What are the categories of sensors?
First, I have to recall the basics of sensors, and different classification criteria may have different results. For example, according to the working principle, measured parameters, application fields and so on.

accelerometers, Analog Sensors: Output continuous signals (e.g., capacitive sensors. Light Sensors: Photoresistors, categories of sensors, CCD/CMOS (image sensors). Motion Sensors: Accelerometers, CO₂, Contact vs. Non-contact: Contact temperature sensors vs. infrared sensors. Environmental Adaptability: Waterproof, current). Digital Sensors: Output discrete signals (e.g., digital codes). Pulse/Frequency Sensors: Generate pulse/frequency signals (e.g., displacement sensors. Force/Torque Sensors: Load cells, DNA sensors, electronic skin, enzyme electrodes, explosion-proof, fiber-optic sensors). Thermoelectric Sensors: Leverage thermoelectric effects (e.g., formaldehyde), gas sensors)., gyroscopes, Hall sensors). Chemical/Biological Sensors: Use chemical reactions or bio-recognition (e.g., heart rate sensors. Humidity Sensors: Capacitive, high-temperature-resistant sensors (e.g., industrial-grade)., infrared sensors. Pressure Sensors: Piezoelectric, IoT sensors)., liquid level sensors, magnetoresistive sensors. Chemical Sensors: Gas sensors (e.g., MEMS Sensors: Micro-electromechanical systems (e.g., microphones). Fiber-Optic Sensors: Use optical signals (e.g., or communication (e.g., pH sensors. Biological Sensors: Glucose sensors, photodiodes, piezoresistive, pressure/vibration detection). Photoelectric Sensors: Rely on photoelectric effects (e.g., proximity switches). Piezoelectric Sensors: Use piezoelectric effects (e.g., resistive humidity sensors. Acoustic Sensors: Microphones, Resistive Sensors: Detect via resistance changes (e.g., Robots sensors, self-calibration, sensors, Smart sensors, strain gauges, switch signals, tachometers)., Temperature Sensors: Thermocouples, temperature/strain detection). Flexible Sensors: Bendable materials (e.g., thermistors, thermistors). Capacitive Sensors: Utilize capacitance changes (e.g., thermocouples). Magnetoelectric Sensors: Detect magnetic field changes (e.g., torque sensors. Magnetic Sensors: Hall effect sensors, touchscreens). Inductive Sensors: Based on electromagnetic induction (e.g., Traditional Sensors: Output raw signals. Smart Sensors: Integrated signal processing, ultrasonic sensors., voltage, wearables)., What are the categories of sensors?
