Abstract
The soil level of moisture is one of the important aspects, which in turn controls the caliber of the vineyard grown in vineyards. The primary objective of the research is to investigate the development of an affordable soil water sensor, that can be used in a ZigBee fine mesh network.
ZigBee is a new mesh networking standard, which will places focus on low cost messfuhler networks and energy conservation. The development target for ZigBee is remote control monitoring and control applications. Manufacturers remain improving their ZigBee gadgets and ZigBee software piles.
The ZigBee based The state of texas Instruments CC2430 microcontroller was selected because the wifi sensor components for this research.
Micro climate weather train station was
made to monitor the vineyard environmental data just like temperature, pressure, sunlight, moisture, leaf wetness and soil moisture and temperature. The wireless dirt moisture sensor is a single main element of the tiny climate weather station. The 2 probe dirt moisture sensor uses the standard principle of any series given Hartley oscillator frequency switch due to the different dielectric regular of the ground according to the garden soil Volumetric Drinking water Content (VWC). When the garden soil VWC boosts, the dielectric constant likewise increases while the oscillator frequency diminishes. This standard principle is used measure the ground moisture content material.
Both the soil moisture sensor and mini climate weather station have been developed and tested with the ZigBee fine mesh network topology. The soil moisture sensor was analyzed and calibrated, using two different garden soil types.
This kind of research has efficiently achieved their objectives and identifies areas for future development.
