Sensors, a high-tech that emerged in the mid-20th century, have gradually gained prominence across all sectors with the rapid development of the information industry. Today, sensors have been deeply integrated into our production and daily lives—they can be found in smartphones and smart homes, robots and autonomous driving systems, and even in an increasing number of medical applications. Going forward, as the intelligent era advances further, sensors will only grow more crucial.

Technological progress has brought convenience to production and daily life. Just like the prevailing "Internet Plus" model, sensors are demonstrating great potential value in traditional industries. For instance, industries such as petroleum and petrochemicals, coal mining, and animal husbandry utilize oxygen sensors, carbon monoxide sensors, hydrogen sulfide sensors, ammonia sensors, chlorine sensors, ethylene oxide sensors, temperature sensors, and more.

In the past, the poultry hatching industry lacked the concept of constant temperature and humidity control. While many recognized the importance of temperature, they believed that incubation equipment and egg quality were the sole determinants of hatching rates. In reality, the environment of the hatchery exerts a significant impact on poultry production and incubation. It is understood that many hatcheries do not treat the air entering the incubation equipment and directly discharge waste gas into the hatching workshop, leading to the recirculation of waste gas back into the equipment. Additionally, due to weather variations, the temperature and humidity of the incoming air fluctuate greatly, resulting in unstable air quality inside the equipment and thereby endangering the survival and development of livestock and poultry embryos.

This underscores the importance of environmental monitoring in hatcheries. First and foremost is temperature and humidity control: hatcheries have strict requirements for these two factors, and their needs vary across different stages according to the progress of incubation, breeding processes, and weather changes. Temperature and humidity sensor monitoring technology enables automatic monitoring and regulation of these conditions. Gas sensors can also be used to monitor gas concentrations in the facility; when hazardous gas levels exceed the threshold, ventilation and air exchange measures can be activated to reduce concentrations.

With the continuous progress of society, traditional agricultural production methods can no longer meet the demands of modern civilization, giving rise to the development of smart agriculture. Sensors play a pivotal role in integrating Internet of Things (IoT) technology with traditional agriculture. In the past, agriculture relied heavily on favorable weather conditions. Now, sensors allow us to largely break free from the constraints of natural factors like weather, enabling remote and scientific monitoring in fields, greenhouses, aquaculture, and animal husbandry. Sensor monitoring technology can also enhance agricultural disaster resistance and risk management capabilities through scientific analysis, thereby boosting agricultural productivity.

A wide variety of sensors are applicable in agriculture. For example, temperature and humidity sensors monitor ambient conditions; soil moisture sensors analyze the water requirements of crops; light sensors detect and regulate light intensity to ensure uniform illumination for plants; carbon dioxide sensors control CO₂ concentrations, and so on.

Similarly, related sectors such as forestry and flower cultivation can also leverage sensors to drive the intelligent transformation of traditional industries.

Sensors are a centerpiece of current technological development—innovations in sensor technology are constantly emerging, and their application outcomes are flourishing across the board. As technology marches forward, we hope that modern technology will drive the development of traditional industries hand in hand, translating technological achievements into tangible benefits for the general public.
