Capacitive sensor technology has evolved markedly over recent years, underpinned by advancements in integrated circuit design and novel measurement approaches. These sensors function by detecting ...

As with traditional mechanical switches, a user's interface experience with a capacitive sensor is directly related to the way the sensor responds (sensitivity) upon contact under all operating ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

ZMD AG has announced the high-precision, low-power, low-voltage multi-channel ZMD21013 sensor signal interface circuit. The device is the first member of ZMD‚s new MUlti-Sensor Interface Circuit ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

Inter integrated circuits (I2C) is a multi-master, low-bandwidth, short distance, serial communication protocol. Because of its simplicity and flexibility, I2C and its derivatives are widely employed ...

In winter, it’s important to ventilate living and working spaces regularly. Here’s how to make a homemade measuring station ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...
