Features:
he PWM driver board uses the I2C method, so only four lines can be connected to the Arduino device: āClassicā Arduino pin mode: + 5v -> VCC GND -> GND Analog 4 -> SDA Analog 5 -> SCL Old Mega pin way: + 5v -> VCC GND -> GND Digital 20 -> SDA Digital 21 -> SCL
Designed to be easily used with micro controllers like the Arduino. These sensors are based on the Allegro ACS712ELC chip. These current sensors are offered with full scale values of 5A, 20A and 30A.
1, On-board precision micro-current transformer 2, On-board high-precision op-amp circuit, to do accurate sampling and appropriate compensation and other functions to signal 3, The module can measure AC current within 5A, corresponding output analog can be adjusted 4, Under ideal conditions, the input voltage VCC is 3-35V, according to the potentiometer (adjust the amplification ratio, amplification range 0-100 times) to adjust the required output voltage, but the output (OUT) of the maximum voltage does not exceed 1 / 2 VCC. 5, The output signal is the AC voltage signal, and the output signal voltage does not exceed the maximum 1 / 2VCC. 6, PCB board size: 38 (mm) x 18.5 (mm)
