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.

Main features of the sensor
- It allows precise measurement of unidirectional currents in the range from 0 A to 20 A
- It offers a low current path resistance of approximately 1.2 mΩ, which results in low power losses
- Provides electrical insulation up to 2.4 kV RMS
- Generates an output voltage proportional to the input current - 200 mV / A for a supply voltage of 5 V
- It operates on a passband of 120 kHz
- It operates in a voltage range of 4.5V to 5.5V, with 5V being the preferred voltage
- Enables direct soldering of wires to the sensor or use of solderless connectors
Current sensor applications
The current sensor can be used to monitor the current values of various electrical systems , e.g. in industrial machines, robots or automation systems. Thanks to its ability to precisely measure current, it is possible to detect possible overloads or irregularities in the operation of devices, which contributes to increasing the safety of systems.
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.
