uses Panasonic’s cheap “Grid-EYE” infrared array as the thermal sensor, in this case, a model with an 8×8 ...
