# ESP32-SolarPowerMonitor
|
||||
|
||||
# To be finished when the remaining parts arrive
|
||||
|
||||
My take on a power measurement device using a ESP32, ACS712 Current Sensor & AC Voltage meter
|
||||
|
||||
## Hardware requiered
|
||||
- ESP32 dev board
|
||||
- ACS712 Current Sensor
|
||||
- AC Voltage meter for arduino
|
||||
- InfluxDB server
|
||||
|
||||
### Libraries used
|
||||
- [openenergymonitor/EmonLib](https://github.com/openenergymonitor/EmonLib) - for sensor measuring
|
||||
- [hwwong/ESP_influxdb](https://github.com/hwwong/ESP_influxdb) - for influxdb connection
