Replacing a sensor costs about 180 bucks.
A sensor is a device capable of converting physical quantities (e.g., temperature, pressure, light, sound, etc.) into electrical or digital signals. Sensors are commonly used in measurement, monitoring and control systems, such as in automobiles, smart homes, medical devices and other fields. Common types of sensors include temperature sensors, pressure sensors, photoelectric sensors, acceleration sensors, sound sensors and so on.
Sensors are widely used in a variety of fields and industries, including industrial automation, healthcare, military, aerospace, environmental monitoring, and more.
Categorization of sensors:
1. Humidity sensor: measures the level of humidity in the air.
2, magnetic field sensor: used to detect the strength and direction of the magnetic field.
3, attitude sensor: can measure the direction of the axis of the object and tilt angle.
4, Smoke Sensor: can detect the smoke concentration and trigger an alarm or notification.
Sensor-related concepts:
1. Sensor network: a distributed system of many sensors that can collaborate with each other through wireless communication.
2. Sensor fusion: the integration and analysis of data from different types of sensors to improve the accuracy and reliability of measurement results.
3, human-computer interaction sensors: sensor devices that can recognize and respond to human movement, position, gestures and other information, such as Kinect body-sensing devices, Leap Motion gesture recognizer and so on.
4. In addition, in the development of sensor technology, smart sensors, MEMS (micro-electro-mechanical systems) sensors, nano-sensors and other emerging technologies have attracted widespread attention.
