TE Connectivity has added two new wireless pressure sensors to its portfolio: a 65xxN wireless pressure sensor, for short-range coverage, and 69xxN wireless pressure sensor, for long-range coverage. Designed for periodic condition monitoring, the 65xxN wireless pressure sensor leverages BLE (Bluetooth low energy) 5.3 communications, to support localized data collection and transmission. Given the widespread presence of Bluetooth in […]

What pressure levels impact the eardrum?
Previous blogs have discussed human body pressures including blood pressure and optical pressures. However, there are several more pressure measurements for different body locations that need to be considered. For example, the pressures created by different situations on the human ear, and specifically the eardrum, are critically important. High noise environments such as industrial machinery […]
How is sensing used to detect glaucoma?
The term glaucoma is used to describe a group of eye diseases. In addition to damaging the eye’s optic nerve, glaucoma can result in vision loss and even blindness. About 3 million Americans have glaucoma, but the disease affects more than 67 million people worldwide and is the second leading cause of blindness. Glaucoma occurs […]
What is normal blood pressure?
If you answered 120 over 80 mmHg, you are using criteria that is over 20 years old. As reported in a 2003 article, revised guidelines categorized normal blood pressure as <120/80 mmHg. Since the measurements are meant to lower the risks from not recognizing what is often called the silent killer – high blood pressure […]
Pressure sensors for medical application offer fast response time
Superior Sensor Technology announced two new CP Series pressure sensors for Positive Airway Pressure (PAP) devices used in sleep apnea, COPD, Asthma, and home ventilator applications. Based on Superior Sensor’s highly integrated CP Series dual pressure sensor architecture, the new CP202 and CP302 closed-loop control functionality and overpressure indicator enable manufacturers to easily upgrade their PAP […]
How is sensing involved in deep sea exploration?
As the recent loss of OceanGate’s Titan tourist vessel has revealed, exploring in the ocean’s depths is very risky business. To see the Titanic up close and personal, the Titan would have to travel to a depth of 3,800 m (12,467 ft), where the pressure is 382.45 bar (5,547.14 psi or 38,246.06 kPa). It turns […]
Waterproof pressure sensor provides digital memory and connunications
STMicroelectronics has introduced the market’s first MEMS water/liquid-proof absolute pressure sensor with a declared 10-year longevity program for the industrial market. ST’s new ILPS28QSW sensor comes in a sealed, cylindrical, surface-mountable package. It features a ceramic substrate that provides high resistance to liquid permeability and a robust potting gel, proven in automotive applications, to protect the […]
When to use sound pressure and when to use sound intensity measurements
Sound pressure, sound intensity, and sound power are three different ways to quantify sound. This FAQ begins by defining each one, looks at various types of measurement techniques that can be used to quantify them, presents a range of international testing standards for measuring sound, looks at instruments used for measuring sound pressure and intensity, […]
BLE for TPMS addresses smarter, connector vehicle tires
Sensata Technologies announced it has developed a new Bluetooth Low Energy (BLE) Tire Pressure Monitoring System (TPMS) for vehicle OEMs to help improve vehicle safety and performance. Interest in BLE TPMS is on the rise as vehicles become more connected, electrified, and autonomous. While common in consumer applications like speakers and headphones, BLE is […]
Ultra-low-noise barometric pressure sensors target smart home appliance apps
TDK Corporation announces that the InvenSense ICP-20100, the latest generation of the SmartPressure MEMS Barometric Pressure Sensors, is now in mass production and has been certified by NextNav. Launched in 2021, the NextNav Certified process independently verifies the InvenSense sensor accuracy measurements, by engaging directly with component manufacturers to rigorously test sensors in real-world operating […]
