Parent Projects
Design requirements
- Precise, easy calibration, reduced size, Current and Voltage measuring system
- Modular communication module: XBEE (jNode?, Etherner?, CAN?)
- Load ON/OFF or dimmer (10-12A Triac)
- Integrated 220V to 9V-5V power supply (ex. 220 to USB chargers > Switched-mode power supply?)
- Optional: RTC chip for having time stamps on the measurements.
- Optional: RGB LED / LCD for feedback
Software Projects
