Tactical grade gyroscopes typically use fiber optic technology (a fiber optic gyro or FOG) to produce a higher performance level than an industrial grade product. With its ADIS16136 tactical grade iSensor® digital MEMS gyroscope, Analog Devices, Inc. (ADI) provides 3.5°/hr typical bias stability and ±450°/Sec angular precision. This tactical level performance comes in a matchbox-sized […]

Battery Sensor IC Boasts New Features
Vehicle electrification efforts such as start/stop systems put addition strain on the battery. To keep the battery in optimal condition, system designers need to measure and monitor the battery’s state of health (SOH), state of charge (SOC) or state of function (SOF). ZMD AG’s ZSSC1856 Intelligent Battery Sensor IC performs these functions and more. The […]
Dissolved Oxygen (DO) Sensors for Continuous Submerged Water Applications
Wastewater treatment processes that use aerobic bacteria to break down organic compounds in sewage and aquaculture operations require measuring dissolved oxygen (DO) to maintain effect ecosystems. For these and other applications that need to measure DO, Sensorex developed its DO6400 and DO6441 Process Dissolved Oxygen Sensors. Both sensors use galvanic cell technology and a large […]
MEMS IMU Delivers 10-Degree-of-Freedom Capability
Today, there are several sources for six degrees of freedom (DoF) sensors. However, when 6DoF is not enough, the newest solution from Analog Devices, Inc. (ADI) may be the answer. The ADIS16488 is a 10-DoF sensor that integrates a tri-axis gyroscope, tri-axis accelerometer, tri-axis magnetometer and a pressure sensor into a single package. Based on […]
Vampires vs. Zombies Who will be the Deadliest?
For centuries there existed two iconic enemies on a ghoulish and archaic battlefield: the vampire and the zombie. And as sheer happenstance would have it, the two would oppose forces once again on none other than Spike TV’s Deadliest Warrior. With battle merits in agility, endurance, and overall combative tactics, the two archenemies wait on […]
Sensing Three Axes of Linear and Angular Motion in a 20-mm Footprint
There seems to be an insatiable demand to sense motion in the latest portable electronic products. For those with limited space, STMicroelectronics LSM330DL Micro-Electro-Mechanical Systems (MEMS) sensor could satisfy their requirements. In its 4 x 5 x 1mm plastic land grid array (LGA) package, the 6 degrees-of-freedom (6DoF) inertial MEMS module is almost twice as […]
A Gyroscope Design for Automotive Electronic Stability Control Systems
Three-Axis Digital Gyroscope Targets Consumer and Portable Applications
Today’s advancements in Micro-Electro-Mechanical Systems (MEMS) sensor technology can mean new levels of performance and reliability in specific applications. An example is STMicroelectronics newest 3-axis digital gyroscope that provides high sensing resolution with high immunity to audio noise and vibrations. Housed in a 4x4x1 mm package, the L3GD20 is immune to both mechanical vibrations coupled […]
Measure Relative Humidity and Temperature Without Wires
Wireless is the must-have attribute for many of today’s consumer and industrial products. When you get two for one, so much the better. With Omega’s UWRH-2 wireless relative humidity transmitter users get both relative humidity and temperature measurements. The battery-powered unit transmits these readings as well as signal strength and battery status back to a […]
Vent Technology Helps Oxygen Sensor Eliminate False Alarms
False alarms and premature device failures are issues for some sensors but if the application is detecting safe oxygen levels, the situation is even worse. To address those problems, City Technology developed the 4OXV, an oxygen sensor that incorporates unique vented technology. Mechanically and electrically compatible with previous generations of City Technology’s 4OX family, the […]
