حساس اوكسجين مع حساس سرعة تدفع الغاز في بورد واحد عالي الكفاءة وصناعي. حساس متطور يعمل بتقنية الموجات فوق الصوتية ultrasonic لتحسس نسبة الأوكسجين في الهواء او الغاز المار من خلال الحساس بنسبة 20 الى 95.6%. يقيس الحساس أيضا سرعة التدفق او ما يسمى بالـ Flow Rate بسرعة قصوى قدرها 10 لتر بالدقيقة الواحدة حيث يمكن ربطه عبر منفذ السيريل UART مع أي متحكم لقراءة نسبة الاوكسجين وسرعة التدفق. يستخدم في الكثير من التطبيقات أهمها التطبيقات الطبية مثل أجهزة التنفس الاصطناعي وأجهزة توليد الأوكسجين وأجهزة التخدير وغيرها من الأجهزة التي تحتاج الى قياس نسبة تركيز الأوكسجين علماً ان الحساس لا يحتاج الى اي معايرة فقد تمت معايرته مسبقاً في المصنع وتم فحصهُ.
