From the project
Optical-Probe for reading out power meters supporting IEC 62056-21 via USB
Optical probe for reading out power meters supporting the IEC 62056-21 standard via USB.
Infrared part is based on https://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf-ttl-ausgang.
For the case a ring magnet with Ø 26,75/16 mm and 5 mm height is required, e.g. this one.
PCBs can be ordered fully-assembled (besides the IR-LED and Photodiode) from JLCPCB. Required files are IEC-62056-21-Optical-Probecpljlc.csv, IEC-62056-21-Optical-Probebomjlc.csv and IEC-62056-21-Optical-Probe.zip.
