Particulate Matter Sensor

The SPS30 particulate matter (PM) sensor represents a technological innovation in optical PM sensors. Its measurement principle is based on laser scattering and makes use of Sensirion's (Staefa ZH, Switzerland) contamination-resistance technology. This technology, together with high-quality and long-lasting components, enables accurate measurements from the device's first operation and throughout its lifetime of more than eight years. It can sense particulate matter with particle diameter down to 2.5 microns (PM2.5). These particles are among the most dangerous air pollutants. Due to their small size, PM2.5 particles can travel deep into the human lung and cause a variety of health issues; for instance, by triggering asthma attacks or contributing to cardiovascular disease. The SPS30 will enable the implementation of innovative air quality monitoring devices that prevent air pollution damage.

Wireless Pressure Gauge

Emerson Automation Solutions (Austin, TX) has introduced a WirelessHART® pressure gauge. The Rosemount Wireless Pressure Gauge enables remote collection of field data, keeping operators updated on changing field conditions and improving personnel safety by reducing manual operator rounds and field exposure.

The gauge utilizes piezoresistive sensor technology. With the flexibility to accommodate changing process conditions, it also has up to 150X overpressure protection compared to traditional gauges, which provides for a safer field environment by using two layers of process isolation.

Bourdon tube gauges have traditionally been a mainstay for pressure readings but are limited to visual indication of process conditions when an operator is present. They also use moving parts, which can break or wear over time due to use and vibration. This wireless pressure gauge, however, eliminates the common weak points and its 4.5-inch gauge face provides easy field visibility.

Multi-Turn Absolute Encoders

Sensata technologies (Swindon, UK) is introducing model MH multi-turn encoders with either Ethernet/IP or ProfiNet interfaces. They provide up to 16 bits per turn and 14 bits of turns counting. The compact packaging allows these encoders to be integrated into existing designs with a (-40 to +85C) temperature range and an IP65 rating. Included in the design is a geared turns counter that is immune to electrical or magnetic interference. In addition, they feature reverse polarity and short circuit protection as standard.

Applications include packaging, where they help to identify the position of products along the process line; in metal forming for determining the absolute position of strips, bars, rolls, or tubes that need to be marked, scored, slit, inspected, or formed. They are also often used to determine the angle of rotation and position of a crane boom, as well as the amount of cable payout.

1D Time-of-Flight Sensor

The new sensor from ams (Premstaetten, Austria) is designed for implementing presence detection, for example to trigger the operation of a facial recognition system when the user's face is in range. Supplied in a 2.2mm × 3.6mm × 1.0mm package, the TMF8701 sensor fits in a narrow bezel, helping smartphone manufacturers to realize widescreen phone designs that have a high display screen to body ratio. It integrates a VCSEL infrared emitter, multiple SPAD (single photon avalanche photodiode) light detectors, time-to-digital converter, and a histogram processing core. The device implements all histogram-based presence detection, distance measurement, and proximity sensing algorithms on-chip. It also separately identifies reflections from fingerprint smudge contaminations on the display screen and optical reflections from objects beyond the cover glass, such as the user's face, maintaining reliable performance even when the sensor's aperture is dirty.

Confocal, Compact Sensor

The new, confocal chromatic confocalDT IFS2404-2 sensor from Micro-Epsilon (Raleigh, NC) is used for high precision distance and thickness measurements of transparent materials. With a diameter of 12 mm, it can be integrated into restricted installation space. The lens enables high measurement accuracy and a small light spot diameter.

Together with the confocalDT 2421/2422 controller, the new sensor offers an excellent price/performance ratio for OEM purposes. Available as either a single- or a dual-channel version, these confocal chromatic measuring systems are an economical solution, particularly for high volume applications. They operate on a non-contact, and therefore wear-free, basis while the active exposure regulation feature in the CCD line accurately and rapidly compensates for changing surfaces. Data is output in real time via an EtherCAT interface. The thickness calibration feature enables precise thickness measurements across the entire measuring range of the sensor.

Sensor Development Kit

ON Semiconductor (Nuremberg, Germany) is introducing the RSL10 Sensor Development Kit, designed to provide engineering teams with a comprehensive platform for developing IoT applications with smart sensor technology, enabled by Bluetooth Low Energy radio.

The kit brings together the RSL10 System-in-Package (RSL10 SIP) with a range of low power sensors from Bosch Sensortec. The development platform provides 9 degrees of freedom (DoF) detection and environmental monitoring, including ambient light, volatile organic ompounds (VOC), pressure, relative humidity, and temperature. An ultra-low noise digital microphone is also included, along with a user-programmable RGB LED, three programmable push-button switches, and 64 Kbit of EEPROM. It includes Sensortec's highly integrated BME680 environmental sensor to detect a broad range of gases for air quality applications, the BMM150 geomagnetic sensor, and the BHI160 smart sensor for high accuracy motion sensing.

Tiny MEMS Pressure Sensor

The LPS22HH MEMS piezoelectric absolute pressure sensor from STMicroelectronics (Geneva, Switzerland) is so accurate and stable that manufacturers can eliminate one-point calibration (OPC) after soldering, to increase throughput and efficiency.

With a pressure noise equivalent to 5cm, the LPS22HH enhances controls such as collision avoidance for drones or other unmanned vehicles. Its high accuracy also improves features of smartphones and sport watches, such as indoor navigation. Its temperature compensation relieves the load on the host microcontroller or application processor. It has a fully molded package with miniaturized apertures that prevent particle contamination. Energy-conscious features include a 0.9μA power-down mode and low active power, drawing 4μA at 1Hz, including temperature compensation, to maximize battery runtimes. It supports I2C, SPI, and MIPI I3C, 2-wire sensor-bus interface connectivity, and has a 128-bit FIFO for storing sensor data to minimize host intervention.

BACnet™ Temperature/Humidity Sensor

The BN Series room temperature and humidity networked sensors from ACI (Middleton, WI) are a cost effective, single or dual point native BACnet™ sensing solution designed to reduce the need for additional input modules or building management controllers when a limited number of input points are available. The BTL Certification provides confidence that these sensors may be used in any new or retrofit installation using a BACnet MS/TP controller with third party BACnet devices. The reduced number of BACnet objects helps to reduce the sensor cost and simplifies installation and programming time. They're designed for measuring ambient air temperature/humidity in office buildings, schools, clean rooms, pharmaceutical labs, hospitals, data centers, and retail stores.
