I’m trying to use my Arduino as a data logger to measure appliance power. To do this I used a CT Sensor and wired it as shown in attachment (arduino ac current input A). When I ran it and hooked the CT Sensor up to the hot wire of a Cuisinart girddler I got a sawtooth response shown in the other attachment (griddler_response).
Anyone know why it’s a sawtooth? I was expecting more of a Sine wave.
