Abstract

Hatching systems requiring high control accuracy of temperature and humidity. Particularly temperature, small temperature change will significantly affect hatching time and hatching rate. This article design the hardware circuit based on the SCM. Using digital single bus temperature sensor DSl8820 to improve accuracy of temperature measurement, using HM1500 to build frequency detection circuit of humidity inside the incubator, design the output control circuit based on photoelectric coupler TLP521, power-driven IC ULN2803 and relay.
