我們去年發布的 PiM25 專案被 MagPi 77 報導了(第八頁)!

We like to see citizen science here at The MagPi – you may remember Raspberry Shake, the seismometer add-on for the Pi, which crowdsourced seismic activity.

In East Asia, we hear a fair bit about issues with air quality, so we weren’t too surprised when Nai-Wen, organiser of the Taiwanese Raspberry Pi community, told us about a project using open-source software to keep track of air pollution in Taiwan.

“PM2.5 is a citizen science project. We provide instructions and open-source code to help people create and customise their own PiM25 box.” Nai‐Wen tells us via email.
“When the PiM25 box is ready, air quality and GPS data can upload to the Taiwan’s PM2.5 Open Data Portal (Location Aware Sensing System, or LASS) 24/7. Everyone can see the open data from the map (”

Mapping the air The visualisation is fairly straightforward, colour-coding the results.
Taipei, the capital, is fairly clean, but the west coast tends to be a little polluted. Data is updated on the fly, so these values may change depending on wind, time of day, and even time of year. “We wanted to build up an easy-to-use airbox and visualise the environment information,” Nai-Wen explains.

“We hope the awareness will increase their interest in improving their air, health, life, and planet.”

Raspberry Pi in Taiwan While it’s sometimes easy to think of the Raspberry Pi community as being largely UK based, it’s important to remember that people use it all around the world, including in Taiwan. Starting in 2013, there have been regular meet-ups every month or two, organised by Nai‐Wen: “We have workshops, hackathons, and an occasional book club event. The community also helps to organise open-source conferences, such as PyCon Taiwan or MakerConf Taiwan.”

We look forward to seeing what else comes out of the Taiwanese Pi community

PiM25 靈感

PiM25 靈感來自於中研院陳伶志老師和哈爸所發起的 LASS環境感測器網路系統。LASS 是目前國際知名的公民專案,也有很多媒體採訪報導與演講分享,例如 TEDxTaipei今週刊等等。但過去大部分是使用聯發科 LinkIT 7688/7697 或是瑞昱阿米巴等,使用 Raspberry Pi 的案例較少,因此我們也發布一個版本,希望 Pi 的愛好者也可以一起守護台灣。

PiM25 特色

PiM25 採用 PIGPIOd 控制 GPIO 腳位,特色之一是可同時讀取多組 UART 設備,例如可同時讀取攀藤 G5 PMS5003 PM2.5 感測器和 GPS 資訊。特色之二是我們將會發布 Blockly 的圖形操作界面,可以讓小朋友也很容易使用拖拉式的方式上手。

PiM25 版本

目前 PiM25 有兩個版本,第一個是包含多種感測器的完整版,包括攀藤 G5 PMS5003 PM2.5 感測器ublox NEO-6GPSDHT22 溫濕度感測器,和 I2C OLED(0.96″),我們做了一版 Pi Zero W 的展示
第二個版本是中研院陳伶志老師的輕量化版本,只使用了攀藤 G5T PMS5003T PM2.5 粉塵濃度/溫濕度二合一感測器GPS,就可讀取基本的 PM2.5, 溫濕度和經緯度數值。
