The use of shunts for measuring current is a simpler and more cost-effective alternative to the use of sensors for current measurement. However, they are precision measuring devices, and a few things need to be considered to achieve measurements of the necessary precision.
Without sensors, there can be no Internet of Things (IoT). The fact that they require power is often overlooked. Not much, mind you – but they cannot work without it. The latest switching regulators allow sensors to be powered for much longer using batteries. Even from a 4–20mA current loop, it is possible to produce three times as much power.
An ever-increasing number of safety and comfort features in automotive applications are equipped with an electric actuator. This has also led to a rise in the number of low-power motors. A highly integrated motor controller IC from Micronas for all of these automotive motors is now available.
Bluetooth technology plays a major role in the Internet of Things (IoT) – with 8.2 billion Bluetooth-equipped smartphones, Bluetooth headsets and other Bluetooth devices already in use today. With Bluetooth 5, this is set to grow massively.
Space is at a premium on the boards of most end devices, and so plug connectors also need to shrink. An overview of mini plug connectors with additional features.
