EasyLogGSM data logger is based on an ultra-low power microcontroller combined
with high precision analog-digital converters and real-time multitasking
operating system. This ensures flexible and reliable continuous operation with
long battery life and system reliability.

RELIABILITY

• Built-in watchdog timers and low-level intelligence ensure reliable operation which has been verified over the years.

SENSOR INTERFACE INPUTS

• Analog sensor front end offers 4 inputs with 12 bit resolution (relative humidity, wind direction...) and 4 inputs with 24 bit resolution for precision measurements (temperature, solar radiation, pressure...).
• Each of the 4 digital inputs can be user configured to measure frequency (wind speed), time period (sunshine duration) or as a counter (rain gauge).
• In addition to the serial RS-232 data port for connection to PC or 3rd party devices, this data logger features a user selectable RS232/485 port for connecting smart sensors and other intelligent devices.
• All inputs are software configurable and offer basic statistics - average, minimum, maximum and standard deviation. 16 user defined polynomes (polynomials) are used for calculation to convert raw sensor values to engineering units.

AWS POWER MANAGEMENT

• 12V Lead Acid (Pb) battery management is provided on board. Overcharge and deep discharge protection is ensured.
• Power source choices include AC/DC Power Supply, Solar or any DC source in the range of 4-20V.

MEMORY & DATA TRANSFER

• Internal memory of about 4MB and SD memory card are used for data recording and storage.
• Real time clock with 3V lithium backup battery. Time precision is achieved by time synchronization once a day over GPRS network with worldwide time zones.
• Remote data transfer is supported by software via email or FTP using integrated quad-band GSM/GPRS modem.

APPLICATION NOTE: Difference between RS485, RS422, RS232 and interference resistance

HOW TO CONNECT A PC TO THE WEATHER STATION VIA ETHERNET:

1. The RS-232 to Ethernet converter inside the weather station is configured as a Server, which is listening on Port 10001. It has a fixed IP address. IP address and port are both user configurable. (Example:192.168.0.100:10001)
2. The internal Ethernet converter starts actively listening on Port 10001 immediately after the weather station is turned on.
3. When it receives a request to connect from a DataPC via the Ethernet connection, together they create an open bi-directional data stream. (This connection can be verified by setting up a connection on 192.168.0.100:10001 in HyperTerminal on the DataPC.)
4. Weather station and DataPC are connected and sending live data. (In HyperTerminal you should see text messages is measured values.)
5. DataPC must collect the data that it receives.
6. In case of an interruption in the connection with the weather station, the connection will remain closed until it receives a request to connect from a DataPC.
