In today’s smart buildings, agricultural greenhouses and industrial facilities, maintaining optimal air quality is no longer a luxury but a necessity. Carbon dioxide (CO₂) levels directly impact human productivity, crop health and overall environmental safety. Therefore, selecting a reliable, high-precision sensor forms the cornerstone of any successful monitoring system.

We are proud to introduce our advanced CO₂, temperature and humidity sensor series. Engineered to deliver outstanding accuracy and seamless integration, these devices are built to meet the stringent requirements of modern environmental monitoring.

Advanced Sensing Technology

Our sensors adopt the Non-Dispersive Infrared (NDIR) principle to detect atmospheric CO₂ with exceptional stability and an ultra-long service life of over 5 years. Unlike conventional sensors, NDIR technology is unaffected by oxygen concentration and features built-in temperature compensation. This guarantees highly accurate CO₂ readings (measuring range: 0 to 6000 ppm) amid any environmental fluctuations. Moreover, the integrated probe also measures temperature from -40℃ to +80℃ and humidity from 0 to 99.9% RH, making it a truly versatile monitoring tool.

Flexible Connectivity: Dual Options of RS485 and LoRaWAN

We understand every project has unique connectivity requirements. Hence, we offer flexible communication choices:

• RS485 Output: Ideal for local wired industrial integration, ensuring stable data transmission in harsh environments.
• LoRaWAN Protocol: For long-range wireless deployment, our LoRaWAN sensors leverage spread-spectrum modulation to achieve ultra-long-distance communication. Compliant with standard LoRaWAN protocol, they are perfect for smart city networks and large-scale self-organizing sensor arrays.

Intelligent Active Early Warning Mechanism

A superior sensor does more than just collect data — it enables actions based on data. Our devices support emergency reporting. You may preset upper and lower threshold limits for gas concentration. Once CO₂ levels exceed these thresholds, the sensor instantly reports abnormal data and can even trigger external alarm systems via DO transistor output linkage.

In addition, the device supports remote configuration. Downlink commands can be used to adjust reporting intervals, data acquisition cycles and even perform zero-point calibration.

Robust Build & Quality Certifications

Featuring a sturdy ABS housing, the sensor is designed for wall-mounted installation in tough environments. It is CE and RoHS certified to comply with international standards. We also provide OEM & ODM customization services to perfectly match your brand and specific application requirements.
