Embedded Multi-Function Smart Hygrothermograph
This unique digital hygrothermograph, which is smaller than traditional hygrothermographs, displays temperature, humidity, and the time. The data is displayed on a large 32-segment LCD. If the temperature or humidity reaches a level beyond the preset limits, an alarm triggers a flashing light and audible buzzer. The digital clock accommodates up to five different alarm settings. For added convenience, the data can be transmitted to a PC and stored automatically. The system is built around an H8/38024 microcontroller, which reads time information from a real-time clock and I²C bus.
