It seems you might have some confusion. You probably mean "Types of Arduino Sensors". Here are some common types of Arduino sensors:
-
Environmental sensors:
- Temperature sensors: Such as the DS18B20, which can measure the ambient temperature. It's widely used in applications like weather stations and temperature - controlled systems.
- Humidity sensors: For example, the DHT11 or DHT22. These sensors are used to measure the relative humidity in the air, which is important in environments where humidity control is crucial, like greenhouses or data centers.
- Air quality sensors: The MQ - 135 is a common air quality sensor that can detect various gases such as ammonia, sulfur dioxide, and carbon monoxide. It's useful for monitoring air quality in homes, offices, or industrial settings.
-
Motion sensors:
- PIR motion sensors: Like the HC - SR501. These sensors detect infrared radiation emitted by moving objects, typically used for applications such as automatic lighting control, security systems, and occupancy detection.
- Ultrasonic sensors: The HC - SR04 is a popular ultrasonic sensor. It measures the distance to an object by emitting ultrasonic waves and measuring the time it takes for the echo to return. It can be used in robotics for obstacle detection and in applications like parking sensors.
-
Light sensors:
- Photocells or LDRs (Light - Dependent Resistors): The resistance of an LDR changes with the intensity of light falling on it. It's commonly used in applications such as automatic street light control, where the light turns on when the ambient light level is low.
- Color sensors: The TCS34725 is a color sensor that can detect the color and intensity of light. It's used in applications like color sorting, art - related projects, and in some consumer electronics for color - based interactions.
-
Force and pressure sensors:
- Force - sensitive resistors (FSRs): These sensors change their resistance when a force is applied to them. They can be used in applications such as touch - sensitive interfaces, robotic grippers to detect the force of gripping, or in pressure - sensitive mats.
- Pressure sensors: The MPX5700 is a pressure sensor that can measure various pressures, including air pressure and liquid pressure. It's used in applications like weather stations to measure atmospheric pressure, in automotive systems to monitor tire pressure, and in industrial processes to monitor fluid pressure.
This is just a basic overview, and there are many other types of sensors available for use with Arduino, each serving specific purposes in different projects.
