Hello everyone,
I'm working on a project in order to read informations about my electrical consumption. I'm using Arduino+Raspberry and have an electrical meter : LeGrand 0046 81 (see 412080 Compteur modulaire monophasé EMDX³ non MID raccordement direct 63A - 2 modules - avec sortie à impulsions - Espace Pro | Legrand ).
I don't want to read the pulses but the blinking of the DEL on it. In fact, there is 1 Pulse for 10Wh whereas the DEL is blinking for each Wh consumpted (better accuray).
Do you know any light sensor that would be able to detect the blink of a DEL ?
I used some sensors but only for ambiant light, and i doubt about their ability to be able to detect a such sensitive light.
For exemple :
Photo-résistance (photocell/photoresistor/Light Dependent Resistor/LDR/CdS) @ Arduino @ t-o-f
DFRobot Ambient Light Sensor @ Arduino @ t-o-f

are the one i spoted...
What do you think ? Have you faced this situation before ?
Waiting for answers,
Thank you very much,
Regards,
