Headquartered in Shenzhen, China, Winpower Technology Co., Ltd. is a national high-tech enterprise and a Guangdong "Specialized & New" company dedicated to gas sensor solutions. Originating from Winpower Industrial's Technology Department, the company began developing NDIR sensors in 2003, was established in 2008, and obtained core invention patents for ultrasonic oxygen sensors.
Our core products span ultrasonic oxygen sensors, ventilator/HFNC oxygen sensors, oxygen generator sensors, microbaric oxygen chamber and plateau diffuse oxygen sensors, and dust particle flow sensors. The portfolio spans 21 oxygen sensor models across 7 application areas.
Winpower develops and manufactures two oxygen sensing technologies in-house. Measurement parameters, output interfaces and operating conditions differ by model — each product page and datasheet lists the specifications that apply to that model.

WinPower Tech — China (Class 9)
Winpower works with oxygen equipment manufacturers on sensor selection, mechanical integration and output configuration.
Sensor selection follows the application area. PSA concentrators, ventilator and HFNC gas mixing, oxygen chambers, gas analyzers and particle counters each map to specific models, and some models share a name across two firmware variants — the ordering firmware must be specified.
Whether you are designing a 1.5 kg shoulder-bag POC, a backpack-mounted system, or a wearable oxygen patch, our engineering team can co-develop a sensor solution tailored to your size, weight, and power (SWaP) targets.
From 3 L homecare units to 10 L clinical systems, our sensor portfolio covers the full stationary range with consistent form factors. Standard output is UART; RS-485 and 4–20 mA are available when paired with an adapter board. Only OCS-3F2.1 and OCS-3FRL2.0 provide a direct 0–2.5V analog output.
