Automatic Weather Station Based On GPRS network
In recent years, weather monitoring has become
increasingly automated. An unmanned weather observation station is normally
equipped with an automated weather system consisting of the following major
components:
- A suite of
meteorological sensors housed in instrument shields and connected to a
field processing unit (data-logger) by means of shielded cables
- A field-processing
unit (data-logger) of data acquisition, processing, storage and data
transmission;
- Peripheral equipment such as stabilized power supply, Four-Faith GPRS IP modem F2103, built-in-diagnostics and local terminals for manual entry, data editing and display.
The AWS measures precipitation (amount of rainfall),
atmospheric pressure, temperature, humidity, wind speed and direction and
global solar radiation, updating the data every minutes, 24 hours a day without
human intervention.

Cellular IP Modem
Overview
The Cellular IP Modem provide secure, high speed,
reliable wireless internet connection for customers, which are all embedded
real time operating system, and integrated with common protocols, such as
TCP/IP/UDP, etc. It is quite convenient for you trigger IP
Modem to be online by audio, SMS and data. In addition, they all support
double or several data centers for data collection.
All devices are ideal for applications, such as PLC based
automation, Automatic Meter Reading, Power/water supply/street light remote
monitoring and control, weather data acquisition, environmental protection,
information display board, flood alarm, hydrological analysis, etc.
