Real-time monitoring system for environmental soil humidity data

The invention discloses a real-time monitoring system for environmental soil humidity data. According to the soil humidity online monitoring system, the data acquisition module completes online acquisition and conversion functions of the capacitance value of the soil humidity sensor through the PCAP01 chip, the real-time online monitoring function of the soil humidity is achieved through the high-precision digital conversion chip PCAP01, and experimental research results show that the soil humidity online monitoring system is high in testing precision, good in stability and high in efficiency; the real-time performance is high, whether the soil water reaches the field moisture capacity or not can be rapidly detected in the irrigation period, whether the soil water is reduced to the crop wilting coefficient or not can be accurately detected in the consumption period, and a scientific and effective decision is provided for the irrigation opportunity. Therefore, wider application and development prospects are br
