ESP32フィールド観測システム（温度・湿度・PIR・RSSI）
完全仕様書（コピペ再現版）
作成日: 2026-01-05
1. システム概要
本書は、ESP32（WROOM/DevKit系 または ESP32-C3）複数台をフィールドに設置し、DHT11（温度・湿度）とPIR（人感）を計測して、WiFi経由でRaspberry Pi 5のMosquitto（MQTT）へ送信、Node-RED Dashboard（/ui）でグラフ表示し、外付けSSDへCSV保存するシステムの「完全再現」手順です。
初心者が、手順どおりに環境を作り、コードをカット＆ペーストして同じシステムを再現できるよう、配線・設定・コード・Node-REDフローJSONをすべて含めます。
2. 構成（全体アーキテクチャ）
データの流れ：センサー（DHT11/PIR）→ ESP32（WiFi）→ MQTT（Mosquitto）→ Node-RED → Dashboard（/ui）＋ CSV保存（SSD）
トピック設計：
・sensors/<NODE>/dht11 : {node,temp,hum,pir,rssi}
・sensors/<NODE>/pir : {node,pir,rssi}（変化時のみ）
NODEは field01 / field02 / field03 を想定します。複数台運用では NODE 名だけを変えて同じスケッチを書き込みます。
3. 必要機材
フィールド側（各ノード=1台あたり）：ESP32（WROOM/DevKit系 または ESP32-C3）、DHT11、PIR、ジャンパ線、電源。
サーバ側：Raspberry Pi 5、Mosquitto、Node-RED（Dashboard）、外付けSSD（例：/media/PI_SHARE_500G）。
4. 配線（ESP32側）
本書では以下のGPIOを使用します（あなたの既存構成に合わせています）。
・DHT11 DATA → GPIO4
・PIR OUT → GPIO2
VCC/GNDは各モジュール仕様に従い、ESP32のGNDは必ず共通にします。
5. 事前準備（Raspberry Pi：Mosquitto / Node-RED / SSD）
5.1 MQTT動作確認（例）
mosquitto_sub -h localhost -t “sensors/#” -v
5.2 SSD保存先フォルダの準備（例）
sudo mkdir -p /media/PI_SHARE_500G/sensor_logs
sudo chown -R $USER:$USER /media/PI_SHARE_500G/sensor_logs
6. Arduino IDE 設定（Windows 11）
6.1 ボードマネージャ：ESP32 by Espressif Systems をインストール
6.2 ライブラリ：PubSubClient、DHT sensor library（Adafruit）
6.3 ボード選択：WROOM/DevKitは該当するESP32 DevKit、C3はXIAO ESP32C3等（S3と混同しない）
7. ESP32 スケッチ（WiFi + MQTT：WROOM/DevKit用）
/*
===== フィールド観測ノード（WiFi + MQTT）安定版 =====
– DHT11（温度・湿度）と PIR（人感）を読み取り、MQTTで送信します。
– RSSI（WiFi受信感度, dBm）も同時に送ります。0 に近いほど強い（例：-50は強い、-90は弱い）。
– 送信先トピック:
sensors/<NODE>/dht11 : {node,temp,hum,pir,rssi}
sensors/<NODE>/pir : {node,pir,rssi}（変化時のみ）
– 複数台運用：NODE 名だけ field01/02/03 に変えて焼きます。

9. Node-RED フローJSON（/ui + PIR安定化 + RSSI棒グラフ + セッションCSV）
インポート：Node-RED右上メニュー → Import → Clipboard → 下のJSONを貼り付け → Import → Deploy
Dashboard： http://<RasPiのIP>:1880/nodered/ui
使い方
- Node-RED画面右上メニュー → Import → Clipboard
下のJSONを貼り付け → Import - Deploy
- Dashboard：http://<RasPiのIP>:1880/red/ui (あなたの環境に合わせること）
10. 保存データ（CSV）の確認方法
保存先（例）
/media/PI_SHARE_500G/sensor_logs/
基本確認（Raspberry Pi）
1) ファイル一覧（サイズと更新時刻）
ls -lh /media/PI_SHARE_500G/sensor_logs
2) 追記されているか（末尾を表示）
tail -n 5 /media/PI_SHARE_500G/sensor_logs/field01.csv
3) 先頭を表示（ヘッダがある場合や形式確認）
head -n 5 /media/PI_SHARE_500G/sensor_logs/field01.csv
4) 行数（データ件数の目安）
wc -l /media/PI_SHARE_500G/sensor_logs/field01.csv
5) 更新が止まっていないか（更新時刻の変化を見る）
watch -n 2 ‘ls -lh /media/PI_SHARE_500G/sensor_logs’
Node-RED側の確認ポイント
・fileノードの警告（プロパティ未設定）が出ていないこと
・createDir=false の場合、事前に sensor_logs フォルダが存在すること
・書き込み権限：Node-RED実行ユーザがそのフォルダに書き込めること（例：ls -ld で確認）
11. CSV 1行データの読み方
例：
2026-01-03T08:01:29.080Z,field01,17.0,51.0,0,-90
この1行は、カンマ区切り（CSV）で次の順番です。
1) timestamp：日時（ISO 8601）。末尾のZはUTCを意味します。
2) node：ノード名（field01/field02/field03 など）。
3) temp：温度（℃）。DHT11は分解能が粗く、誤差も大きい点に注意。
4) hum：湿度（%）。同様に誤差やばらつきがあります。
5) pir：人感（0/1）。0=非検知、1=検知。環境ノイズで1が続く場合は設置・電源・配線・Pull設定、またはNode-RED側のRBE/Delay等で安定化します。
6) rssi：WiFi受信感度（dBm）。0に近いほど強い（例：-50は強い、-90は弱い）。
時刻の注意（UTC→日本時間）
Node-REDの例では new Date().toISOString() を使うためUTCになります。日本時間（JST=UTC+9）で見たい場合：
・CSVはUTCのまま保存し、解析時にJSTへ変換（推奨：後処理が楽）
・またはNode-RED側でJSTの文字列にして保存（例：functionノードでtoLocaleString(‘ja-JP’, { timeZone: ‘Asia/Tokyo’ })）
12. RSSI（受信感度）の目安
RSSIは WiFi の受信信号強度（dBm）です。数値は「0に近いほど強い」ことを意味します（例：-50dBmは強い、-90dBmは弱い）。
本システムでは、各ESP32がMQTT送信時点で WiFi.RSSI() を取得し、payloadに rssi として含めています。
目安（環境により変動します）
・-30 ～ -55 dBm：非常に良い（近距離／見通し良好）
・-56 ～ -67 dBm：良い（安定しやすい）
・-68 ～ -75 dBm：普通（運用可能だが遮蔽物で不安定になり得る）
・-76 ～ -82 dBm：弱め（遅延・再送・切断が出やすいことがある）
・-83 ～ -90 dBm：かなり弱い（途切れやすい。設置位置・アンテナ・中継検討）
・-91 dBm以下：限界付近（接続維持が難しいことが多い）
注意
・RSSIは瞬間値で揺れます。Node-REDのグラフで「傾向」を見てください（平均的にどの範囲にいるか）。
・屋外は天候・植生・人や車の動きで変動します。設置後に数時間～1日ログを取り、最悪値も確認します。
・RSSIが悪いのに通信が安定している場合もあります（再送やスループットの要求が低い場合）。逆もあります。
