Figure 1 shows how you can connectthe sensor to the microcontroller. Youprogram the microcontroller to generatethe control signals for the sensor. Thedesign uses a 16-MHz clock frequency.The ...

In Part 1, we covered the basics ofsensors and the characteristics youmust keep in mind when using them in designs. However, there isan enormous range of specialist sensors developed for ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

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 ...

The plug-and-play style of smart home devices is convenient but expensive. ESPHome is monumental in helping you save costs ...

Microchip is aiming at analogue sensors with a microcontroller that can measure signals while consuming less than 3µA while sleeping with one comparator monitoring an in-coming voltage. Called ...

Arduino’s brand-new Esplora microcontroller, packed with prebuilt sensors and features, could indicate a move for the DIY electronics company toward a wider segment of the microcontroller market.

There are several cheap sensors that can help you build incredibly versatile devices without spending a lot. And, you won’t ...

Most modern smartwatches have color displays, wireless capabilities, the ability to alert you to notifications, and support for running first-party and third-party apps. Sensor Watch doesn’t do any of ...
