I’ve been trying to figure out what is going on with this sensor(s).
I have bought a ASC758 Uni-Directional Sensor, This one:
I have wired it to my Arduino and when I start reading I get ‘120’ and I guess that’s normal given that the Uni-Directional specs state that on 0 load, the sensor will output 0.6v, and sure thing, I checked with my multi meter and I am getting 0.6v.
Problem lies when I put a load, The values will bounce in a wave fashion.
In the attached Screenshot i have enumerated the pattern
1: Right when I turn ON a hair dryer I have as load.
2: You can see the values go up as expected and reach a peak of 175
3: Value start decreasing?? back to Low of 66
4: Values start going back up again
I guess this is only happening on the Uni-Directional sensor?
Has any one used a Uni-directional ASC758?
I know I must be doing something wrong, but Can’t find out what.
Note The output i’m logging is just raw from the analogRead function.
