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.
Contract manufacturing offers many benefits, particularly lower costs and greater flexibility. A major disadvantage is the risk of espionage and/or the copying of production data. Special programming systems help to keep control of in-house data and prevent illegal copies.
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.
