Soil Moisture Monitoring System Based on RS485 Bus

Abstract:

In order to greenhouse plants for automatic irrigation operation, was designed based on the soil moisture monitoring system of RS 485 bus system, the oscillation frequency of the clock oscillation circuit, and a main chip count, frequency signal PC software will be the main chip records show, form curve, thus providing the basis of the data for the automatic irrigation, experimentally tested for a long time, the system performance is stable and reliable.
