The demonstration device of solar-powered water-saving automatic irrigation,which was controlled with AT89S52,could automatically detect the temperature and humidity inside the experiment box.It was equipped with a wireless transceiver module NRF24l01 in the control terminal,which could display the current temperature and humidity value in real time.When the temperature and humidity exceeded the upper limit,NRF24l01 module could send interrupt signal and switch the water pump to realize automatic control of temperature and humidity.It could also inform the user the real situation inside the greenhouse.The user could also do some operations to reduce the temperature and the humidity in experiment box.
