The data collector is connected to the air compressor controller and uploaded to the internet platform through flow cards, WIFI, and other methods. Users can view the real-time operation status of the device, understand historical data, fault information, and remotely control the device on their mobile phones and computers. At the same time, relying on the powerful collection capability of the adapter, we can also collect data from the equipment inside the air compressor station (flow meter, frequency converter, point meter, dryer, etc.), achieving monitoring and management of the air compressor station. This app will provide IoT features related to fault warnings and parameter previews for air compressors and their supporting products
