With the acceleration of iteration and upgrade of intelligent products, as the "perception center" of intelligent products, the sensor needs to have stronger information processing capability to help developers quickly and efficiently complete application development.
Sensor principle: The sensor is a kind of detection device, which can capture the measured information and convert it into electrical signals or other forms of output according to certain rules, and can meet the requirements of information transmission, storage, display, recording, and control.
APM32F003 series MCU has the performance advantages of high dominant frequency, large capacity, wide temperature range, and high precision, and can meet the application requirements of miniaturization, systematization, digitization, and intelligence of sensors. Through the modular development of MCU+ sensors, it can effectively monitor, collect and process a large amount of parameter information, which helps optimize products and improve user experience.
Enhanced Information Processing Capabilities
Arm® Cortex®-M0+ core is adopted, with a maximum operating frequency of 48MHz. It supports efficient real-time processing of a large amount of data and information
·It provides on-board storage of 32Kbytes Flash and 4Kbytes SRAM, which can meet the signal acquisition and processing requirements of most sensors
· It conducts analog acquisition through 12-bit ADC (8-channel, supporting differential input), which can filter noise and other random signals, and realize dynamic high-precision real-time sampling and digital conversion output of useful signals.
·The power supply voltage is 2.0V~5.5V. Built-in power on/power-down reset and configurable voltage monitoring module.
·8kV ESD with strong anti-static interference capability
·The operating temperature range is -40~+105℃. It has a strong ability to adapt to the temperature, which can ensure the stable operation of the sensor in the environments of different temperatures
·It integrates HSI internal high-speed oscillator, with accuracy within ±3% in the full range, which helps to improve the sensitivity and stability of the sensor in collecting and processing information
Improve Application Diversification
·3-way UART, 1-way SPI, and 1-way I2C communication interfaces are integrated and can be used for node switching to make the sensor application configuration more flexible.
·16-bit general-purpose timer, 16-bit advanced timer, 8-bit basic timer, and other peripheral resources are integrated, so that they can comprehensively enhance the diversified control and connection of products and meet the diversified application needs of sensors, such as ultrasonic, atomization, magnetic rotation, temperature and humidity, UV and other module functions.
