NOTE: All pin assignments are to PHYSICAL pins, not GPIO IDs. Refer to following image for reference
https://az835927.vo.msecnd.net/sites/iot/Resources/images/PinMappings/RP2_Pinout.png

Pin 1 = 3.3v for BMP180 sensor
Pin 3 & 5 = Signal for BMP180 sensor
Pin 7 = Signal for DHT11 sensor --- "dht11.py" code already has correct GPIO pin coded
Pin 9 = Ground for all sensors
Pin 11 = Signal for water level sensor
Pin 2 = 5v power for DHT11 and water sensor
