The wireless transmission part of the wireless/wired dual-mode power health monitor mainly uses the Mdbed BLE Sensors Tag Bluetooth module. Through the Bluetooth module, information such as sound, power temperature, power fan speed, noise, and odor is sent to the mobile phone. The mobile phone can also perform an emergency power cut through the Bluetooth … Read more
Commercial drones have begun to be used for detecting oil drilling towers and crops. However, they still require skilled manual operation; even semi-automated drones often need pre-made maps or data imported via wireless connections. Researchers from the Swiss Federal Institute of Technology in Zurich are creating more autonomous drones. They have demonstrated that a small … Read more
