I am fond of cooking and trying different recipes to expand my knowledge about foods. And, as an electronics enthusiast, I enjoy tinkering with gadgets to get more precise measurements while cooking. In that way, I ensure delicious and consistent outcomes with little effort. To measure the internal temperature of foods (roasts, steaks, etc.), I utilize a meat thermometer while cooking. Although meat thermometers can easily monitor the internal temperature to avoid overcooking and serving dried-out food, they lack the ability to measure the surface temperature. Thus, I decided to develop a wireless infrared kitchen thermometer from scratch.

An infrared kitchen thermometer can be employed to verify:
Ā
food and beverage temperatures,
Ā
the oven temperature,
Ā
refrigerator and freezer temperatures,
Ā
boiling and cooled milk temperatures while making yogurt,
Ā
hot oil temperature while deep frying.

I decided to use the Tuya IoT Platform in this project because it allowed me to develop a mobile application interface compatible with various operating systems (Android and iOS). In the following steps, I will explain how I benefited from the Tuya IoT Platform to improve this project in detail.
Ā
To get accurate temperature measurements, I utilized a DFRobot TS01 IR temperature sensor. This sensor can measure the surface temperature from -70°C to 380°C while providing a maximum accuracy of 0.5°C.
Ā
Finally, I added a 5mm common anode RGB LED to show the connection status between the infrared thermometer and the Tuya Cloud.
Ā
On the thermometer's mobile application interface supported by the Tuya Cloud, the user can monitor two different data points regarding the surface temperature:
Ā
Cook_Temperature - Unit: °C
Ā
Cook_Temperature_F - Unit: °F
