The invention discloses an artificial cultivation water temperature and PH value monitoring system comprising a temperature detection circuit, a PH value detection circuit, a signal conditioning circuit, a DSP controller and a wireless receiving circuit. According to the system, the PH value and temperature information of the field work environment is acquired through sensors and filtered through the signal conditioning circuit, then voltage conversion is performed through MAX186CCPP12 bit A/D data conversion module, then data processing and acquisition are performed through the DSP controller of which the model number is TMS320LF2402, field data displaying of the processed data can be directly performed through a display circuit and the data are transmitted to an upper computer through a wireless transmitting module, and the upper computer and a lower computer mutually transmit the information through the wireless communication mode. When the data in the environment exceed the preset value, the system can emit alarm information, and the historical data are stored in the upper computer. The system has the advantages of being less in peripheral circuit, great in reliability, great in stability, high in sensitivity and fast in analysis so as to have wide market application prospect.
