Arduino Uno has 6 0n-board ADC channelswhich can be used to read analog signal in the range 0-5V. It has 10-bit ADC means it will give digital value in therange of 0 – 1023 (2^10).This is called as a resolution which indicates the number of discrete values it can produce over ...
电压转换方式: Vin为输入(被测量)电压;Vref 是参考电压,若不设置就是供电电压,Arduino UNO为 5V;resolution 是模拟端口的 ADC bit,Uno 模拟端口为10bit,Result 为 模拟端口的测量结果,数值为0~1023。程序如下: /* 作者:Ardui.Co 效果:LM35 简单温度测量 版本:1.0 更新时间:2017年1月9日 */ int LM35 = A...

To understand, ADC resolution let’s take an example of ADC with a 2-bit resolution and a reference voltage of 4 volts, it can only represent the voltage with four possible resulting values that are 2^2. The input voltage and digital output will be according to this table: As you can ...
分辨率和精度—即Resolution和Accuracy。这是两个不同的参数,却经常被混用。并且ADC制造商在数据手册中定义ADC性能的方式也令人困惑,可能会让大家在应用开发中导致错误的推断。但事实上,分辨率并不能代表精度,反之亦然。 2022-05-12 15:19:58 ADC的各种指标如何理解,如何提高ADC转换精度 ...
