STMicroelectronics (ST) latest micro-pressure sensor equipped with advanced chip design and waterproof plastic formulations for manufacturers to bring high performance and fast delivery advantages, and further to the underwater measurement accuracy to a new level. Zhang orders from Samsung's latest high-performance wearable device - smart bracelet Samsung Gear Fit 2 Pro.
With the integration of smartwatches and wearable fitness trackers into their personal lives, users want to further expand the range of devices they use, such as recording more sports such as swimming, etc. To support these trends, Samsung's Next Generation Athletes Ring Gear Fit 2 Pro provides users with built-in GPS, continuous heart rate tracking, and more memory capacity, can complete many operations even without connecting the phone in this bracelet using the new ST of waterproof pressure The sensor LPS33HW, which is chemically resistant, is resistant to corrosion by chemicals such as chlorine, bromine or salt water and is suitable for use in swimming pools or the sea. It is also resistant to showers or detergents used in the shower or cleaning process.
The wearable device application is just the beginning of swimming, and the challenge of waterproof pressure sensors goes far beyond protecting electronic devices. The LPS33HW has the highest measurement accuracy on the market today because it will soon return to its highest accuracy after production But also help OEMs get the fastest delivery time Other brands of sensor lines take up to seven weeks to produce the highest accuracy, but the LPS33HW reduces the recovery time by half, thanks to the sensor's built-in high Performance processor and advanced waterproof plastic formula.
In addition to smart consumer electronics, devices such as industrial sensors and meters also benefit from the robustness and measurement accuracy of the LPS33HW, a 10bar waterproof pressure sensor capable of withstanding pressures up to 90 meters and RMS pressure noise of only 0.008mbar, which Allows altimeter, depth gauge, meteorological monitors to provide consistent, consistent measurements with annual drift of less than ± 1 mbar.
Production Line When the sensor is soldered to the board, the measurement accuracy will be affected and the ± 2mbar will be reduced. However, it will recover within 72 hours, which is much faster than similar waterproof pressure sensors.
The LPS33HW is now in volume production with a 3.3mm x 3.3mm x 2.9mm cylindrical metal package suitable for use with seals.
