Prototype energy meter (10 bit A/D) containing a PIC micro + WiFi sending the following params.
Irms, Vrms, Power, Total Kw/h, Frequency, Temperature, Humidity.
Coming soon. Power factor, 3 channel Irms, 12 bit A/D. Accuracy +/- 2%
This is my homemade digital anemometer. It is made of cups rotating with a magnet triggering a reed switch. The wires are connected to an Arduino Uno that calculates the time between consecutive pulses (after reed switch debouncing by my arduino software)
