Classification of Temperature and Humidity Sensors

A temperature and humidity sensor is a kind of sensor device equipped with humidity-sensitive and heat-sensitive elements, which can be used to measure temperature and humidity. Some have an on-site display, and some do not have an on-site display Temperature and humidity sensors are widely used in various fields of production and life because of their small size and stable performance.

Classification of temperature and humidity sensors

Analog temperature and humidity sensor

Temperature and humidity sensor temperature and humidity integrated sensor uses a digital integrated sensor as a probe and digital processing circuit to convert the temperature and relative humidity in the environment into corresponding standard analog signals, 4-20mA, 0-5V, or 0-10V. The temperature and humidity integrated analog sensor can transform the change of temperature and humidity value into the change of current/voltage value at the same time and can be directly connected with various standard analog input secondary instruments.

485 temperature and humidity sensor

The circuit adopts a microprocessor chip and temperature sensor to ensure the reliability, stability, and interchangeability of the product. The particle sintered probe sheath is adopted, and the probe is directly connected with the shell. The output signal type is RS485, which can reliably conduct distributed monitoring with the upper computer system and can communicate up to 2000 meters. The standard Modbus protocol supports secondary development.

Network temperature and humidity sensor

Network temperature and humidity sensors can collect temperature and humidity data and upload it to the server through Ethernet /wifi/GPRS. Make full use of the established communication network to realize long-distance data acquisition and transmission, and realize the centralized monitoring of temperature and humidity data. It can greatly reduce the construction volume and improve the construction efficiency and maintenance cost.

• Ethernet type

Ethernet temperature and humidity transmitters can collect temperature and humidity data and upload it to the server through Ethernet. The product makes full use of the established Ethernet communication network to realize long-distance data acquisition and transmission, and realize the centralized monitoring of temperature and humidity data. It can greatly reduce the construction volume and improve the construction efficiency and maintenance cost.

The product adopts a large screen LCD, which has the functions of double control of temperature and humidity, free setting of limit values, temperature, and humidity calibration by password, network interface data transmission, etc. the internal integrated alarm function module (buzzer or relay) can realize high and low-temperature alarm and high and low humidity alarm. The product adopts the original high-quality temperature and humidity measurement unit imported from Switzerland, which has the characteristics of high measurement accuracy and strong anti-interference ability, ensuring the excellent measurement performance of the product.

• WiFi type

WiFi wireless data transmission temperature and humidity transmitter can collect temperature and humidity data and upload it to the server through WiFi. Make full use of the erected WiFi communication network to realize data acquisition and transmission, to achieve the purpose of centralized monitoring of temperature and humidity data. It can greatly reduce the construction volume and improve the construction efficiency and maintenance cost.

• GPRS type

The temperature and humidity transmitter based on GPRS transmission only needs a mobile or Unicom SIM card to upload the collected temperature and humidity data to the server through the network base station. The monthly flow of GPRS communication is less than 30m.

The equipment is widely used in pharmaceutical vehicles, industrial control, building control, electricity, measurement and testing, warehouses, cold storage, and other industries.
