Display Temperature from MAX6675 Using ESP32 over Bluetooth on a Mobile Phone
In this tutorial, we learn how to use a MAX6675 thermocouple sensor with an ESP32 to measure temperature and read it using Bluetooth on a mobile phone or tablet device.
If you need to use a MAX6675 thermocouple sensor with an ESP32 (no Bluetooth), see this page.
If you need to use two or more MAX6675 thermocouple sensors with an ESP32 (no Bluetooth), see this page.
