While the fires were still spreading in Los Angeles, investigators were busy exploring possible reasons for the fires and looking for indicators that could have provided more advanced warnings. Sensors always play an essential role in any advanced or real-time warning system. The more obvious sensor requirements/possibilities for wildfires include: Wind direction and speed Water […]

What is a balometer and what does it do?
To ensure and verify the efficient airflow in the ducts and the optimum distribution (balance) of airflow in a heating, ventilation, and air conditioning (HVAC) system, a technician would use a balometer – a type of airflow meter. This tool/instrument measures several airflow parameters from diffusers and grilles. With this data, the HVAC technician can […]
What sensors indicate the weather: part 2
With extreme weather conditions, people directly impacted by the pending situation need to know how severe it will be. For hurricanes, the Saffir-Simpson Hurricane Wind Scale provides a rating from 1 (very dangerous winds that will produce some damage) to 5 (catastrophic damage will occur) based on a hurricane’s maximum sustained wind speed. This approach […]
What sensors indicate the weather: part 1
Temperature, barometric pressure, humidity, wind speed and direction, and possible rainfall (or snowfall) in specific areas are common indicators of current and future weather conditions. However, other sensor inputs, such as pressure drop, air quality, particulate matter (including dust), and more (storm surge), are frequently required to identify and react to extreme weather conditions. The recent hurricanes […]
Does TPMS need a pressure sensor?
It seems obvious that a Tire Pressure Monitoring System (TPMS), required by several governments, would need a pressure sensor. But that’s not true. Alternative approaches take advantage of other sensing capabilities in a vehicle, computing, and algorithms to implement a solution for TPMS that meets legislated requirements. The alternative, indirect, approach has been used for […]
Pressure sensors offers digital SENT output for automotive applications
Melexis expands its Triphibian family with the MLX90834 pressure sensor, designed for automotive applications such as EV thermal management. This robust, factory-calibrated MEMS solution accurately measures pressure in both gas and liquid media from 2 to 70 bar. Its digital SENT output delivers absolute pressure information, and diagnostic and temperature data, enabling enhanced system performance […]
Pressure regulator maximizes hydrogen-powered vehicles fuel efficiency
Emerson has launched the TESCOMTM HV-7000 Series two-stage pressure-reducing regulator, which is designed to maximize fuel efficiency and improve reliability in hydrogen-powered vehicles. Easy to install, HV-7000 Series regulators provide stable pressure delivery, high reliability, and long service life for heavy-duty vehicles powered by fuel cells or hydrogen combustion engines. The HV-7000 features two-stage pressure […]
Addressing demand for advanced data acquisition for precise condition monitoring
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 […]
