For the design of set-unit hardware circuit, the module uses battery power supply, its energy is limited, so the module should choose low working voltage and low power consumption peripheral circuit devices. P89LPC933 microcontroller from Philips is selected as the acquisition module, and its working voltage is 2.4 ~ 3.6V. P89LPC933 single chip microcomputer adopts high-performance processor structure, instruction execution time only 2 ~ 4 clock cycles, 6 times the standard 80C51 device; It is used in many embedded systems with the advantages of strong anti-interference ability and low power consumption. At the same time, P89LPC933 integrates many system-level functions, such as an 8-bit, 4-way stepwise analog analog/digital conversion module and a DAC module, 400 kHz byte mode I2C communication port, SPI interface, keyboard interrupt, on-chip watchdog timer. This can greatly reduce the number of components, reduce the circuit board area, and reduce the cost of the system, so it is suitable for many requirements of high integration, low cost occasions, can meet various performance requirements. In order to reduce the power consumption of the microcontroller, the module adopts a low-frequency external 32.768 kHz crystal oscillator with a working voltage of 3V. After the collection is complete, the controller disables the A/D function and enters idle mode.
