Hollow core fiber (HCF) optical sensors are used in applications including Li-ion battery research and development (R&D), robotic arms, civil engineering infrastructural health monitoring, and biosensing. Some of the attributes of HCF optical sensors are small footprints, non-conductance, chemical stability, and high dynamic ranges. In the case of activities like Li-ion R&D, HCFs can be […]

How can you detect LEL?
For combustible gases, the Lower Explosive Limit (LEL) or Lower Flammable Limit (LFL) is the minimum concentration of vapor in air below which the propagation of the flame does not occur when it contacts an ignition source, such as a spark or flame. In a specific area or space, if the LEL of a gas […]
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 current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options such as magnetoresistance and even diamond quantum sensors. One of the major issues in today’s electric vehicles (EVs) is the ongoing evolution of technology with the standards evolving as well. In the 100+ years […]
Tiny, all-in-one direct Time-of-Flight module targeted at advanced imaging applications
STMicroelectronics announced an all-in-one, direct Time-of-Flight (dToF) 3D LiDAR (Light Detection And Ranging) module with market-leading 2.3k resolution. They revealed an early design win for the world’s smallest 500k-pixel indirect Time-of-Flight (iToF) sensor. The VL53L9, announced is a new direct ToF 3D LiDAR device with a resolution of up to 2.3k zones. Integrating a dual […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and sources of new critical raw materials. One of […]
How can awareness of the need for CO sensors be increased?
Public outcries for reducing carbon dioxide (CO2) emissions to reduce their climate change impact have been widely promoted for more than two decades. However, attention to a more immediate public health problem from carbon monoxide (CO) has not received anywhere near the same level of attention– unless the deaths get news coverage. For example, in […]
Laser diffuse sensor integrates time-of-flight technology
Small housing, big operating range: thanks to TOF technology, the new ODT3CL1-2M compact diffuse sensor from Leuze achieves an operating range of up to two meters. The 2-in-1 sensor detects the presence of objects and at the same time transmits measurement values. With the new ODT3CL1-2M laser diffuse sensor, the Sensor People from Leuze are […]
What are the seven types of quantum sensors?
The seven types of quantum sensors include chemical sensors, clocks, gravimeters, imaging, interferometers, magnetometers, and thermometers. Several types of quantum sensors are already in use, and more are being developed for commercialization. They can be used in a wide variety of applications from earth sciences to molecular biology and wide band gap power semiconductors. Chemical […]
