Lidar Sensor

Velodyne LiDAR (Morgan Hill, CA) has announced the Puck Hi-Res™ sensor. Expanding on the company’s VLP-16 Puck, a 16-channel, real-time 3D lidar sensor, Puck Hi-Res provides greater resolution in the captured 3D image. Puck Hi-Res retains the VLP- 16 Puck’s 360° horizontal field-of-view (FoV) and 100-meter range, but offers a 20° vertical field of view for a tighter channel distribution — 1.33° between channels instead of 2.00°. The real-time LiDAR sensor supports autonomous-vehicle, 3D-mapping, and surveillance industries and applications.

Pressure Sensor

SignalFire Wireless Telemetry (Hudson, MA) has introduced the Pressure Scout, a wireless pressure sensor that supports pressure monitoring and alarm reporting as part of the SignalFire Remote Sensing System. The first in a line of wireless integrated sensors, the Pressure Scout consists of a pressure sensor (integrated with a wireless node) and internal battery. Ideal applications for the device include well tubing and casing pressure monitoring, tank level monitoring, and compressor station status monitoring.

Magnetic Sensors

Wireless, non-contact magnetic sensors from Steute Industrial Controls (Ridgefield, CT), in the presence of their actuating magnet, send a unique, coded telegram to one or more compatible, easily-programmed receivers. The receiver accepts up to 10 discrete telegrams per channel. The magnetic devices, powered by a field-replaceable lithium battery, operate at 915 MHz (USA/Canada/Australia) or 868 MHz (Europe). Other features include sensing range of up to 30 mm; bidirectional communications with receiver; IP67 ingress protection rating; operating temperature range of -20 to + 65 °C; and a stainless-steel or glass-fiber reinforced plastic housing.

Pressure Sensors

All Sensors Corporation (Morgan Hill, CA) now offers the DLHR pressure sensor series. The new devices feature lower pressure ranges of 0.5 to 60 in H2O. All error compensation is performed internally by an advanced ASIC; no external calculation is required. The DLHR products include I2C or SPI output interfaces with 16/17/18-bit resolution. With the ability to operate at a low, variable supply voltage (from 1.68V to 3.6V), the DLHR Series supports portable applications, including medical devices associated with low pressure, remote sensing, spirometry, and industrial controls. Devices are available in 0.5, 1, 2, 5, 10, 20, 30, and 60 in H2O pressure.

Humidity Sensor

The Humidity Sensor from Develco Products (Aarhus, Denmark) allows end-users to track indoor climate. Regular readings can be sent from the sensor to an app. Users control the humidity level and temperature from a distance; several households or institutions can be monitored from one central point. Equipped with the wireless technology ZigBee, Develco’s new sensor is easily connected with other existing devices in “smart home” applications. A ventilation system, thermostat, or air-conditioner can automatically be activated by the humidity sensor.

Learning the "Keys" of IoT Security

Network-connected devices provide many opportunities to improve and enrich people’s lives, but the “Internet of Things” has a range of definitions. A consumer’s experience with the “IoT” may be a wearable computer for fitness tracking. A physician may place a connected heartbeat monitor on a patient. An industrial engineer may see the Internet of Things as thousands of sensor points that provide measurements of temperatures, pressures, or valve states.

CryoFOSS Optical Sensor Offers Next-Level Liquid Measurement

NASA engineer Allen Parker and a team at Armstrong Flight Research Center have developed a fiber-optic-based sensing technology that accurately pinpoints and measures liquid levels. The CryoFOSS, or Cryogenic Fiber Optic Sensing System, uses fiber optic Bragg sensors, located along a single cable, to actively discern between liquid and gas states. The technology can be employed in a variety of applications, from NASA’s rockets to a winery’s storage tanks.
