3G sensing device
Sensor
The 3G sensing device can integrate all different sensed datum from different sensors, with a timestamp added. The output datum from the sensors can be either an analog signal or a digital signal (RS232, RS485, I2C, Modbus, etc. )
Wireless Transmission
The sensor's data will be processed and sent to the internet server via 3G, LTE, or Wi-Fi wirelessly. A low power datum transmits procedure reduced the overall power consumption.
Battery Status
They were integrating the datum from different sensors with the battery status. When combined with photovoltaic (solar energy system), the battery charging status can also be shown on handheld devices.
Data logger
All datum from different sensors will be saved in the SD card or USB drive as the logged function.
