Sensors Expo 2017
Sensor Expo 2017 was bigger than ever. Ori Inbar, co-founder and CEO of AugmentedReality.org, gave the keynote entitled Superpowers to Change the World: How Augmented Reality Helps Advance Humanity. While augmented-reality (AR) products were sparse at the show, sensors targeting AR systems were plentiful.
Dexter Research Gas Sensor
Dexter Research was highlighting its infrared gas detectors. They deliver superior sensitivity and reliability for monitoring atmospheres for gases at trace levels. Its sensors are very rugged as they meet MIL-STD-883H standards. They can handle 1,000 g mechanical shock and 30 g in random vibration.
POZYX Delivers Ultra-Wideband Positioning System
POZYX was demonstrating its ultra-wideband (UWB) positioning system, which is accurate within 10 cm (see “Play Ball with IoT Indoor Positioning Sensors”) Comparably, Wi-Fi and other wireless technologies are on the order of 1 to 5 m, and GPS runs between 6 and 10 m. The system can also be used indoors. The Roomba demo had four sensors in close proximity, but they’re normally spaced much wider. The Arduino shield also incorporates a 9-axis motion sensor.
Murata Shows Off Flexible Temperature-Sensor Film
Murata’s flexible temperature-sensor film can be customized for temperature mapping. It will find homes in medical applications such as monitoring blood circulation, tissue activity, disease recognition, and body core temperature.
ETA Compute’s Solar-Powered Module
ETA Compute’s solar-powered module runs the firm’s 32-bit ARM Cortex microcontroller that uses deep subthreshold technology, which consumes a fraction of the power of conventional microcontrollers (see “Handling an Ultra-Low-Power Cortex-M4”). This particular processor is so efficient it can run directly off the tiny solar panel without needing a special power-scavenging management system.
DD Scientific Delivers Gas Sensors
DD Scientific was showing off its array of gas sensors. They have versions to detect a range of gases, including ammonia, hydrogen sulfide, oxygen, nitrogen, chlorine, ethylene oxide, nitric oxide, as well as combustible gases. The analog sensor hooks into analog to digital converters (ADCs).
AMS Simblee Makes Sensing Easy
AMS was showing off its Simblee sensor module system. This particular demo combines a number of sensors, including a time-of-flight range sensor (see “Time-Of-Flight 3D Coming To A Device Near You”). It turns on the fan after a certain number of people pass in front of the sensors. The module system highlights the range of sensors from AMS, which includes everything from light, flow sensing, and imaging to a magnetic position sensor.
LeddarTech LiDAR for Drones
LeddarTech is known for its LiDAR technology, which is often found on self-driving cars. This particular low-power linear system is used with drones to detect the flying height of the aircraft. The sensor is mounted on the underbody of the drone.
Microsemi Does Sub-GHz Wireless
This sub-gigahertz wireless module is designed for low-power operation while delivering data rates up to 186 kb/s. The transceiver is available in a 2- by 3-mm CSP package and has a sleep current requirement of only 10 nA. Typical applications use a coin-cell battery for long life applications.
Canon Shows Off 120-Mpixel Camera Module
Canon is well known for its film, and now for digital consumer and professional cameras. However, it’s also an OEM for the image sensor, including these ultra-high-resolution, 120-Mpixel CMOS image sensors. The ultra-sensitive sensors can capture 60 frames/s with only 0.3 lux of illumination.
PNI Embeds Parking Sensor
PNI Sensor supplies a wide range of sensors, including this parking PlacePod IoT sensor designed to be embedded in the street. It uses a highly accurate magnetic sensing system and LoRaWAN (see “LoRa Rolls Into Philly”) for wireless connectivity. The system, contained in a compact, rugged polycarbonate housing, is designed for long-term operation.
Teledyne e2v Shows Smallest Global Shutter CMOS Sensor
Teledyne e2v has a long list of image sensors. Its latest (center) is the world’s smallest global shutter (2.8 by 2.8 µm) CMOS sensor. Available in resolutions up to 16 Mpixels, it’s designed to operate with high-speed interfaces like USB 3.x and 10-Gb/s Ethernet.
Parker-Hannifin Supports IoT Sensor Family
Parker-Hannifin has a wide range of motion and control systems, including these wireless Scout SensoNode sensor nodes. The blue version supports Bluetooth. The SensoNode interface provides access to pressure, temperature, and humidity sensors. The Scout support delivers cloud-based IoT connectivity and management.
Seek Demos Thermal-Imaging Module
Seek Thermal was showing its OEM thermal-imaging module. Seek Thermal also sells a range of end-user thermal-imaging solutions, including those that work with smartphones as well as standalone devices. The module and support software demonstrated at the show allow designers to incorporate thermal imaging into their product.
