STMicroelectronics Introduces Innovative Infrared Sensor to Improve Presence and Movement Detection in Building Automation
【Lansheng Technology Information】On July 31, 2023, STMicroelectronics released a new human presence and movement detection chip, which can improve the performance of security monitoring systems, home automation equipment and Internet of Things devices that traditionally use passive infrared (PIR) sensing technology. Monitor performance.
Traditional PIR sensors can only produce a measurable response signal when the detected object moves. The STHS34PF80 sensor has a built-in thermal transistor, so it can detect stationary objects. In addition, PIR sensors need Fresnel lenses to sense moving objects, while STMicroelectronics' new detector uses a simpler lensless structure.
Simone Ferri, General Manager of STMicroelectronics' AMS MEMS Sub-Product Division, said: "Today's smart homes, smart buildings and the Internet of Things require accurate presence detection functions to improve the control capabilities of lighting, heating, security, security monitoring and other systems, creating A sustainable future. ST's new STHS34PF80 is an affordable, ultra-low-power sensor that ensures consistent, uninterrupted operation of building automation systems, regardless of whether a detected person is moving within the building. In addition, this new product innovatively integrates CMOS chip manufacturing process, silicon micromachining technology and low-voltage circuit design capabilities."
The STHS34PF80 embeds intelligent algorithms for human presence and movement detection, targeting applications such as alarm security systems, home automation, smart lighting, IoT devices, smart lockers, and smart video intercom systems. The four-meter detection distance without lens and the 80° field of view can cover most of the area in front of the sensor. The working current is 10µA, the power consumption is lower than that of traditional PIR, and it is packaged in 3.2mm x 4.2mm x 1.455mm. It has a compact structure and is suitable for high-speed assembly in automated production lines. The sensor is highly resistant to direct light interference and electromagnetic interference (EMI).
The sensor evaluation board STEVAL-MKI231KA provided by ST can help users simplify the test development process of STHS34PF80. Developers simply plug the daughterboard into an X-NUCLEO-IKS01A3 or STEVAL-MKI109V3 mainboard to configure the infrared sensor using STMicroelectronics' Unico-GUI graphical interface software to begin a simplified measurement process . Drivers for the STHS34PF80 can be found on GitHub. Additionally, there is a ready-made software library in the X-CUBE-MEMS1 software package for compensation, detection of human or object presence. Users can quickly run simple applications first, measure with STHS34PF80, test the results, and then start creating a new application.
