【分享】自制环境参数检测装置接入 oneNet 平台(二)
本帖最后由 xiebinqiang 于 2016-1-27 09:42 编辑第二部分 传感器接入和数据采集 通信的问题解决了,下面在ardiuno板子上接入传感器,采集数据,三个传感器接线方式如下:
噪音传感器 ardiuno
GND-------------------GND
VCC-------------------5V
AO--------------------A0
DO-------------------悬空
温湿度传感器 ardiuno
GND------------------GND
VCC-------------------5V
AO-----10K上拉电阻----A1
关照传感器传感器 ardiuno
GND------------------------GND
VCC------------------------5V
SCL------------------------SCL
SDA------------------------SDA
ADD------------------------GND
添加了读取传感器数据的函数后,代码如下:
#include //温湿度
#include//IIC
#include
#define RET_OK 0
#define RET_ERR1
int BH1750address = 0x23;
byte buff;
#define DHTPIN A1
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
void setup() {
// put your setup code here, to run once:
pinMode(8, OUTPUT);
Serial.begin(115200);
dht.begin();
Wire.begin();//初始化IIC接口
while (!Serial) //
{
; // wait for serial port to connect. Needed for Leonardo only
}
//init WIFI module
WifiInit();
}
void WifiInit(void)
{
SendCmd("AT+CWMODE=3\r");
SendCmd("AT+RST\r");
//无线网络的SSID和密码
SendCmd("AT+CWJAP=\"hello-simon-30\",\"guajiguajiSIMONSEN2048\"\r");
SendCmd("AT+CIFSR\r");
SendCmd("AT+CIPSTART=\"TCP\",\"192.168.206.12\",8234\r");
//SendCmd("AT+CIPSTART=\"TCP\",\"183.230.40.33\",80\r");
SendCmd("AT+CIPMODE=1\r");
Serial.println("AT+CIPSEND\r");
}
void loop() {
float temp, hum;
int noise;
uint16_t light;
// put your main code here, to run repeatedly:
ReadTempHum(&hum, &temp);
noise = ReadVoice();
light = LightStrength();
//数据输出到服务器,此处为192.168.206.12的PC
Serial.print("temp:");
Serial.print(temp);
Serial.print("\thum:");
Serial.print(hum);
Serial.print("\tnoise:");
Serial.print(noise);
Serial.print("\tlight:");
Serial.println(light);
delay(2000);
//LedFlash();
}
void LedFlash(void)
{
digitalWrite(8, HIGH);
delay(500);
digitalWrite(8, LOW);
delay(500);
}
char SendCmd(String data)
{
Serial.println(data);//发送AT指令
while (1)
{
if (Serial.find("OK") == true)
{
LedFlash();
break;
}
Serial.println(data);
}
return RET_OK;
}
void ReadTempHum(float *h, float *t) //读取温湿度数据
{
*h = dht.readHumidity();
// Read temperature as Celsius
*t = dht.readTemperature();
// Read temperature as Fahrenheit
float f = dht.readTemperature(true);
// Check if any reads failed and exit early (to try again).
if (isnan(*h) || isnan(*t) || isnan(f))
{
Serial.println("Failed to read from DHT sensor!");
return;
}
}
int ReadVoice(void)//读取噪声数据
{
int temp;
temp = analogRead(A0);
temp = (long)100*temp/1024; //换算成分贝
//delay(1000);
return temp;
}
uint16_t LightStrength(void)//读取光照强度数据
{
int i;
uint16_t val=0;
BH1750_Init(BH1750address);
delay(200);
//Serial.println("");
if(2 == BH1750_Read(BH1750address))
{
val=((buff<<8)|buff)/1.2;
//Serial.print(val,DEC);
//Serial.println("");
}
delay(150);
return val;
}
int BH1750_Read(int address) //
{
int i=0;
Wire.beginTransmission(address);
Wire.requestFrom(address, 2);
while(Wire.available()) //
{
buff = Wire.read();// receive one byte
i++;
}
Wire.endTransmission();
return i;
}
void BH1750_Init(int address)
{
Wire.beginTransmission(address);
Wire.write(0x10);//1lx reolution 120ms
Wire.endTransmission();
}
编译后烧写到ardiuno板,重启,在PC端用网络调试工具查看数据传输结果,如下图所示:
表明各个传感器数据采集成功。
