Product Description

This is 10 channel data logger that monitor and log the voltage, current and temperature readings. The datalogger stores the log data into the onboard memory card. Datalogger uses GSM connectivity for the connection with server. All the log data is synced on the cloud server that can be viewed anywhere from the world. It is compatible with any 2G GSM network provider. The datalogger has 10 individual voltage and current channels. All channel voltage can be scanned in 3 seconds. The memory card is directly mountable (FAT32) in Windows so user can check the logs file easily using Windows machine. The log files contains the timestamp, voltage reading, current reading, temperature reading in a comma separate text file. The product has a USB port, User can access the logs using a customized windows utility. The utility is also used to set the logging interval,watch the live current and voltage readings, set the date/time nd to check other network parameters.

Working

The device has MSTB connector to connect the batteries +ve/-ve terminal. For each battery, there is provision for 1 current transformer(CT).A hall effect current transfer (CT) is used to measure the DC current flowing through the battery.The CT has to be inserted into the negative cable of the battery. When an input current flows, a magnetic field proportionate to the input current is generated in the core gap, and the magnetic field is converted to a voltage by the hall IC to obtain a value of an output voltage proportionate to the input current. The analog voltage is converted into digital value and digital values are mapped to the current scale. The hall effect CT also measure the current flow direction,that used to detect the charging and discharging cycle of the battery. Similar analog to digital method is used to read the battery voltage.

The device measure the voltage,current and temperature parameter after fix scanning interval. minimum scanning time cab be set to 3 sec. After each scan it send the data to the cloud server using HTTP protocol. Server runs a database in which all log entries are stored. If there is GSM connection problem then device store all the log data into the memory card and once the device connects with server, it transfers all the locally stored data to the database.
