PH (potential of hydrogen) value determining wireless sensor for ultrasonic water treatment system

The utility model relates to a PH (potential of hydrogen) value determining wireless sensor for an ultrasonic water treatment system, which comprises a power module for power supply and a front PH value determining sensor module, and is characterized by further comprising an amplified filter circuit module, an A/D (analog/digital) conversion module, a wireless transmitting and receiving module and a single chip microcomputer control module, wherein the amplified filter circuit module is used for amplifying and filtering potential information detected by a front-end PH value determining sensor, the A/D conversion module is used for analog/digital conversion of the potential information detected by the front-end PH value determining sensor, the wireless transmitting and receiving module is used for wirelessly transmitting digital information after the conversion of the A/D conversion module, and the single chip microcomputer control module is used for controlling the A/D conversion module and the wireless transmitting and receiving module. The PH value determining wireless sensor for the ultrasonic water treatment system has the advantages that accurate and timely determination of PH values and treatment can be realized by the aid of front-end PH value sensing determination and amplification factor manual adjustment, and remote wireless data transmission can be realized by the aid of the wireless transmitting and receiving technology. Besides, the PH value determining wireless sensor is simple in structure, low in cost and convenient in use.
