Product description: ACS724 current sensor 0 A to +20 A - Pololu 4044
The ACS724 module is a Pololu sensor used to measure linear current in the range from 0 A to 20 A. The current sensor uses the Hall effect , which guarantees precise measurement results and is used to monitor current in various electrical systems. It provides low current resistance up to approximately 1.2 mΩ and has electrical insulation up to 2.4 kV RMS . Additionally, the high passband value of this board allows for quick response to current changes. It operates in a wide temperature range - from -40°C to 150°C , which also makes it suitable for applications in difficult environmental conditions.

The current sensor is suitable for monitoring the current in various electrical systems.
Current sensor pins.
Current sensor pins
- IP+ (Positive Current Input) : A pin intended to be connected to the positive side of a circuit carrying current in order to monitor it.
- IP- (negative current input) : a pin intended to be connected to the negative side of a circuit through which current flows for the purpose of monitoring it.
- VCC (logic power supply) : used to connect the supply voltage for the current sensor measurement system. The supply voltage should be between 4.5 V and 5.5 V.
- OUT : output of the system from which an analog voltage proportional to the measured current is read. This signal can be further processed or used for direct current monitoring.
- GND : system ground.
