- ACS712 Hall Effect Current Sensor Module 30A Range ACS712 Current Sensor1、The current sensor chips: ACS712ELC-30A;2、Pin 5V power supply, on-board power indicator;3、The module can measure the positive and negative 30 amps, corresponding to the analog output 66mV / A;4、No test current through the output voltage is VCC / 2;5、PCB board size: 31 (mm) x13 (mm);Note: ACS712 is based on the principle of the Hall test.3pcs DC 0-25V Voltage Tester Terminal Sensor Kit Size: 25mm×13mm/0.98"×0.51"(approx)TThis module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.For Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V). For Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.Voltage input range : DC0-25 VVoltage detection range : DC0.02445 V-25 VVoltage analog resolution : 0.00489 VOutput Interface : "+ " connected 5/3.3V, "-" connected GND, "s" connected For Arduino AD pinsDC input interface : red terminal positive with VCC, negative with GNDBy 3P connector, connect this module with the expansion of board For Arduino, not only makes it easier for you to detect voltage battery, can also use the IICLCD1602 LCD to display voltage.Package Included:3 x ACS712 30A Current Sensor Module3 x Voltage Tester Terminal Sensor
