Hi guys, Ive been able with some friends to ‘‘build’’ up a sensor device prototype for agricultural concerns: with the following specs:
Arduino UNO board: http://arduino.cc/en/Main/arduinoBoardUno
Base Shield: http://www.seeedstudio.com/wiki/Grove_-Base_Shield_V1.3
GPRS Shield: http://www.seeedstudio.com/wiki/GPRS_Shield_V2.0
GPS Sensor: http://www.seeedstudio.com/wiki/Grove-GPS
Soil humidity Sensor: http://www.seeedstudio.com/wiki/Grove-_Moisture_Sensor
We are tryin now to add a PH sensor to it. Would someone have any advice regarding what is needed in terms of hardware ?
