ACS712 20A Current Sensor

Description :

The ACS712 is a series of Hall effect-based current sensor modules that can be used to measure the current flowing through a conductor. The ACS712 module with a 20A range is one of the common variants, designed to measure currents up to 20 amperes.

Here are key features and information about the ACS712 20A range current sensor module:

Key Features :

1. Current Range : The ACS712 module with a 20A range is designed to measure currents up to 20 amperes.
2. Type of Sensor : It utilizes the Hall effect to measure the magnetic field generated by the current flowing through a nearby conductor.
3. Output Signal : The ACS712 produces an analog voltage signal proportional to the current being measured. This signal is typically centered at a voltage level of Vcc/2.
4. Voltage Supply : The module usually operates at a voltage of 5V, and the output signal is referenced to this voltage.
5. Sensitivity : The sensitivity of the ACS712 is expressed in millivolts per ampere (mV/A). For the 20A range, the sensitivity is typically around 100 mV/A.
6. Zero Current Output : The output voltage is centered at Vcc/2 when there is no current flow (zero current).
7. Application : Commonly used in applications such as current monitoring in electronic projects, motor control, power supplies, and energy monitoring where the current can be up to 20A.
