Arduino Current Sensor This Arduino based current, voltage, and power sensor/meter tutorial was created for hacktronics by Steve Spence. For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial pr...
This examples/Grove_XXXA_Current_Sensor is just a simple display demo by the serial port monitor. When there is no load, the display is not 0 and the error is large. You need to calibrate according to the following steps. 1. The value of the sensorValue is read when there is no cu...
