July 24, 2025, Shenzhen — Winpower Technology Co., Ltd. is proud to announce the release of its new-generation Limiting Current Oxygen Sensor Module GSTB-400H V1.2. Designed for high precision, fast response, and robust environmental adaptability, this sensor module provides a reliable solution for oxygen concentration measurement in industrial monitoring, medical equipment, environmental detection, and more.  

Key Features  

1. High-Precision Measurement  

- Detection range: 0.1%–40% oxygen (customizable for other concentrations)  

- Resolution: 0.01%, accuracy ±1% FS (@ -40°C to +85°C)  

- Built-in temperature, humidity, and pressure compensation for enhanced accuracy.  

2. Fast Response & Stability  

- Response time (t90) < 5 seconds, warm-up time just 60 seconds.  

- Wide operating temperature range (-40°C to +85°C) for harsh environments.  

3. Multi-Function Integration  

- UART communication interface (3.3V logic) for real-time oxygen, temperature, humidity, and pressure data.  

4. Long Lifespan & Low Power Consumption  

- Service life ≥ 5 years, typical power consumption 1.6–3.6W (transient ≤5W).  

- Diffusion-based sampling, eliminating the need for external pumps.  

5. Flexible Calibration & Protocol Support  

- Supports single-point calibration (e.g., 20.9% ambient air).  

- Hex-format communication protocol for easy integration and development.  

Applications  

- Industrial Safety: Combustible environment monitoring, exhaust gas analysis.  

- Healthcare: Oxygen concentrators, ventilators.  

- Environmental Monitoring: Air quality assessment, laboratory equipment.  

- IoT Devices: Portable detectors, smart agriculture sensors.  

Technical Specifications  

- Power Supply: 12V ±0.5V DC  

- Dimensions: 58.27mm × 42.11mm × 20.3mm  

- Communication: UART (9600bps, no parity)  

- Environmental Resistance: Storage temperature -40°C to +100°C.
