Based on the ACS712ELCTR-20A-T chip of the Allegro, this current sensor is able to detect AC or DC current values between 0 and 20 A. It has 3 pins (power supply and analog output) and a 2-pole terminal to which the load will be connected as a traditional ammeter. On the output there will be a value of 100 mV for each Ampere readed and 2.5 V if the current is zero. Power supply: 5 VDC, VOUT: 100 mV / A, measuring range: from 0 to 20 A.
