For this project, we wanted an I2C sensor that was at least capable of measuring the temperature, so we simply started by searchingi2c temperature sensoron Amazon. After a bit of research, we found that theBME280 sensorfrom Bosch was available on several inexpensive break-out boards, and it...
We will take the Grove - Sound Sensor as an example to introduce you how to use this board. Hardware connection Step 1. Plug the 8-Channel 12-Bit ADC for Raspberry Pi (STM32F030) into Raspberry Pi. Step 2. Connect the Grove - Sound Sensor to A0 port of the ADC module. Step 3. ...
大部分传感器的输出都是与电压成比例关系的,电压值一般采用ADC来测量,而ADC一般有固定的位数,如8位ADC、12位ADC等,ADC的位数会影响测量的分辨率及量程。例如图 448,假设用一个2位的ADC来测量长度,2位的ADC最多只能表示0、1、2、3这四个数,假如它的分辨率为20厘米,那么它最大的测量长度为60厘米,假如它的...
