With just a few components, you can provide a translated signal from industrial and PLD sensors that connects safely to a microcontroller, with the added bonus of supplying 7.5 mA of regulated power.

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 ...

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 ...

Direct sensor-to-microcontroller interface techniques enable the conversion of physical measurands into digital signals without dedicated analogue-to-digital converter chips or elaborate conditioning ...

Microcontrollers are surprisingly useful for Home Assistant projects ...

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 ...

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 ...

As things get smaller, we can fit more processing power into devices like robots to allow them to do more things or interact with their environment in new ways. If not, we can at least build them for ...

These steps are thenrepeated until the reading is correct at the mid and max values. Thisis usually necessary because the gain and offset interact, that is,adjusting ...
