Aim

To monitor the tunnel environment except the center and end ares.

Construction

1. Sensor (Raspberry Pi 3 based + EPICS) 2. Monitor map system (software: EPICS based?)

Monitor map

We should decide the required sampling rate and resolution. Target: 10 Hz sampling

1. Temperature (SHT-25)

2. Humidity (SHT-25) https://strawberry-linux.com/catalog/items?code=80025

3. Air pressure (BM1383GLV: Rohm) http://www.rohm.co.jp/web/japan/news-detail?news-title=2014-12-11_ad_pressure

4. Magnetic field (BM1422GMV: Rohm) http://www.rohm.co.jp/web/japan/news-detail?news-title=2015-06-17_ad_mi

5. Wind speed / direction

How many?

Every 200 m, we put the sensor. The estimated number of the sensors is 30.

Budget

500,000 JPY from Shikano Group at Institute for Molecular Science (IMS), National Institutes of Natural Sciences
