IoTデータ 可視化サービスAmbientにENV III UNITのデータを送る

以前から触ってみようと思ってやっていなかったIoTデータを可視化するサービスAmbientを試してみました。

https://ambidata.io/

使い方は、書籍「IoT開発スタートブック ── ESP32でクラウドにつなげる電子工作をはじめよう!」やAmbientの公式ドキュメントに詳しく書かれていますが、試した内容をメモとして残しておきます。

Githubリポジトリ ESP8266/ESP32用Arduino・Ambientライブラリー にもサンプルが掲載されているのでこちらも参考になります。

センサーは、M5Stick-C ENV III Unitを使います。

ENV III Unit with Temperature Humidity Air Pressure Sensor (SHT30+QMP6988)
ENV III SKU:U001-C Description ENV III is an environmental sensor that integrates SHT30 and QMP6988 internally to detect temperature, humidity, and atmospheric pressure data. SHT30 is a high-precision and low-power digital temperature and humidity sensor, and supports I2C interface (SHT30:0x44 , QMP6988:0x70).QMP6988 is an absolute air pressure sensor specially designed for mobile applications, with high accuracy and stability, suitable for environmental data collection and detection types of projects.Product Features Simple and easy to use High accuracy I2C communication interface HY2.0-4P interface, support platform UIFlow , Arduino 2x LEGO compatible holes Include 1x ENV-III Unit 1x HY2.0-4P Cable Applications Weather station Storage barn environment monitoring Specification Resources Parameter Maximum temperature measurement range -40 ~ 120 ℃ Highest measurement accuracy 0 ~ 60 ℃/±0.2℃ Humidity measurement range/error 10 ~ 90 %RH / ±2% Maximum measured value of air pressure/resolution/error 300 ~ 1100hPa / 0.06Pa / ±3.9Pa Communication protocol I2C: SHT30(0x44), QMP6988(0x70) Working temperature 32°F to 104°F (0°C to 40°C ) Net weight 5g Gross weight 17g Product Size 24.2*32.2*8.1mm Package Size 67*53*12mm Case Material Plastic ( PC ) ENV version scheme comparison ENV I ENV II ENV III DHT12+BMP280 SHT30+BMP280 SHT30+QMP6988 PinMap M5Core(PORT A) GPIO22 GPIO21 5V GND ENV III Unit SCL SDA 5V GND Schematic Related Link Datasheet QMP6988 SHT30 Learn M5stack based PFD (Primary Flight Display) An attempt to create a realtime “Artificial Horizon” on the M5.

今回HATじゃなくてUNITの方にした理由としては、M5StackやATOMなどでも使い回したいという理由でUTNIにしてみました。

M5Stick-Cで光センサユニット(LIGHT UNIT)を試す

M5Stack-Cで、光センサーのユニットLIGHTを試してみました。

LIGHT UNITの光センサは、フォトレジスタ(CdSセル)が組み込まれているモジュールで、光の強さをアナログおよびデジタルで読み取れます。

公式リファレンスのページ: Light – M5Stack Docs

プログラムは、上記の公式リファレンスのページで紹介されているサンプルを修正してみました。

Github: M5Stack/examples/Unit/LIGHT/LIGHT.ino

公式リファレンスのM5Stack Coreを利用した例と同じ様に、LIGHT UNITから読み取ったアナログとデジタルの値をLCDに表示します。
