The NPS300x is a family of compact, differential high precision pressure sensor with an I2C and SPI digital interface. It covers operating range from -500 Pa to 500 Pa up to 0 to 5 kPa with a very high sensitivity of 0.125 Pa/LSB and a 3 Pa accuracy. Due to its low power with current consumption down to 3.15 µA in measurement mode and interrupt capabilities, it is a perfect fit for battery powered applications.
Standard version (NPS300x)
The standard version is suitable for medical applications such as e-inhalers (i.e. alcohol breath test, drug delivery, etc.), continuous positive air pressure (CPAP) masks, or other breath-related medical devices. Ultra-low power capabilities combined with the smallest market footprint and very good pressure repeat-ability make the NPS300x family the perfect component for your device.
Enhanced version (NPS300xE)
The enhanced version family has been specifically developed for improved pressure accuracy and offset stability over life. This makes the product family ideal for industrial applications such as smart filter, fan control regulation, ventilation systems (humidity extractor, HVAC), and appliance applications such as liquid level measurement (i.e. for washing machine, coffee machine, dishwasher, etc.), vacuum cleaners (full bag detect, smart filter, smart suction control, etc.) and air purifiers.
