Innovation Backed by Rigorous Testing
Recently, a student research team from Peking University, under the guidance of their professors, successfully developed a new type of temperature sensor designed to improve stability and sensitivity under extreme environmental conditions. To verify the reliability of their innovation, the team partnered with DHT®, utilizing our advanced constant temperature and humidity chambers for comprehensive performance testing.
This collaboration represents not only a perfect integration of academic research and industrial application but also a strong testament to DHT®’s commitment to supporting technological innovation and fostering engineering talent.
Peking University’s Technological Breakthrough
The temperature sensor developed by the Peking University team marks a significant step forward in the field of Industrial IoT. Characterized by high precision, low power consumption, and miniaturization, the sensor is expected to find applications across intelligent manufacturing, medical devices, environmental monitoring, and other critical sectors.
“We needed to verify the sensor’s stability and accuracy under drastic temperature fluctuations, as this directly impacts its reliability in real-world applications,” said the team leader.
While the students had already completed fundamental functional testing, proving the sensor’s adaptability in real-world scenarios required specialized environmental reliability testing. This was the primary reason they sought the support of DHT®’s professional testing equipment.
The Critical Role of DHT® Chambers
DHT® provided the team with its latest series of constant temperature and humidity chambers, capable of precisely simulating a wide range of conditions—from extreme low temperatures to high heat—while maintaining stable humidity levels.
The testing program included three key stages:
-
Cold-start testing within a range of -40℃ to +25℃, evaluating response performance in extremely low temperatures.
-
Thermal stability testing between +25℃ and +85℃, assessing accuracy under high-temperature conditions.
-
High-humidity endurance testing, ensuring long-term operational stability.
“We paid special attention to how rapid temperature changes affect sensor accuracy,” explained one of the testing engineers. “The chamber’s ability to achieve temperature shifts at a rate of 5℃ per minute provided us with invaluable data.”
Testing Parameters and Performance Validation
Throughout the process, DHT® chambers demonstrated exceptional performance. Temperature was controlled with an accuracy of ±0.5℃, and humidity deviation was maintained within ±2% RH, ensuring both reliability and repeatability of results.
The team established several critical performance metrics: sensor response time across varying temperature points, measurement accuracy, power consumption variations, and long-term stability. Each metric was tested under rigorously controlled conditions and repeated multiple times to ensure statistical significance.
“What impressed us most was the chamber’s environmental uniformity,” a student team member commented. “Temperature variations across different points within the chamber were less than ±1℃, providing us with highly consistent testing conditions.”
Academic-Industrial Collaboration Driving Innovation
This project also highlights DHT®’s commitment to supporting academic research. Beyond providing access to advanced testing equipment, DHT® assigned a dedicated technical team to work alongside the students, helping optimize testing protocols and interpret results.
“Collaborating with the Peking University team gave us invaluable feedback,” said the DHT® Technical Director. “Their innovative thinking and rigorous approach were truly impressive, and some of the testing scenarios they proposed even inspired us to improve our own product design.”
This kind of collaboration between academia and industry is becoming a vital driver of technological advancement—where universities contribute pioneering ideas and technologies, while industry provides real-world platforms and experience to accelerate practical application.
