The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

As you’d expect, you’ll need a couple of Raspberry Pis, a touch screen, a temperature sensor, a Raspberry Pi camera, and a pair of Wi-Fi dongles.

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.
