One.Overview
ATMEL company's ATMEGA128 high-performance CPU is used as the main control chip, large LCD display, RS485 communication interface, alarm output. Adopt standard plastic shell, digital temperature and humidity sensor.
The temperature measurement is carried out by the temperature probe under the instruction of the host, and the data is uploaded. The host data is analyzed after receiving the probe data, and the data is transmitted to the communication terminal. At the same time, the main engine is set according to the temperature threshold setting to carry out the corresponding overtemperature alarm and high-temperature alarm relay signal output.
