Sensor-based automation for smart buildings
Cloud-based intelligence can help serve as a nervous system for controllers handling multiple building domains. Preet Sibia, Power and Sensor Systems, Robert Junker • Infineon The core principle of building automation is the centralized control of a building’s domain, such as HVAC, shading, lighting, access control systems and more. Real-time monitoring of usage patterns and […]
Next-gen MEMS microphone sports 73 dB SNR, high acoustic overload point
Infineon is launching a next-generation analog MEMS microphone that renders even better results – the XENSIV MEMS microphone IM73A135. In microphones, designers often have to accept trade-offs: high signal-to-noise ratio (SNR), a small package, high acoustic overload point, low power consumption, MEMS versus electret condenser microphones (ECM). For this reason, applications that require the highest […]
3D depth sensor is based on ToF technology
Gaming, virtual e-Commerce, 3D online education: Augmented Reality (AR) applications with three-dimensional depth sensors link the real with the digital world and are strongly demanded. Infineon Technologies AG and pmdtechnologies developed a 3D depth sensor based on the Time of Flight (ToF)-technology which outperforms other solutions in the market and aims for target applications that offer […]
Teardown: Cisco Explorer 8642HDC high-definition DVR with multi-stream cableCARD interface
The Covid-19 pandemic has forced many people to spend more time in front of a TV set. Here’s a look at what’s inside the cable box responsible for a large portion of home entertainment. Examine the hook-up for many cable TV customers and you’ll likely find something like the Cisco Explorer 8642HDC DVR. This set-top […]
How does sensor fusion improve an alarm system?
At Sensors Expo 2019, Tanja Hofner, a Principal Hardware Engineer for RF and Sensors in Infineon’s Power Management and Multimarket segment explains the operation of the company’s Integrated Alarm System demo. The demo uses two Infineon sensors: the digital XENSIV IM69D130 microelectromechanical systems (MEMS) microphone and a DPS310 digital barometric pressure sensor as well as […]
What’s missing from many smart homes today?
In the home of the future, many different types of sensors will allow the owner and authorized users to activate several functions remotely. To avoid unauthorized users from accessing these systems and even gaining entry into the home, security must be designed in. At Sensors Expo 2019 in San Jose, Steve Hanna from Infineon who […]
RF Switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option – and use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]
Key factors to consider when choosing a microcontroller
When designing an embedded system with an MCU, which one should you pick? This guide provides you with a quick overview to help you narrow down your choices. A microcontroller (MCU), is the smallest and most basic computer. Running on a single chip, it has a CPU, memories (RAM and ROM), and interfaces (input/output ports) […]
