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 |
