Abstract

Nursery sheds have the characteristics of staying closely, quantity, parameter changing slowly, a small amount of data, so the article presents a distributed centralized monitoring system based on a short-range radio transceiver IA4421 chip. The front-end system circuit choose single-chip STC89LE52RC as the control of the core, complete a humidity sensor HS1101, the temperature sensor DS18B20 circuit and IA4421 peripheral circuit design, method of CRC, after completing front-end systems and hardware design of data center, design gives the software design, the corresponding flow chart and some instances.
