如何使用Contiki-OS读取温度,湿度和光线测量?
题
我想知道如何用Contiki程序测量温度,光线和湿度。
我正在使用Telosb Mote(Sky Mote),因此这三个传感器集成在MOTE本身中。
ps:我正在使用contiki-os 2.7
解决方案
为了使用光和温度传感器,您需要添加下一个:
#include "dev/sht11-sensor.h"
#include "dev/light-sensor.h"
.
然后,您可以使用下一个功能:
static int
get_light(void)
{
return 10 * light_sensor.value(LIGHT_SENSOR_PHOTOSYNTHETIC) / 7;
}
static int
get_temp(void)
{
return ((sht11_sensor.value(SHT11_SENSOR_TEMP) / 10) - 396) / 10;
}
.
例如,显示这些传感器的值的最小应用是:
#include "contiki.h"
#include "dev/sht11-sensor.h"
#include "dev/light-sensor.h"
#include "dev/leds.h"
#include <stdio.h>
//Declare the process
PROCESS(send_sensor_info_process, "Print the Sensors Information");
//Make the process start when the module is loaded
AUTOSTART_PROCESSES(&send_sensor_info_process);
/*---------------------------------------------------------------------------*/
static int
get_light(void)
{
return 10 * light_sensor.value(LIGHT_SENSOR_PHOTOSYNTHETIC) / 7;
}
/*---------------------------------------------------------------------------*/
static int
get_temp(void)
{
return ((sht11_sensor.value(SHT11_SENSOR_TEMP) / 10) - 396) / 10;
}
/*---------------------------------------------------------------------------*/
//Define the process code
PROCESS_THREAD(send_sensor_info_process, ev, data)
{
PROCESS_BEGIN();
SENSORS_ACTIVATE(light_sensor);
SENSORS_ACTIVATE(sht11_sensor);
printf("Light: %d \n", get_light());
printf("Temperature: %d \n", get_temp());
PROCESS_END();
}
