The raw source of the sketch example is visible here. ここまでの技術部では、LEDの点灯制御、PWM制御による明るさ制御などを扱ってきました。そろそろ少しステップアップということで、センサを扱ってみたいと思います。, センサ（sensor）は、人間でいうと目、耳、鼻などの感覚器官の役割を果すもので、身の回りの様々な現象を感知することができます。自動ドアで人間を感知するものや、暗くなると自動的に点灯する街灯などがイメージしやすいですね。もちろん、人間には感知できない情報を捉えるセンサもあります。赤外線センサや超音波センサなどです。, センサとマイコンを組み合わせることで、電子制御の幅が大きく広がります。今回の技術部では、LM35という温度センサを用いてArduinoで温度測定をしてみます。, LM35の外観です。見た目はトランジスタとそっくり（というか同じ）なので、混同しないように注意が必要です。, LM35はArduino関連の書籍などにもよく登場するセンサで、その扱いやすさが特徴です。上の秋月のページからデータシートも見られますが、重要と思われる部分をピックアップしてみます。, ・4~20Vの電源電圧で動作（つまり5Vで動く→Arduinoからの電源供給で使える）・出力電圧は０ｍV+１０ｍV/℃（気温０度で０ｍV、以降１度上昇毎に１０ｍVづつ増加→リニアでわかりやすい）・-55~+150℃まで測定できる（ただし精度は0.5℃程度→精密な測定には不向き）, というかんじです。ようするに値段が安くてデータの処理がわかりやすくてある程度広い範囲の温度が測れるよってことです。電子制御で気温を測ってみるにはちょうどいいセンサといえると思います。100円で買えるので、間違って破壊しても精神的ショックが少なくすみます（重要）, また、データシートをみるとわかりますが、このLM35は様々なパッケージのものがあって、金属制のものやICチップ状のもの、色々です。形状によってピンの配置が違うので逆電圧をかけないようによく確認して下さい。（壊れると精神的ショックが）, このセンサ、気温１度毎に出力電圧が10ｍVずつ上昇するので、出力電圧の値をArduinoで読み取ってやればそこから気温が計算できる、という仕組みです。ということは、Arduinoでやることは「電圧の大きさを読み取る」ということになります。, Arduinoで電圧の大きさを読み取るためには、A/D変換という方法を使います。（アナログ-ディジタル変換）, 読み取る電圧はアナログ量、一方Arduinoマイコンが扱うのはディジタル量であるので、変換してやらないとArduinoで扱うことが出来ない、ということですね。, なので、Arduinoでは4.9ｍV以下の電圧変化は検出できない、という事になります。, ArduinoでA/D変換を行う場合、analogRead関数を利用します。対応いているピンはA0~A5ピンです。, それでは、LM35の出力電圧をArduinoで読み取るとどんな値が見えるのか試してみましょう。, このように配線を行います。前述の通り、ピン配置はパッケージによって異なるのでよく確認して下さい。, A0ピンの電圧を読み取って、そのままシリアルモニタに表示しているだけのプログラムです。シリアル通信については、以前の記事を参照してください。※A0~A5ピンについては、pinModeの設定は必要ありません。, プログラムを書き込んでシリアルモニタを表示すると、A/D変換された電圧の値が表示されます。この値は、「５Vを1024等分した最小単位何個分か」、を意味しているので、ここから出力電圧を計算するには、以下の計算が必要です。, Vout = 60 * 5 /1024 = 0.293 ［V］ = 293 ［ｍV］, これでLM35の使い方がマスターできたので、まとめとして「一定の温度（30℃）を超えたらLEDを点灯させる」システムを考えてみます。今回はArduino内蔵LEDを用いるので、配線はさきほどのままでOKです。, 色々小難しい勉強にもなりましたが、一度理解してしまえば簡単な配線とプログラムでセンサを使いこなすことができました。少し応用すると、複数の場所の気温を比較したり、センサに防水処理をすれば水温なども図ることができます。プログラム的には難解になりますが、一定間隔で温度情報を記録することも可能です。, 二児の子育てと仕事に奮闘しながら、充実した人生を送るためのプロジェクト。30代の子育てパパが頑張って執筆しています。.
