In the first code example, I will show you how to take temperature readings from a single sensor and display the result in the Serial Monitor. The subsequent examples explain how to read multiple sensors with a

现在我们只剩下I2C通信的引脚。在Arduino UNO R3开发板上，SDA和 SCL位于靠近 AREF 引脚的排针上。
The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value and compares it with the set threshold. The results are: when the measured room temperature is less than the minimum of the threshold value; then, the microcontroller turns on the heater. If...
