Electronic Specifier takes a look at the top sensor products to have been released in October.

1) Renesas expanded its sensing portfolio with thermopile-based detectors for CO2 sensors.

Four single and dual-channel analogue detectors for CO2 expand Renesas’ environmental sensor portfolio. The thermopile-based detectors have integrated optical filters for optical CO2 sensors.

They are in a TO-5 package, making them suitable for use in industrial, medical and IoT applications that require high reliability, high accuracy, and operation in high temperatures.

The detectors deliver response times with a time constant from 18 to 25ms and a signal-to-noise ratio range of 1,981 to 4,953 for mission-critical applications.


 2)Semiconductor giant Melexis and automotive software leader emotion3D have partnered to offer a driver monitoring system with high-precision 3D driver localisation, to dynamically align augmented reality (AR) objects with head-up display (HUD) content.

Melexis and emotion3D’s novel driver monitoring system (DMS) uses time-of-flight and covers all basic functions, such as driver drowsiness and attention warning to conform to the EU’s General Safety Regulation and Euro NCAP’s testing protocols. In addition, the demonstrator provides 3D locations of the driver’s facial landmarks, which are required for an optimal AR-based, head-up display for the user. The objects projected by the HUD require precise alignment with real-world objects, following the dynamic position changes of the driver.

The demonstrator consists of a camera built around Melexis’s MLX75027 3D ToF sensor and emotion3D’s advanced in-cabin analysis software (E3D ICMS). Melexis says that the software can be flexibly integrated in any automotive system on a chip.


3) The design of Laird Thermal Systems’ thermoelectric-based Nextreme NRC400 Performance Chiller provides a reliable cooling solution for digital light microscope applications.

 

This next-gen recirculating chiller achieves 400 watts of cooling capacity and a temperature control stability to within ±0.05°C under steady-state conditions to ensure high resolution images and long-life operation with zero global warming potential.

Digital light microscopes utilising a CCD or CMOS sensor-based camera, such as those used in life science and biotechnology research, require precise temperature control to maintain high-quality image resolution.

Digital microscopes contain several imaging sensors and field-programmable gate array semiconductors to enhance image quality and camera functionality. Because CCD and CMOS image resolution degrades as temperature increases, sensor temperatures of 18°C or lower may be required to allow for long exposures.


4) In stock at distributor Mouser Electronics is the ENS160 digital metal oxide multi-gas sensors from ScioSense.

These multi-gas sensors offer a 1.67V to 1.98V supply voltage range and up to +85°C temperature rating. They are based on metal oxide (MOX) technology with four MOX sensor elements.

Each sensor element has independent hotplate control to detect a wide range of gases.

The ENS160 series features TrueVOC air quality detection and supports intelligent algorithms, which calculate COequivalents, TVOC, and air quality indices (AQIs) and perform humidity and temperature compensation.

Applications for the sensors include building automation, smart home, HVAC, home appliances, and IoT devices.


 

5) onsemi has confirmed its attendance at VISION at the Landesmesse in Stuttgart, Germany, a trade fair for machine vision. Visitors to the onsemi booth will be able to see demonstrations of their latest intelligent sensing technologies and discuss imaging applications with its technical staff. 

Featured on the booth will be the onsemi XGS family of CMOS image sensors supporting multiple resolutions and frame rates, all at a 12-bit resolution. Based upon an 3.2mm global shutter pixel, the company claim that XGS devices offer high resolution with excellent image quality and uniformity. All devices within the XGS family share a common design and footprint, allowing a single camera design to support multiple resolutions without requiring further additional design effort.

Suitable for machine vision as well as other industrial, transportation, security and inspection applications, the XGS devices offer an energy efficient design in a compact package that is compatible with 29 x 29mm camera designs. Available demonstrations at the onsemi booth will include the X-Cube reference design and X-Celerator FPGA development platform, based on the XGS 5000 (5.3 MP 2592 x 2048px), XGS 16000 (16.0 MP 4000 x 4000px) and the flagship XGS 45000 (44.7 MP 8192 x 5460px) able to run at 8K video at 60fps.
