1. RS422 communication principle: (1) RS422 working mode: RS422 supports full-duplex communication mode, that is, data can be transmitted bidirectionally at the same time, that is, two pairs of differential lines are used for sending and receiving respectively, which improves the efficiency and flex...
Read MoreIf the communication between the sensor module and the user system is carried out using UART, SPI or IO methods, generally, the interface voltage level of the sensor module is 3.3V, and the voltage level of the user system is also 3.3V. Usually, a direct connection method is feasible. However, if th...
Read MoreThe voltage output type sensor typically outputs a voltage range of 0-5V or 0-10V. If we choose not to use an external ADC conversion chip due to cost considerations but instead sample the ADC module within the MCU chip, but as the voltage range of the AD acquisition in STM32 is 0-3.3V, in this case...
Read More1. Working Principle and Types of Acceleration Sensors An acceleration sensor is a common type of sensor that can measure the acceleration and tilt angle of objects, and is widely used in industries, healthcare, sports, and other fields. Acceleration sensors typically consist of sensing elements, si...
Read MoreThe main reason for choosing dual power supplies for sensors is to meet the requirements of signal integrity, circuit operating conditions, and measurement accuracy. This includes the following aspects: 1. Handling bidirectional signals (AC signals) Some sensors (such as vibration, sound, and accele...
