Watery detection to sprinkling

這個系統，由水量偵測結果再通知灑水器間斷澆水。費用大概花費台幣300元。
This system through the result of soil watery to decide the sprinkling moment. It costs around $10 USD.

系統可以設定澆水時機。當澆水時機，灑水器會打開10秒，之後會關閉1分鐘，好讓水份有時間滿滿滲入泥土中。如此循環，一直到水份高於設定值。
It sets the moment level to make sprinkle. When the moment arrived, the sprinkler will open for throw out water in 10 seconds. And then, suspend 1 minute for drain water into soil. Cycle this steps till water level up to the level what we set.

目前的設定值是在電阻大於700K歐姆時打開澆水時機。水份達到足夠（低於700K歐姆）時，離開澆水時機，進入水份偵測狀態。
As APP show, currently, I set 700K Ohm as the threshold to get into the sprinkling moment.



原子筆桶是個很好的水管連結器。

水管結點利用AB膠固定。

在軟水管內側打出灑水孔。

利用白鐵線固定軟水管。

快速排水的紅陶盆（The red pottery container is easy to drain water)

紅陶盆排水能力很好，即使冬天，每天還是要加幾次水。利用紅陶盆來測試水含量，比較能夠縮短測試時間。

（Even in winter, it still need fill water to red pottery several times)

測試新電路 （Test a new circuit. It uses TI cc 2541 BLE, and prepare for sprinkle adaption)

Changed Bluetooth module

For the battery energy consuming test, I changed the Bluetooth module from CSR Bluetooth Version 2 to TI's CC2541 BLE.
