01Basic UnderstandingModel:HS-S21PName:Tilt SensorSeries:SensorDescription:This is a device used to detect the tilt angle or posture changes of an object. It contains tilt-sensitive components (such as ball switches or MEMS accelerometers) that convert the tilt state into electrical signals by sensing the direction of gravity or inertial changes, providing devices with “posture awareness” capabilities.Usage Scenarios:For example, tilt-controlled … Read more
01Basic UnderstandingModel:HS-S10PName:Fog SensorSeries:SensorDescription:This is a sensor device designed for detecting fog concentration. It has a built-in fog-sensitive element that converts the fog concentration signal into an electrical signal output by sensing the condensation state of water vapor in the air. It can monitor the fog level in real-time, providing environmental humidity and visibility perception capabilities … Read more
01Basic UnderstandingModel:HS-S20PName:Ambient Light SensorSeries:SensorDescription:This is a sensor device designed specifically for detecting ambient light intensity, equipped with a light-sensitive element(such as a photoresistor or photodiode), which can convert ambient light signals into electrical signals, providing real-time feedback on light intensity changes, enabling devices to have the ability to “perceive light”.Usage Scenarios:Linking curtains and lighting systems … Read more
A few days ago, a beginner asked me why, after running through all the examples on the STM32 development board—from lighting LEDs, handling buttons, serial communication to ADC acquisition—he felt he understood the code. However, when it came to starting a project, his mind went blank, and he had no idea where to begin. It … Read more
For embedded development beginners, the choice of the first development board directly determines the difficulty of getting started – choosing the right one can yield great results with minimal effort, while choosing the wrong one may lead to discouragement. This article compares five popular development boards: 51 Microcontroller, STM32, Raspberry Pi Pico, Raspberry Pi, and … Read more
