What are the temperature and humidity sensor?

A temperature and humidity sensor is a device that can simultaneously measure the temperature and humidity of an environment. It usually consists of a temperature sensor and a humidity sensor, either as two separate sensors or as a composite sensor integrated into a single unit. Temperature and humidity sensors are capable of converting physical quantities (temperature and humidity) into electrical signals that can be read and displayed by data loggers, microcontrollers, or other display devices.

Temperature and humidity sensors are used in a wide variety of applications including, but not limited to, agriculture, industry, meteorology, environmental protection, building management, food storage, healthcare, home automation, and more.

How Temperature and Humidity Sensors Work

The working principle of temperature and humidity sensors is usually as follows:

- Temperature Sensors: Temperature can be measured in a variety of ways, such as thermocouples, thermistors (NTC or PTC), resistance temperature detectors (RTDs), and so on. These sensors measure temperature by changes in resistance or voltage caused by changes in temperature.

- Humidity Sensors: Capacitive, Resistive and Dewpoint are common. Capacitive humidity sensors detect humidity by measuring changes in the dielectric constant of the medium (usually air), while resistive humidity sensors work by measuring the effect of humidity on the resistance of the sensor material.

 Applications of Temperature and Humidity Sensors

Temperature and humidity sensors have a wide range of applications in many fields, the following are some of the main application scenarios:

1. Agricultural field: In greenhouses, greenhouses and other facilities, temperature and humidity sensors are used to monitor the environmental conditions of crop growth, adjust the temperature and humidity in a timely manner, and improve crop yield and quality.
