EXTREMELY SMALL POWER-SAVING 3D MAGNETIC SENSOR OPENS UP NEW DESIGN OPTIONS

Infineon Technologies AG will expand its XENSIV™ 3D magnetic sensor family TLx493D. At its in-house digital trade show “Virtual Sensor Experience”, the chipmaker will present a new device for industrial and consumer applications: the TLI493D-W2BW. It uses the latest 3D Hall generation from Infineon and is housed in an extremely small wafer-level package. With an 87 percent smaller footprint and […]

Measure small currents without adding resistive insertion loss

Electronics News Updates / By Ibrar Ayyub

In most cases, you measure current by converting it into a proportional voltage and then measuring the voltage. Figure 1 shows two typical methods of making the conversion. In one method, you insert a probing resistor, RP, in series with the current path and use differential amplifier IC1 to measure the resulting voltage drop (Figure

Simple and small temperature fan controll

Electronics News Updates / By Ibrar Ayyub

I published this schematic long ago in this article: Adjustable power supply and since then I made some improvements in PCB to make the board as small as possible. The idea is to be easy to attach the whole board to the heat sink which we want to monitor. The board is only 27mm x

Small Arduino DMX controller

Sensor – Transducer – Detector Projects / By Ibrar Ayyub

In this post we show you how to make a small and useful Arduino DMX512 controller, which can use by example to handle a smoke machine with DMX, or as test equipment, etc… We can use Arduino Mega, Arduino UNO, and other with small changes. Only a handful of inexpensive components are used. In the

TOG: The Ultra-Small Bluetooth and capacitive enabled Button

Electronics News Updates / By Ibrar Ayyub

The Tog base module contains a densely packed PCB assembly, battery, and modular expansion bus in a ultra-small plastic enclosure. The base module can operate standalone with no additional components required. The front of the Tog enclosure is transparent to allow the internal LED to be visible and allow the optical sensor to detect button
