Septic systems release nitrogen and excess nitrogen causes toxic algal blooms in coastal communities. These blooms can lead to beach closures and degrade water resources. The US Environmental Protection Agency (EPA) estimates that over 2.6 million existing systems could be good candidates for advanced septic systems that treat the nitrogen due to their location in […]

What types of sensors are used in robots? Part 1 of 2
Fully functional human robots, such as those being developed by Boston Dynamics, need numerous sensors to simulate a variety of human and beyond human capabilities. For the human part, the sensors provide the ability to see, hear, touch and move. In general, industrial robots employ sensors for a variety of activities. Some sensors provide environmental […]
How does a smart home control windows, blinds & shutters?
At CES, Marketing Director Michael Rasmussen of the VELUX Group explains how a partnership between Velux A/S and Netatmo achieves the first smart roof, windows, blinds & shutters solutions using sensor technology to measure temperature humidity, CO2 and sunlight level. Velux provides the electrically operated hardware and Netatmo provides the sensing technology. The systems software […]
How can patients monitor their glucose level without drawing blood?
At CES 2017, Luc Pierat, Founder and CEO of PKvitality tells how K’Track Glucose, a watch-like fitness monitor with an added sensing module can calculate glucose without drawing blood by sampling interstitial fluid just below the skin with a chemical sensor. The Glucose K’apsul biosensor fits into the base of the device and effortlessly probes […]
Solid State Oxygen Sensors Use Optical Technology
Zirconia is commonly used for oxygen sensing. In addition to this technique, SST Sensing Ltd. has added the LuminOx family of optical oxygen sensors to its product offerings. The sensors use fluorescence quenching by oxygen where pulsed light is directed onto an oxygen-sensitive fluorescent dye causing it to fluoresce. The rate at which this fluorescence […]
Environmental Sensor Kits for Improving Indoor Air Quality
Monitoring indoor air quality (IAQ) is an essential aspect of a smart (or any) building’s heating, ventilation, and air conditioning (HVAC ) system – especially as the sealing to minimize cooling or heating leakage has improved. One recent study found that well-ventilated offices with below-average levels of indoor pollutants and carbon dioxide (CO2) resulted in […]
Tiny gas detector sits in TO39 housing
Even smaller, even stronger – this is how we might describe the new LRM-254 detector by InfraTec in just a few words. This miniaturized four channel detector in TO39 housing, with an aperture of only five millimeters, has just expanded the product range of the Dresden manufacturer, InfraTec. A mere glance at its appearance gives […]
Cloud-based Applications Support for Weight Scale and Toxic Gas Sensor Designs
At Sensors Expo 2015 in Long Beach, CA, George Clernon, tools engineering manager for Core Markets at Analog Devices, explains the company’s cloud-based reference design demos for weigh scale and toxic gas sensor applications. For more information about the weigh scale click here and for the toxic gas sensor, click here.
Home Monitoring System can See, Hear, Feel and Smell
Withings combined ams AG’s gas sensor with a 5Mpixel video camera, dual microphones, temperature and humidity sensors and Wi-Fi® and Bluetooth® Smart radios in its Home monitoring system. The result is a system that can see, hear, feel and smell and alert the home owner though a smartphone or tablet app. The AS-MLV-P2 MEMS gas […]
Give Sensor-Based Gifts This Holiday Season
I love sensing technology but that would not impress anyone on my shopping list. However, products with sensors are cool and do things that could not be done before. That makes them impressive gifts. For the golfer on your list (or yourself), the SensoGlove has built-in digital sensors that automatically tell users which finger is […]
