Description
Overview
GAO Tek LoRa WAN wireless ultrasonic level sensor transmits measurement of any industrial analog sensor with 4 mA to 20 mA 0 V DC to 5 VDC signal to Base Station via wireless signal. Base Station collects all the wireless sensors readings and uploads to central server in interval via Modbus TCP protocol. G7-Centre App receives data from Base Station over Internet or LAN. G7 Client App for Windows 10, iOS, Android displays and stores all the incoming data in computer, tablet, smartphone for data analysis. By monitoring and understanding how measurement changes, user can be alerted by high or low level of sensor reading e.g. air pressure, water level, load cell or CO2.
