Waterproof Digital Sensor for measuring Air and Water Pressure

Alps Alpine Corporation has started mass-producing the HSPPAD143A Waterproof Digital Pressure Sensor for wide-ranging applications in wearable devices and IoT products such as flow meters for essential utilities. The mass-production will help the growing demand of wearable devices which is expected to increase 200 million units by 2022. The HSPPAD143A Waterproof Digital Pressure Sensor features an expanded pressure measurement range of 300 – 2100hPa and a water-resistant design. This will enable the sensors to work in both low-pressure environments at altitudes up to 9,000 meters and high-pressure conditions down to 10 meters underwater allowing measurement in both open air and water with a single sensor.


The new HSPPAD143A Waterproof Digital Sensor comes in Surface Mount Type package and houses a dedicated, fully customized application-specific integrated circuit (ASIC) based on IC design. This helps the sensor to reduce the current consumption as low as 1.8μA in Low Power Mode which further helps devices to operate for lengthy periods. The HSPPAD143A sensor comes with built-in FIFO memory and it can be used in combination with a ready-made O-ring to simplify end-product design making it usable for a wide variety of purposes not limited to only wearable products or applications like pressure measurement in gas meters.


Specifications of HSPPAD143A Waterproof Digital Sensor:

  • Dimensions(W×D×H): 3.1mm×3.1mm×2.6mm
  • Current consumption: 1.8μA (in Low Power mode)
  • Noise: 2.6Pa (0.22m) (in High Resolution mode)
  • Pressure range: 300 - 2100hPa
  • Resolution: 2Pa/LSB
  • Measurement accuracy: +/- 2hPa

The samples of HSPPAD143A Waterproof Digital Pressure Sensor is available now and mass production has started. More information is available at Alps Website.
