5A Hall Current Sensor Module for Arduino Projects

Great for motor controller and power supply projects

The ACS712 is a Fully Integrated, Hall Effect-Based Linear AC/DC Current Sensor with with a 5A rating. Typical applications include motor control, load detection and management, switch-mode power supplies, and over current protection Arduino projects.

Features :

• Low-noise analog signal path.
• 5µs output rise time in response to step input current.
• 50 kHz bandwidth.
• Total output error 1.5% at TA= 25°C, and 4% at –40°C to 85°C.
• Small footprint, low-profile SOIC8 package.
• 1.2 mΩ internal conductor resistance.
• 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
• 5.0 V, single supply operation.
• 66 to 185 mV/A output sensitivity.
• Output voltage proportional to AC or DC currents.
• Factory-trimmed for accuracy.
• Extremely stable output offset voltage.
• Nearly zero magnetic hysteresis.
