Interesting example is a plant of irrigation system, detecting humidity sensor will be buried in the soil, in accordance with the corresponding parameter set, that's grown plants, then, when the soil moisture is insufficient, the sensor will be able to send the user mobile phone to remind, tell you need watering.It can also be used for large area crop irrigation, and can even combine different application - for example, connect it and weather related application, so, when the system is that the weather is very dry, hot, can increase the humidity;
   And if the next few days are likely to rain, the irrigation system can be temporarily stopped.In addition, because of the low energy consumption of bluetooth technology, it can only use small solar panels on the sensor on the farm to complete the power supply without erecting additional lines.
