一般來講费就，傳感器數(shù)據(jù)可以分為離散型和數(shù)值型诉瓦。離散型傳感器記錄布爾值類型信息
如，開/關,正常/不正常力细。數(shù)值型傳感器要記錄的數(shù)據(jù)稍微復雜一些睬澡，如：31攝氏度，15毫米

對于數(shù)值型傳感器數(shù)據(jù),在程序中一般可以這樣描述

對于傳感器A（風扇）0 代表關眠蚂，1代表開,獲取到傳感器A 的數(shù)據(jù)為1時煞聪，代表風扇開。
對于傳感器B（溫度異常檢測器件）0代表不正常逝慧，1代表正常昔脯，獲取到傳感器B的數(shù)據(jù)為1時，代表溫度正常笛臣。

C語言描述上述邏輯可以這樣寫：

        struct sensor{
                const char *false_desc;
                const char *true_desc;
        }

        struct sensor sensor_a= {"關","開"};
        struct sensor sensor_b= {"不正常","正常"};

        int value = get_sensor_a();

        if(value == 0)
                printf("sensor a = %s\n",sensor_a->false_desc);
        else
               printf("sensor a = %s\n",sensor_a->true_desc);

        value = get_sensor_b();

        if(value == 0)
                printf("sensor b = %s\n",sensor_b->false_desc);
        else
                printf("sensor b = %s\n",sensor_b->true_desc);

當項目中傳感器的數(shù)量和類型較多時云稚，代碼可以這樣修改

        void register_sensor(int sensor_id,int sensor_type)
        {
                register();
        }

        int find_sensor_type_by_id(int id)
        {
                return type;
        }

        struct sensor_desc{
                const char *false_desc;
                const char *true_desc;
        }
        static struct sensor_desc *find_sensor_desc_by_type(int sensor_type)
        {
                return  &sensor_desc;
        }

        void print_sensor_value(int sensor_id,int value)
        {
                int sensor_type = find_sensor_type_by_id(sensor_id);
                struct sensor_desc *desc = find_sensor_desc_by_type(sensor_type);

                if(value ==0)
                        printf("value=%s\n",desc->false_desc);
                else
                        printf("value=%s\n",desc->true_desc);

        }


        int main()
        {
                register_sensor()


                while(1){
                   int v = get_sensor_value(sensor_id);
                        print_sensor_value(sensor_id,v);
                }
        }

這樣我們分離了傳感器的描述信息和值信息。對于數(shù)值型傳感器值信息和描述信息也可以這樣分離沈堡。
