Advancing Sustainable Industrial Systems with Smart Sensors: Highlights from Sensor + Test 2024
STMicroelectronics took part in the international trade fair SENSOR + TEST 2024 in Nuremberg, Germany from June 11th to 13th, 2024. The event, which drew over 5,000 attendees, highlighted the latest developments in sensor technologies. It provided a platform for STMicroelectronics to engage with customers and partners, as well as to discover potential business prospects.
At the event, we showcased our newest sensing technologies designed to enhance safety and efficiency in industrial systems. Our products focused on improvements in condition monitoring, low-power vision, intelligent perception, and current monitoring. This article will outline some of the main demonstrations that attendees had the opportunity to experience firsthand.
The ISM330BX is a flexible IMU that is suitable for monitoring conditions, robotics, and household appliances. It is specifically created for various industrial uses, including detecting anomalies in water systems and pumps. This device integrates a 3-axis digital gyroscope and accelerometer with built-in capabilities for monitoring conditions, tracking 3D orientation, and measuring vibrations.
The IMU is well-suited for monitoring conditions because of its 3-axis accelerometer that has a low-noise, wide-bandwidth frequency response of 2 kHz. This feature allows it to meet the rigorous ISO-10816 vibration severity standards. In addition to condition monitoring, the ISM330BX can also be utilized in robotics applications. It provides precise 3D orientation tracking through sensor fusion low power (SFLP) technology, allowing for accurate operation with low power consumption. Furthermore, its vibration sensing capabilities make it a great fit for robotic systems.
One of the features of this system is the ability to measure and compensate for vibrations, detect anomalies to identify faults, and detect water leaks using Qvar sensing technology. This system-in-package is included in STMicroelectronics' longevity program, ensuring availability and support for at least 10 years after the product is introduced. This is important for applications that have long development cycles or extended lifespans in the field.
The TSC2020 current sense amplifier is well-suited for applications like motor control, battery management systems, and solenoid valves. It offers high precision with minimal offset voltage (up to ±150 µV) and temperature drift (0.5 µV/°C), low gain error (maximum 0.3%) and drift (3.5 ppm/°C), and can function within a broad common-mode voltage range (from -4V to +100V) for use in high voltage systems.
The bidirectional current sensing feature provides versatility, while the high common-mode rejection of at least 100 dB reduces noise for accurate measurements. The design also includes built-in EMI filters, improved PWM rejection, a wide temperature range of -40°C to +125°C, and AEC-Q100 certification for automotive use. Additionally, users have the option of internal fixed gain settings (20V/V, 50V/V, or 100V/V) to eliminate the need for external resistors. The adaptable pin configuration allows for both bidirectional and unidirectional current sensing using only two reference voltage pins (Vref1 and Vref2). Available in SO8 and MiniSO8 packages, the TSC2020 minimizes the space required on the PCB. This amplifier is part of STMicroelectronics' extensive line of current sense amplifiers, offering a wide selection of high-performance devices.
The VD55G1 is a new type of intelligent and energy-efficient vision system. This sensor from ST, with a resolution of 0.56MP and global shutter technology, offers a compact and low-power solution for image capture. Its small pixel size of 2.16µm allows for a tiny sensor size of 2.73 x 2.16 mm², making it suitable for use in AR/VR glasses and other devices with limited space. In addition to its small size, the VD55G1 is known for its low power consumption, making it perfect for use in battery-powered devices like security cameras. The sensor also features a smart auto wake-up function, which helps to further improve efficiency by allowing the sensor to remain in a low-power sleep mode and only activate when needed, reducing constant power usage.
Additionally, the VD55G1 camera is equipped with on-chip functions such as autoexposure and noise reduction to provide superior image quality. It can remove background noise and capture frames of events with synchronized data output. The camera is easy to integrate with MIPI CSI-2 output and I²C/I3C interfaces.
STHS34PF80 is a new infrared sensor designed by STMicroelectronics for detecting occupancy in various applications. Unlike typical PIR sensors, STHS34PF80 can detect both stationary and moving objects within an 80° field of view. This is made possible by its high sensitivity (2000 LSB/°C) in the 5 µm to 20 µm wavelength range.
Furthermore, this sensor can identify when a person is nearby within a 4-meter range without the need for large Fresnel lenses. Its small LGA package size of 3.2 x 4.2 x 1.455 mm makes it easy to integrate into various devices. The sensor contains built-in algorithms for detecting movement and human presence, minimizing the need for additional microcontrollers. This feature helps the sensor consume very little power, only 10 µA at 1Hz, which is beneficial for creating environmentally friendly products.
