G7-H2 Wireless Temperature Humidity Sensor System With G7 temperature humidity wireless sensor and Base Station, you can start monitoring your premises environmental condition online. Wireless sensor G7 transmits measurement to Base Station via wireless signal. Base Station collects all the wireless sensors readings and uploads to central server in interval via Modbus protocol. G7-Centre App receives data from Base Station over Internet or LAN. G7 Client App for Windows10, iOS, Android displays and stores all the incoming data in computer/tablet/smartphone for data analysis. By monitoring and understanding how environmental changes, you can adjust your air conditioner or heater to save energy and money.
