Story

Why this project?

Puppies are animals that are not afraid of heat or cold. In order to care for the puppies who stay at home alone during the working day, I thought of doing a test for the puppies to detect the temperature changes at home, so as to get a reference to improve the environment later.

Project Introduction

Through the temperature and humidity sensor, the device monitors the puppy's ambient temperature. When the temperature is higher than 26 degrees Celsius, it will display "hot dog", indicating that the puppy feels hot, and it will display "good" when the temperature is lower than 26 degrees Celsius, indicating a comfortable temperature.

Process and steps
