1.　　用18B20或AD590温度传感器作温度探头，采集温度数据并转换成BCD码在数码管上显示。

2.　　记录间隔可任意设定（1S到1h，步长1s），能按设定时间存储数据。

3.　　通过键回放温度和记录时间参数。

4.　　设定温度告警门限。

通过声、光告警显示

-1. 18B20 or the AD590 temperature sensor using the temperature probe, temperature data collected and converted into a BCD code in the digital tube display.

2. Recording interval can be arbitrarily set (1S to 1h, step 1s), able to store data according to set-up time.

3. Playback through the key records of temperature and time parameters.

4. Set the temperature alarm threshold.

Through sound, light and alarm display
