ACS758 Hall-Effect Current Sensor Module

The ACS758 Hall-Effect Current Sensor Module (ACS758LCB-050B / ACS758LCB-100B-PFF-T) is a high-precision, linear current sensing solution designed for electronics projects, power monitoring systems, and computer applications. Leveraging contactless Hall-effect technology, this compact SMD module accurately measures both AC and DC currents bidirectionally — all without interrupting your circuit.

Key Features

Bidirectional Measurement: Measures both positive and negative current flows with high linearity and accuracy.
Wide Voltage Compatibility: Operates on 3.3V to 5V supply — ideal for Arduino, Raspberry Pi, and other microcontroller platforms.
Two Model Options: Choose from ACS758LCB-050B (±50A range) or ACS758LCB-100B (±100A range) to match your application.
Extended Operating Temperature: Rated from -60°C to +165°C for use in demanding environments.
Low Current Draw: Maximum operating current of 13.5mA keeps power consumption minimal.
Compact SMD Form Factor: Board size of 37×18mm fits neatly into tight enclosures and project boxes.
Ready to Use: Comes as a complete module — no additional components required for basic operation.

Frequently Asked Questions

Q: What is the difference between the ACS758LCB-050B and ACS758LCB-100B models?

A: The ACS758LCB-050B is designed for bidirectional current measurement up to ±50A, while the ACS758LCB-100B extends the range to ±100A. Both use the same Hall-effect sensing principle and are compatible with 3.3V–5V microcontroller systems — choose based on the maximum current level in your application.

Q: Is this current sensor module compatible with Arduino and Raspberry Pi?

A: Yes. The ACS758 module operates on 3.3V to 5V, making it directly compatible with Arduino, Raspberry Pi, ESP32, and most other popular development boards. Simply connect VCC, GND, and the analog output pin to your microcontroller to start reading current values.

Q: Does the ACS758 module measure AC and DC current?

A: Yes, the ACS758 Hall-effect current sensor supports bidirectional measurement, meaning it can accurately detect both AC and DC currents flowing in either direction through the conductor, making it highly versatile for power monitoring and motor control applications.

Q: How many modules can I order at once?

A: This listing is available in quantities of 1, 5, or 10 pieces, making it convenient for individual prototyping projects or larger batch builds and production runs.
