Intelligent data acquisition circuit for water sports equipment

The invention discloses an intelligent data acquisition circuit for water sports equipment. An existing data acquisition circuit cannot be quickly and effectively placed on water sports equipment, occupies a large space, does not have a simple data storage circuit and is high in price. Aiming at the defects in the prior art, the invention provides an intelligent data acquisition circuit for water sports equipment, which comprises a four-way pressure sensor circuit, a six-axis inertial sensor circuit, a temperature and humidity sensor circuit, a power supply circuit, an SD (Secure Digital) card electric read-write circuit and a waterproof protection circuit. The four-way pressure sensor circuit, the six-axis inertial sensor circuit and the temperature and humidity sensor circuit provide input signals for the STM32 chip. The SD card electric read-write circuit receives a control signal of the STM32 chip and performs read-write action of the SD card; the power supply circuit supplies power to other circuits. Acc
