This research implement microcontroller wireless data communication on automatic irrigation. Microcontroller unit (MCU) is used to read soil moisture level by using Soil Moisture sensor. Sensor values need to be sent to main controller (server computer) for monitoring. Past research (Nugroho 2011) has implemented serial cable for communication between field controller and main controller, but it will be inefficient for field application because serial cable implementation would be difficult if the field is far from the computer. Therefore, wireless data communication needed. XBee was choosen because compared to other wireless devices (Bluetooth, GSM, and WiFi), XBee has the lowest power consumption, lowest cost and the most suitable for monitoring and controlling. XBee performance is tested using the number of data packet loss. From the test result, the best distance to place the field controller is obtained, which is less than 20 meters from the main controller. For a better performance in decreasing the data packet loss incurred by the longer distance, it is advised to use the newer XBee series.
