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)

  3. Air pressure (BM1383GLV: Rohm)

  4. Magnetic field (BM1422GMV: Rohm)

  5. Water-proof Camera

How many?

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