Orbbec Femto Mega 3D depth camera review – Part 1: Unboxing, teardown, and first try

Orbbec sent us a Femto Mega 4K RGB and 3D depth and camera for review. The camera is powered by an NVIDIA Jetson Nano module, features Microsoft ToF technology, and outputs RGB, TOF, and IR data through a USB-C port or a gigabit Ethernet port. I’ll start the two-part with an unboxing, a teardown, and a quick try with the OrbbecViewer program on Ubuntu 22.04 in the first part of the review because checking out the software and SDK in more detail in the second part later on. Femto Mega depth and RGB camera unboxing I received the camera in a cardboard package showing the camera model and key features: “ORBBEC Femto Mega DEPTH+RGB CAMERA”. The package’s content is comprised of a USB-C cable to connect to the host, the camera, and a 12V/2A power adapter. The front side of the camera features the RGB camera sensor, the TOF (Time-of-Flight) […]

STMicro STHS34PF80 IR sensor for motion and presence detection aims to replace PIR sensors

STMicro STHS34PF80 is a new IR sensor designed for IoT and Smart Home devices requiring motion and/or presence detection that offers an alternative to traditional passive infrared (PIR) sensors and is mostly useful for building automation. The latest IR sensor from STMicro contains thermal transistors (MOSFETs) that can not only detect motion but also stationary objects, something that’s not feasible with conventional PIR detectors that require motion for object detection. The company further adds that PIR sensors need a Fresnel lens to sense moving objects, but the STHS34PF80 detector does not require a lens and as a result, enables much smaller designs. STHS34PF80 key features and specifications: Range up to 4 meters without lens for objects measuring 70 x 25 cm² Integrated silicon IR filter IR sensitivity – 2000 LSB/°C RMS noise – 25 LSBrms Operating wavelength – 5 µm to 20 µm Local temperature sensor accuracy – ±0.3 °C […]
