Arduinos new Nano board family is more powerful and affordable

Arduino’s new Nano board family is more powerful and affordable

Arduino’s Nano line will soon welcome four new products. They’re all small boards like the classic one, making Nano a family of small boards meant for compact projects. All the new boards boast low energy consumption and processors more powerful than what the classic has. Even better, they’re all pretty affordable: the most basic entry called Nano Every, […]

Tyre pressure monitoring system using Bluetooth Low Energy

Tyre pressure monitoring system using Bluetooth Low Energy

Author: Maurizio Di Paolo Emilio A tyre pressure monitoring system (TPMS) aims to monitor air pressure on various automotive systems. The most common TPMS sensors mainly use sub-GHz radio standards to transfer information to the vehicle’s computer. There are two different types: direct (dTPMS) and indirect (iTPMS). The use of bluetooth low energy (BLE) connectivity

THIS FORCE CONTROLLED ROBOT GRIPPER IS LESS LIKELY TO BREAK STUFF

While robotic arms can handle a wide variety of tasks, the specific job at hand will have a major influence on the type of end effector used. For sorting ferromagnetic parts an electromagnet might be enough, while for more accurate location a mechanical gripper could be employed. If you’re working with particularly delicate objects or

Air pressure sensors in smartphones

Air pressure sensors in smartphones

Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure. These sensors are currently being integrated into premium-grade smartphones, but are also becoming more common in mainstream phones or wearables such as fitness trackers and Internet of Things

Circuit provides cold junction compensation

Circuit provides cold-junction compensation

The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a thermocouple measurement, two wires of dissimilar metal join together at the “hot,” or measurement, junction. The isothermal termination of the thermocouple wires
