Abstract: Aiming at the problems of water quality monitoring sensor in traditional aquaculture water quality monitoring device,such as short working life and not fixed water quality information collection frequency,a new type of aquatic water quality testing platform based on PV is designed. Through the detection mode innovation design,innovative design of power supply mode,after the completion of water quality testing,driven by screw drive mechanism fixed at the bottom of the water quality sensor from the water,to achieve the non-detection of water quality sensors and detected water in the indirect contact,prolong the service life of water quality sensor,in the monitoring center preset water quality information collection When the detection time is reached,the screw transmission mechanism is lowered,so that the water quality monitoring sensor is deeply detected in the water body and the timing detection is realized. The PV array is used to power the units of the platform to make the platform structure more concise. Through Single-chip microcomputer（STM32F4,MAX813 watchdog chip） to control the Take-off and landing of screw transmission mechanism,ZigBee network data transmission. The experimental results show that the proposed scheme can meet the needs of aquaculture,prolong the life of water sensor by 80% and improve the detection accuracy by 35%,which provides a reliable scheme for the aquaculture field.
