• Power monitor system ,using STM 32 wb with the monitoring and the estimate levels.
• It also has a local ML model written in C , that predicts the consumption. Current sensor connected to pin AO -> ADC1 IN1 Voltage sensor connected to pin A1 --> ADC1 IN2

• A variac is used for transforming the input AC value to a stepped down value with quantization at 2 4 6 8 10 12.
• Output dc voltage --> tested with multimeter.

1. Stm32 nucleo
2. dht 11 for moisture levels
3. voltage sensor and current sensor
4. A custom voltage source (VCC) generated from scratch (as a store bought one is very expensive) ( Ill add the assemby for the source as well ;) )
5. Multimeter
6. LCD display
7. Raspberry pi 4B (optional)

• Final set up of the components connected:

variations in reading depending on voltage: (Expected reading of 2v -->gives around 1v) output through a multimeter:

1. Output of the Voltage source --> Takes rounded values.
2. Should set up lcd
3. direct connection to cloud (must be set up) -->Used esp01 for connection to cloud (thinkspeak) using AT commands and it's not working for now.

I took wayy more time than what I had promised due to un forseen conditions
