Product Description
This is single channel data logger developed to monitor the battery voltage deployed to power surveillance systems at big warehouses. This device continuously monitors battery voltage and gives alert in case of battery failure. It has a LCD display that shows the live battery parameters like voltage, current and temperature. Device stores all the recorded data into a memory card. The memory card is directly mountable (FAT32) in Windows so user can check the logs file easily. 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.
Working
The battery +ve/-ve terminal needs to be connected to the BAT port of the datalogger. 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 product does not need the external power supply for the working. It runs on the battery power and consume very little current so it wont drain the battery significantly. External power supply port is also provided if required. A wakeup button is used to turn ON the display and shows the voltage and current readings. After some time display gets turn OFF to save the battery power.
