Eking out the greatest return from the land requires today’s farmers and ranchers to carefully manage energy consumption, water levels, and equipment operations as well as monitor hazardous conditions that could jeopardize their livestock and consumables. Global Monitoring’s Messenger Remote Monitoring Unit (RMU) addresses these requirements. The RMU provides the capability to remotely manage and […]

Monitor pH Measurements from an iPhone or iPod
Apps are cool and when they involve sensing, they are useful, too. Sensorex Model PH-1 Meter Application Accessory allows users to easily collect data from its pH sensors and display the data on an iPhone or iPod. While the app is free from the download store, the PH-1 meter accessory and pH electrodes are sold […]
Gas Analysis Sensor Prototype Kit Available
Containing two digital drive boards with integrated electronics, the Sensor Prototype Kit from Cal Sensors allows users to develop gas analysis tools and accelerate prototyping, validation and product development. In addition to the boards, the kit has emitter, detector and software. The detector technology is a PbS or PbSe single-channel detector (SCD) or multi-channel detector […]
Smoke Detector IC Boasts Programmability
Ionization smoke detectors have been around for more than 25 years. Microchip Technology’s RE46C180 ionization smoke-detector IC shows that there is always room for improvement. In addition to being the first with horn synchronization and auto alarm locate, the IC has programmable calibration and programmable feature selection. Programmable calibration reduces component counts and simplifies setting […]
Paper and Carbon Nanotubes Combined to Detect Explosive Devices
Targeting the detection of explosives, such as improvised explosive devices (IEDs), researchers at Georgia Tech Research Institute (GTRI) have developed a prototype sensor that uses carbon nanotubes (CNTs) for the sensing element. The wireless component, a resonant lightweight antenna, is printed on paper or paper-like material using standard inkjet technology. Researchers think the low-cost sensors […]
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 […]
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 […]
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 […]
Monitoring the Quality and Blending Accuracy of Fuels
If you can measure fuel density what else can you do? One thing is make a fuel density meter. That’s exactly what Integrated Sensing Systems, Inc. (ISSYS) has done. Using its microelectromechanical system (MEMS) technology, ISSYS FuelSense meter can measure the different densities of ethanol, biodiesel and gasoline and monitor their purity and mixing ratio. […]
