. -", pay attention to "+" to
the positive pole of the battery (power), "-" to the negative pole of the battery
(power supply). Do not connect the positive and negative poles of the battery (power
supply) to the positive pole of the load. Connect the positive pole of the battery
(power supply) to the positive pole of the load. The negative pole of the battery
(power supply) is connected to the negative pole of the load through the Hall sensor
when flowing through the Hall sensor. When the current direction is the same as the
direction of the power-on arrow of the Hall sensor, the measured current will show a
positive value, otherwise the measured current will show a negative value.
