“…Soil's moisture sensor is SWR-3 made in Beijing Zhihai Electronic Instrument Factory, which has the characteristics of high accuracy, fast response, good interchangeability, low price and so on. The working voltage is 10 ~ 30V, response time is less than 1 second, accuracy is±2% (m³ / m³) within 0 ~ 50% (m³ / m³) range [6], output signal voltage is 0 ~ 2.5V. The current soil's water content is got from AD of the microcontroller.…”

Combining with the modern orchards’ large-scale development mode and requirements of precision agriculture construction, we designed an orchard long-distance intelligent irrigation system. GPRS network and ZigBee wireless sensor network composed of microcontroller, soil moisture sensor, zero-pressure solenoid valve and CC2430 are used in this system to transmits and control the data. By analyzing the soil’s water content of the sample and combining the advanced setting threshold, the system can send order to control the zero-pressure solenoid valve so that the long-distance control and intelligent irrigation are achieved. When puts into practice, the system shows a stable performance. It meets the design requirements in data acquisition, data transfer and long-distance control and deserves better promotion.
