With the rapid development of science and technology, the sensor industry is changing, and office automation temperature sensors are constantly updated with the innovation of automation technology to meet people's temperature requirements in the office field. The office automation temperature sensor greatly reduces the labor time and workload by automatically detecting the temperature in the office area, and plays a huge role.

What is the measurement of office automation temperature sensor related to?
Office automation temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the heart of the temperature measuring device and there are many variations. Depending on the measurement method, it can be divided into two categories: a contact type and a non-contact type. Depending on the properties of the material sensors and electronic components, it can be divided into two types: thermal resistance and thermocouple.
The thermometer of the office automation temperature sensor achieves thermal equilibrium through conduction or convection so that the value of the thermometer can directly indicate the temperature of the measured object. Generally, the measurement accuracy is high. The thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range. However, larger measurement errors occur with moving objects, small targets, or objects with low heat capacity. Commonly used thermometers include bimetal thermometers, glass liquid thermometers, pressure thermometers, resistance thermometers, thermistors, and thermocouples. It has developed low-temperature thermometers that measure temperatures below 120K, such as low-temperature gas thermometers, vapor pressure thermometers, acoustic thermometers, paramagnetic salt thermometers, quantum thermometers, low-temperature thermal resistances, and low-temperature thermocouples. Low-temperature thermometers require small size, high accuracy, good reproducibility, and stability. The thermal resistance of carburized glass, which is produced by carburizing and sintering porous quartz glass, is a kind of temperature sensor element of the low-temperature thermometer, with which the temperature can be measured in the range from 1.6 to 300 K.
If the office automation temperature sensor wants to measure the true temperature of an object, it must correct the surface emissivity of the material. The surface emissivity of material not only depends on temperature and wavelength, but also on the surface state, coating film, and microstructure, so it is difficult to accurately measure. In automation work, it is often necessary to measure or regulate the surface temperature of certain objects utilizing radiation temperature measurement.
As the application of sensor-based technologies in industrial equipment, office automation equipment, and home appliances has proliferated, the demand for different types of sensor solutions is also rapidly increasing to meet multiple sensing functions. Application scenarios require fine-grained perception to achieve predictive maintenance functions. For example, printers need to detect the remaining amount of consumable materials and notify users in advance when they need to be replaced; vacuum cleaners need to manage the residual dust accumulated in the filter for effective cleaning. These features optimize the function of the device and increase user convenience. In short, office automation temperature sensors play a huge role in the office field.
