Fig. 1 is the process flow diagram of humiture collecting method of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Refer to Fig. 1, humiture collecting method of the present invention, the single-chip microcomputer based on joining and Temperature Humidity Sensor, comprise the following steps:

Step S1, resets to temperature sensor, and single-chip microcomputer sends N clock signal to Temperature Humidity Sensor, N >=9 and be integer; Stand-by period T after Temperature Humidity Sensor reception signal, then receive order next time; In the present embodiment, T is 11ms;

Step S2, single-chip microcomputer sends and measures temperature instruction to Temperature Humidity Sensor;

Step S3, Temperature Humidity Sensor to around carry out temperature survey, obtain temperature data;

Step S4, Temperature Humidity Sensor is converted to temperature physical quantity by temperature data by corresponding program and formula, shows and stores;

Step S5, single-chip microcomputer sends and measures humidity instruction to Temperature Humidity Sensor;

Step S6, Temperature Humidity Sensor to around carry out moisture measurement, obtain humidity data;

Step S7, Temperature Humidity Sensor is converted to humidity physical quantity by humidity data by corresponding program and formula, and according to temperature physical quantity and corresponding to the default humidity deviate of this temperature physical quantity, humidity physical quantity is revised, revised humidity physical quantity is shown and stored; Wherein, corresponding to each humidity deviate of each temperature physical quantity, be recorded in humidity deviation chart, this humidity deviation chart is stored in Temperature Humidity Sensor; Humidity deviate determines according to actual conditions, and for example, when humidity deviate is percentage, humidity physical quantity is multiplied by the result that humidity deviate obtains and is revised humidity physical quantity;

Step S8, Temperature Humidity Sensor is passed to single-chip microcomputer by the temperature physical quantity obtaining and revised humidity physical quantity, single-chip microcomputer by such as: Zigbee network, GPRS network etc. is sent to terminating machine by data, carries out analyzing and processing, obtain analysis result, realize various application.

Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
