Types of Air Conditioning Sensors

Temperature Sensors: Temperature sensors are one of the most common sensors in air conditioners, which can measure the temperature of the air conditioner in real time. According to the type of temperature sensor, it can be categorized into thermocouple temperature sensor, RTD temperature sensor, hybrid thermocouple-thermistor temperature sensor and so on.

Humidity Sensor: The humidity sensor can measure the humidity of the air conditioner in real time. According to the type of humidity sensor, it can be categorized into capacitive humidity sensor, inductive humidity sensor, resistive humidity sensor, and so on.

Air Quality Sensors: Air quality sensors are able to detect the cleanliness of the air around the air conditioner in real time, including PM2.5, carbon dioxide and so on. According to the type of air quality sensors, they can be categorized into photo ionization sensors, semiconductor sensors, etc.

Current Sensor: Current Sensor is able to detect the working current of the air conditioner in real time, which helps users to understand the working status of the air conditioner.

Working Principle of Air Conditioning Sensor

Working Principle of Temperature Sensor: Temperature sensors are usually made of materials such as thermistors or thermocouples, when the temperature changes, the resistance or conductivity of these materials will change, which in turn changes the charge of the sensor, thus realizing the measurement of temperature.

The working principle of humidity sensor: humidity sensor is usually made of materials such as capacitance or inductance, when the humidity changes, the capacitance or inductance of these materials will change, which in turn changes the charge of the sensor, thus realizing the measurement of humidity.

The working principle of the air quality sensor: air quality sensors are usually made of materials such as photo ions or semiconductors, when the air quality changes, the light absorption or photoconductivity of these materials will change, which will change the charge of the sensor, thus realizing the measurement of air quality.

How Current Sensors Work: Current sensors are usually made of semiconductor materials, and when the current changes, the conductivity of these materials changes, which in turn changes the charge of the sensor, thus realizing the measurement of the current.

Overall, Air Conditioning Sensors play a vital role in the operation of air conditioners, they can monitor the operating status of air conditioners in real time and provide users with accurate operating information. At the same time, the types of Air Conditioning Sensors are also being enriched and developed, and more new types of Air Conditioning Sensors will appear in the future.
