Pseudocode

Assign sensor to pin A3  
Assign BLE service with UUID 180C  
Assign BLE characteristic with UUID 2A56, read and notify, max 50 bytes 
Set delay value to 250  
Set time window for average to 10 seconds  
Set max readings to (1000 / delay) * time window  
Set scale factor to 5.0  
Set reference voltage to 5.00  
Set forward voltage drop to 1.8  
Set estimated voltage to forward voltage + 0.45  
Set reading index to 0  
Set total readings to 0  
Set peak voltage to 0  
Start Serial  
If BLE fails to begin stop execution  
Set BLE name to VoltageSensor  
Advertise BLE service and characteristic  
Loop forever  
Read analog voltage from sensor  
Convert to output voltage using 1023 and reference voltage  
Scale to input voltage using factor  
If voltage is less than or equal to estimated voltage multiply it by 2  
Else add estimated voltage  
Add adjusted voltage to readings array  
Update average of readings  
If adjusted voltage is greater than peak voltage set peak voltage to it  
If adjusted voltage >= 5 set water condition to Harsh  
Else if >= 2 set water condition to Moderate  
Else if >= 0.8 set water condition to Mild  
Else set water condition to No waves  
If adjusted voltage > 0.3 set status to Generating  
Else set status to Idle  
Print adjusted voltage and water condition  
Print average voltage  
Print peak voltage  
Format data string as adjusted voltage, water condition, average, peak, and status  
Send data string over BLE  
Wait delay time before next loop
