How does ACS712 current sensor work?
The ACS712 is a fully integrated, hall effect-based linear current sensor with 2.1kVRMS voltage isolation and a integrated low-resistance current conductor. Technical terms aside, it’s simply put forth as a current sensor that uses its conductor to calculate and measure the amount of current applied.
Can ACS712 measure DC current?
ACS712 is a Hall Effect-Based Linear Current Sensor it can measure both DC(Direct Current) and AC(Alternating Current). The sensor chip is made by Allegro www.allegromicro.com.
What is the supply voltage of ACS712?
The ACS712 is a 5V device, and must be connected to the VU pin on the MBED. The 5 amp version of the ACS712 has an output range of 1.5-3.4 volts….Usage.

What is sensitivity of current sensor?
Expanding its portfolio of current sensing devices based on cutting-edge implementation of Hall effect technology, Melexis has announced the MLX91210 family.
What is the purpose of current sensor?
A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output.
Is ammeter a sensor?
A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control.
What is the use of current sensor?
Current sensors, also commonly referred to as current transformers or CTs, are devices that measure the current running through a wire by using the magnetic field to detect the current and generate a proportional output. They are used with both AC and DC current.
Can current sensor?
Reach Technologies’ CAN Current Sensors sense and digitize conductor current for collection via CAN. The module is ideal for conveniently adding current data to a distributed CAN network. The CAN Current Sensor is configurable via J1939 or CANopen stacks, and are available in Hall Effect and shunt variants.
What does a current sensor do?
What is Hall effect principle?
Principle of Hall Effect. The principle of Hall Effect states that when a current-carrying conductor or a semiconductor is introduced to a perpendicular magnetic field, a voltage can be measured at the right angle to the current path. This effect of obtaining a measurable voltage is known as the Hall Effect.
What is the purpose of the acs712 current sensor?
ACS712 Current Sensor is the sensor that can be used to measure and calculate the amount of current applied to the conductor without affecting the performance of the system. ACS712 Current Sensor is a fully integrated, Hall-effect based linear sensor IC.
Which is the ground pin on an acs712?
ACS712 has a nearly zero magnetic hysteresis. Where Pin-1 to Pin-4 forms the conduction path, Pin-5 is the signal ground pin. Pin-6 is the FILTER pin that is used by an external capacitor to set the bandwidth. Pin-7 is the analog output pin. Pin-8 is the power supply pin.
What kind of isolation is needed for acs712?
ACS712 can be used in applications requiring electrical isolation as the terminals of the conduction path are electrically isolated from the IC leads. Thus, this IC doesn’t require any other isolation techniques. This IC requires a supply voltage of 5V. Its output voltage is proportional to AC or DC current.
