Arduino PH Meter Board Only

Arduino PH Meter Board (Board Only)

Feature :
This board can measure the PH reading ,and also build in two temperature sensor , one is for measure room temperature(LM35) , one is for measure water termperature(DS18B20). Provide Arduino sample code for work with Arduino UNO and LCD Keypad Shield.I use this board on my aquarium for monitor the water 's temperature and PH reading.
