Current Status

1. Sensors except for one sensor were received. -> Printed circuit board assembling will be started.

2. Drawing the box for Raspeberry Pi and sensors -> We are waiting for the test box.

3. Software: almost done. (database)

Not yet decided

1. Power cable 3 m (Internal budget will be used.)
2. LAN cable ?? m (10 m?) (Which grant will be used?)
3. IP issue (KAGRA DAQ IP system) At least 12 IPs are required.

Aim

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

Construction

1. Sensor (Raspberry Pi 2B based + EPICS)
2. Monitor map system (Not yet)

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 (AMI306R: Aichi Steel)

How many?

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

Updated information: initial install number at the network point w/ wired LAN is 6 for each arm.
