Development kit enables turnkey acquisition of IoT sensor data
ON Semiconductor has announced a complete wireless battery-free sensing solution kit (SPSDEVK1) that allows the company’s innovative Smart Passive Sensors (SPS) to be rapidly integrated into Internet-of-Things (IoT) applications. The SPSDEVK1 solution kit is plug and play ready for users to immediately measure, aggregate and analyze the data for various IoT applications. SPS wireless and battery-free sensors enable the monitoring of […]
Eye and Constellation Diagrams, Pt 1
Digital signals representing data symbols may be presumed to be clean, consistent representations of ones and zeroes when they are launched onto their communications medium, whether it is a wired, wireless RF, or optical fiber link. However, due to bandwidth limitations of the medium, external and internal noise, crosstalk, multipath, reflections, and many other unavoidable […]
Analog switch vs. digital switch ICs
Analog switch integrated chips (ICs), when turned on, will conduct both analog and digital signals from the input pin to the output pin. Digital switches can only accept digital signals and duplicate the logic level on the input pin at the output pin. When the digital switch is turned off, it returns to a default […]
Optocoupler selection and usage for isolating a PWM
An optocoupler (or optoisolator) is a device that galvanically separates circuits and is not only great at isolation but allows you to interface to circuits with different ground planes or that operate at different voltage levels. Optocouplers are “fail safe” in that if subjected to voltages higher than the maximum rating, they are known to […]
High-rez 29-MP CCD image sensor targets high-end security, machine vision, and aerial surveillance
ON Semiconductor is improving performance for industrial imaging applications that require both high resolution image capture and maximum image uniformity. The new 29 megapixel KAI-29052 image sensor provides up to twice the imaging sensitivity of the existing KAI-29050 in the wavelength range of 500 nanometer (nm) to 1050 nm. This improved performance is particularly beneficial to […]

Sensors drive IIoT innovations
by Wiren Perera, ON Semiconductor The IoT has spawned the concept of the Industrial Internet of Things (IIoT). The IIoT includes the concept of greatly enhanced connectivity in areas such as industrial automation, security and surveillance and building automation. The IIoT uses sensors and actuators embedded in equipment and objects, linked via wired or wireless […]
