Current Sensor Circuit Diagram. The current sensor circuit that we will build is shown below. We only connect 5 out of the 8 pins.
No one sensor is optimum for all applications. Current sensor circuit shown from the lm741 ic. So the lm741 chip is an 8 pin.
The magnetic flux produced in proportion to the primary current if induced in the magnetic circuit passes through the hall element inserted in the gap of the magnetic circuit resulting in a potential difference vh expressed by the following formula.
The screw terminals of the asc712 current sensor module board are connected in series with the motor and power supply as shown in the circuit diagram. There are a wide variety of sensors and each sensor is suitable for a specific current range and environmental condition. The current sensor circuit that we will build is shown below. Arduino uno interfacing with acs712 current sensor circuit diagram is given below.
