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 […]
STMicroelectronics’ Three MEMS Sensors Provide 10 DoF
If a single MEMS sensor is good, a system that provides 10 degrees of freedom (DoF) should be an order of magnitude better. The three ST MEMS sensors include a geo-magnetic module, a gyroscope, and a pressure sensor. With these sensors, a consumer device can provide a complete indication of its linear acceleration, angular velocity, earth […]
Digital Output DC Current Sensor Avoids Sampling and A/D Converter Circuitry
Typical current sensing techniques that use a Hall Effect sensor or a resistive shunt deliver an analog output that requires additional circuitry for use in digital control circuits. Micro Oscillator Inc. has introduced an isolated high-side DC current sensor that provides a uni-directional current sensing system with a frequency output. The pulsed output of the […]
DC Transducers for Current Applications up to 400A
The DCT series of DC current transducers combines a Hall Effect sensor and signal conditioner into a single package for use in DC current applications up to 400A. Designed to be compatible with most PLCs, data loggers and SCADA systems, the DCT series features jumper-selectable current input ranges and industry standard 4-20 mA or +/- […]
Infrared Detector Arrays Boast Enhanced Measurement Stability
For those applications that need to sense PbS and PbSe, Cal Sensors’ LMA (Linear Multiplexed Array) family of lead salt infrared detectors can provide up to 25% increased measurement stability. Consisting of six compensation elements and 250 active elements, the 256-element array provides real-time measurement compensation for environmental changes. Measurement corrections are made based on a comparison of the […]
