The ACS712 20A Current Sensor Module measures AC or DC current up to ±20A using the Hall-effect ACS712ELC-20A chip. It is suited for motors, inverters and battery systems where current is higher, and gives an isolated analog output readable by Arduino or ESP32.
| Chip | ACS712ELC-20A (Hall effect) |
|---|---|
| Current range | ±20A (AC / DC) |
| Sensitivity | 100 mV/A |
| Zero-current output | VCC/2 (≈2.5V) |
| Supply voltage | 5V |
| Isolation | 2.1 kV RMS |
What is the operating voltage?
5V.
How do I read current?
Current (A) = (Vout − 2.5V) / 0.100.
Can I buy the ACS712 20A Current Sensor Module in Kanpur?
Yes – buy online with delivery across India, or pick it up from the iTechBuilders store, Damodar Nagar, Kanpur.
