+# 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
