It is easy to get "electric shock" everywhere in winter, and it is hot and sticky in summer. We all know the impact of humidity on our daily lives, but did you know that industrial production is also affected by humidity?

Recently, TE Connectivity (hereinafter referred to as "TE") released a white paper "The Importance of Humidity Control in Commercial and Residential Environments" , focusing on the accuracy of humidity measurement and the role played by sensor products.

@Manufacturers in various industries, here are some key facts about humidity you need to know:

Too high or too low humidity will have adverse effects on production and life

High indoor humidity can cause mold, poor air quality, and reduced productivity in industrial environments; on the other hand, low indoor humidity can also affect the processing and handling of many materials in factories and industrial environments, causing static discharge and affecting human health and comfort.

Our body's defenses are stronger at relative humidity levels >30%

Studies have shown that ¹ hour after coughing, the infectivity of influenza virus at 7-23% relative humidity is about 5 times that at >43% relative humidity

At relative humidity levels >30% or higher , there are fewer infectious flu viruses in the air, and flu is likely to be less contagious. Ideal workplace humidity can reduce fatigue, increase comfort, and improve employee mental acuity and performance.

As such, accurate humidity measurement and control is critical to preventing degradation and damage to commonly used products such as wood, metals, food, pharmaceuticals, fuels, paper products, and electronic components, as well as maintaining the health and productivity of employees.

Humidity Monitoring Key Link: HVAC System

Whether it is the home environment or the environmental regulation of industrial and commercial production, the HVAC system is an indispensable link, and has developed from a single temperature control to not only monitoring and controlling temperature, but also monitoring and controlling humidity, air quality and many other aspects.

HVAC units

Humidity sensor is one of the key components of HVAC system, used to monitor indoor and outdoor humidity. At the same time, humidity sensor is also a key element for monitoring and controlling equipment used to modify humidity.

Humidity sensors have evolved from simple resistive devices with limited measurement range and accuracy to fully digital models that can measure temperature and humidity with high accuracy and small offsets over a wide range of conditions.

Sensors in HVAC

In addition to measuring relative humidity, TE also has sensor solutions for measuring and regulating pressure, temperature, position, inclination and other parameters that are important for HVAC applications.

Humidity and Temperature Sensors: TE's humidity sensor family uses patented capacitive sensing technology that can sense relative humidity over the entire 0-100% range, react quickly to changing relative humidity levels, and recover quickly from condensation.

TE has introduced the new surface mountable humidity/temperature digital output combination sensor HTU31 , which uses a 2.5 x 2.5 x 0.9 mm package. These high-precision sensors are each calibrated and serialized for traceability; their typical accuracy is ±2% for relative humidity and ±0.2°C for temperature; they use a compact 6-pin DFN package, have a fast response time, and typical power consumption is only 3.78μW.

In addition to temperature and humidity sensors, TE also has a wide variety of pressure sensors and temperature sensors for HVAC systems.

TE Temperature Sensors for HVAC Applications

To make our indoor environment more comfortable and efficient, sensors, like general electronic devices, will continue to develop towards smaller package size, higher accuracy, fully digital output and lower power consumption.
