Description
PDFMany meters, including older ones, have an LED that will flash whenever energy passes through it. For example, each flash is a 1/1000th kWh. By monitoring the time between flashes it’s possible to determine the energy consumption.
Fits a Wemos D32 Pro and a collision avoidance IR detector without any tools.
