What Is a Humidity and Temperature Sensor?
A humidity and temperature sensor is a device used to measure temperature and humidity and consists of a temperature sensor and a humidity sensor.
Uses of Humidity and Temperature Sensors
- Measurement of outside temperature and humidity
- Digital thermometers
- Sensors for air conditioning equipment such as air conditioners and heaters
- Sensors for managing automobile engines
- Sensors for smartphones, computers, etc.
- Industrial testing
Principle of Humidity and Temperature Sensors
1. Temperature Sensors
The following explains the principle of each type of resistance thermometer (RTD), linear resistor, and thermistor.
- Resistance Thermometer
Measures temperature by utilizing the property of semiconductors and metals to increase their electrical resistance as temperature rises. - Linear Resistors
Platinum or nickel-based resistance thermometers utilize the property of increasing resistance almost linearly with temperature. - Thermistors
Like resistance thermometers, thermistors measure temperature using the correlation between temperature and resistance but are classified into two types, NTC thermistors and PTC thermistors, based on the direction of resistance change with increasing temperature. -
- NTC thermistors: Resistance decreases as temperature rises
- PTC thermistors: Resistance increases at a specific temperature as temperature rises
2. Humidity Sensors
Humidity sensors are broadly classified into two types: resistance change type and capacitance change type.
- Resistance Change Type
The sensor has a structure in which a moisture-absorbing material bridges the circuit built into the sensor. As humidity increases and moisture is absorbed, the moisture-absorbing material lowers its resistance value, while dehumidification raises the resistance value. The electrical change in resistance is converted into humidity. - Capacitance Type
The sensor has a structure in which a moisture-absorbing material is sandwiched between two electrodes. The capacitance of the electrodes increases when moisture is absorbed and decreases when moisture is dehumidified. This change is converted to humidity.
3. IC Type Humidity and Temperature Sensors
Humidity sensors express measurement results as a percentage of water vapor content when the saturated water vapor content is 100%. Due to its temperature-dependent characteristics, it is called relative humidity. For this reason, they are often used in conjunction with temperature sensors and are collectively referred to as humidity and temperature sensors.
In addition to differences in measurement methods and configurations, there are two types of humidity and temperature sensors: sensor element only and IC type.
The IC type integrates the sensor element and measurement circuits such as A/D conversion into a single chip. When using a single sensor element, it is necessary to design the peripheral circuits according to the application, which is time-consuming and costly, but the integrated IC type can be used easily.
Also, when mounted on a board, the area can be reduced, resulting in miniaturization, low power consumption, and low cost.
Wireless Humidity and Temperature Sensors
Not only PCs and smartphones but also various devices are now connected to the Internet and can be linked together. This is known as the Internet of Things (IoT), and it is used for various services by enabling devices to exchange information, operate remotely, and collect data.
In particular, sensors play an important role in services and systems for remotely monitoring conditions and detecting abnormalities, and various types of sensors combined with wireless communication methods such as WiFi and Bluetooth, known as IoT sensors, have appeared.
Wireless temperature and humidity sensors are one of these sensors, and by utilizing these sensors, systems can be built to check and monitor temperature and humidity in remote locations.
They are used for temperature/humidity control and abnormality detection in places where people are not always present or visible, such as data centers, production lines, cooling facilities, warehouses, and greenhouses.
In addition, sensors are used in a variety of applications, such as window and door open/close detection, human and animal movement detection, home security services linked to home appliances, and monitoring services for the elderly.
