The DS18B20 digital temperature sensor provides 9-bit to 12-bit celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that by definition requires only one data line(and...
它可能看起来令人生畏,但在进一步学习本教程之前,您应该熟悉DS18B20单线温度传感器的基础知识。 将多个DS18B20传感器连接到Arduino 连接非常简单。 首先将所有DS18B20并联连接,即将所有VDD引脚,GND引脚和信号引脚共用。然后将VDD连接至Arduino上的5V输出,将GND连接至Arduino接地,并将信号引脚连接至arduino上的数字引脚2。
Note that pin 1 (GND) is the leftmost pin when the flat side of the sensor (with the text printed on it) is facing towards you. DS18B20 digital temperature sensor connections A waterproof DS18B20 sensor gets connected in the same way. However, the color of the wires can be different depe...
