ABSTRACT
In order to meet the automatic management of greenhouses in agricultural modernization, this paper proposes a circuit system for greenhouse environment regulation. For greenhouses, maintaining the stability of the growth environment of crops is an important requirement. In order to properly control the greenhouse environment, low-cost single-chip microcomputers and some sensors can be used to complete this work well. The system can obtain the current environmental data in the greenhouse through the DHT11 sensor and the light sensor, and send control instructions to the relay through the single-chip microcomputer to control the external equipment to adjust the relevant environmental parameters in the greenhouse to maintain the stability of the environment.
