What is temperature and humidity sensor?

According to the research of physiologists, the temperature and humidity of the environment in which people live will directly affect the human body temperature regulation function and heat conduction effect. So that the quality of human body sensory fitness is reflected in the agility of thinking activities and the excellent mental state, thus affecting the efficiency of our study and work. After test analysis, the most suitable room temperature for the human body should be 18°C, and the humidity should be 40% to 60%. In people’s production and life, there are many different places and environments that have specific requirements for temperature and humidity. Therefore, reasonable temperature and humidity control has become a necessary means.

What is temperature and humidity sensor?

Temperature and humidity sensors commonly utilize integrated probes that incorporate temperature sensing elements to collect temperature and humidity signals. These signals are then processed through voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current, and reverse protection circuits. The processed signals are ultimately converted into current or voltage signals that have a linear relationship with temperature and humidity. Additionally, these signals can be directly outputted through main control chips such as 485 or 232 for further use and integration.

Food business

Changes in temperature and humidity will cause mildew in food materials, causing food hygiene and safety problems. Temperature and humidity monitoring can help relevant staff understand the status in real time and carry out timely control.


Paper packaging products are extremely sensitive to the temperature and humidity environment, and improper storage will seriously reduce the storage period of archives and data: and the use of wireless temperature and humidity sensor environmental monitoring system, plus exhaust fan, dehumidifier, end surface thermal resistance, can be long-term Maintain temperature, prevent pests, damp and other problems.

Greenhouse planting

The growth of plants grown in greenhouses is extremely strict with respect to temperature and humidity regulations. Under an unsuitable temperature and humidity environment, green plants will stop growing and even die. For example, using temperature and humidity sensors in conjunction with CO2 Sensor, O2 Sensor, etc. An intelligent greenhouse temperature and humidity video monitoring system controls the relevant main parameters in the vegetable greenhouse, thereby making the greenhouse more efficient.

Drug storage

According to relevant national regulations, drug storage must be controlled according to the relative temperature and humidity.

Tobacco industry

The temperature and humidity of cigarette raw materials must be well controlled during the fermentation process. In the case of a convenient on-site environment, a wireless temperature and humidity sensor can be used to monitor the temperature and humidity. In a complex environment, the temperature and humidity of the cigarette pack can be checked and controlled. , To prevent the occurrence of pests and diseases, if the operation is not done properly, it will cause a lot of damage to raw materials.

Industrial manufacturing

It is mainly used for ventilation and air conditioning, computer room monitoring, etc. Including the temperature of buildings, factories, etc., so that the ambient humidity can reach a comfortable natural environment.
