Circuit Uncle‘s ACS712 (based on Hall Effect)  Current Sensor Module (available in India) can sense up to 20A of AC or DC current flow and is available for purchase in India with fast shipping. Sensing the current flow is a fundamental requirement in a range of applications, e.g., over-current fault protection circuits, motor control, battery chargers, SMPS, watt meters, etc. Using Hall Effect the ACS712 Module uses the ACS712 IC to measure the flowing current.

Maximum 20A of current (both positive and negative direction flow) can be detected, and which could be read as a voltage via the analog port of an Arduino UNO or Arduino MEGA.
