– This module can be used to test the current and voltage.
– The principle of voltage test based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.
– analog input voltages up to 5 v
– AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of the input voltage detection module is 0.00489Vx5=0.02445V.
– The MAX471 chip on the board was used to test the consumed current of the load.
– Material: Plastic
– Color: As picture show
– Size: Approx. 20x28x6mm/0.79×1.10×0.24inch
1 piece Current Sensor
Pls, allow an error of 1-3mm due to the difference of manual measurement.
