Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...
Designed by Ruictec in China, the TD04 is a LoRa-based low-power tracker that also features BLE and dual-band GNSS. It ...
Getting started with Arduino can feel quite overwhelming at first because you're faced with the decision of what board to buy ...
A Novel EFPI Sensor for Ultrasonic Testing of Partial-Discharge in High-Voltage Electrical Equipment
Abstract: A novel extrinsic Fabry–Perot interferometric (EFPI) ultrasonic sensor is developed that can detect ultrasonic signals of partial discharge (PD) in high-voltage electrical equipment under ...
The SHT3x family of sensors should work up to 1 MHz I2C. This library should also work for SHT30 and SHT35 but these are not tested yet. Sometimes you need to control more devices than possible with ...
