あくあたん水槽監視・制御ユニット

IMG_7726こちらは2つめのRaspberry Piです.水槽や環境の状態をモニタして,照明・ファンの制御を行う部分です.センサーには温度センサーDS18B20が4基,大気圧センサMPL115A2が1基,湿度センサDHT11が1基搭載されています.また,MOSFETで3基の冷却ファンを制御し,ACリレーで3基のAC電源を制御できます.

IMG_7739裏側から,Raspberry Piを外した状態はこんな感じ.ad-hocに回路を追加してしまったので,きれいな基板ではありません.もっと小さい面積に詰められたはずなんですが…

IMG_7785あくあたん弐号機義体部はRaspberry Piで制御する移動型カメラ台+自動給餌器です.左側がUSBカメラ2基(広角+赤外線)で,この部分は上下動も可能です.

左右への移動はタイヤで行います.上下左右の動力にはLEGOの旧型モーターを2基使い,DRV8830によって制御しています.モーターの定格を遙かに下回る電圧しか与えられませんが,思いの外さくさく動きます.

2 months

After 2 months, my daily life finally become stable.
Taiji is going to a kindergarten and learning English step by step.
He can remember what native speaker said by ear and can pronounce as he listen. Very good job…

I thus started research works with SAIL.
We are now discussing three theme that can be collaborated with each other.
Students in KIT also involved in this collaboration, and perhaps I will invite some of them to Canada during my stay.
