+====== Monitoring at AuScope sites ======
-First system will go in at Katherine soon. There are two raspberry pi PCs, one for the antenna and one for the maser room.
+Raspberry Pi PCs are being installed at the sites for monitoring temperature and humidity in the antenna and (in Katherine) any vibrations on the maser.
-===== Access: =====
+First system is in at Katherine which has two raspberry pi PCs, one for the antenna and one for the maser room. The other sites will have PCs in the antenna.

+====== Hardware setup and configuration ======
-===== Hardware setup =====
+Katherine is set up with a different set of temperature and humidity sensors to the other two sites (DHT11 compared to DHT22). The Raspberry Pi in the maser room also has an Arduino board attached to it for the accelerometer and some analog temperature sensors.
+===== Katherine =====
+Connect the Raspberry Pi to the Arduino via a USB cable. The Arduino will get power via the cable but it's a good idea to also give the Arduino power via a DC power supply as this provides a more stable reference voltage for the analog sensors.
+==== DHT11 temperature and humidity sensors ====
 Each DHT11 sensor requires 3.3 - 5V, ground and a digital input pin. Pinouts are shown below:

+==== IR transmitters, receivers ====
+These have three pins as well:
+<code>
+pin    connection
+---    ---------------
+-      GND
+middle +5V
+S      digital signal
+</code>
+Connect them to the Raspberry Pi. Any GND or +5V pin will be fine.
+Use any digital pin on the Pi and make sure they are set to "False" in ''TempHumid.conf'' (you can give them an appropriate label though). See below.
+==== Accelerometer ====
+This should be connected to the Arduino:
+<code>
+module pin    Arduino connection
+----------    ---------------
+VCC           +5V
+X out         A0
+Y out         A1
+Z out         A2
+GND           GND
+</code>
+Attach the accelerometer to the maser (or whatever you want to measure). You might want to align it according to the orientation diagram on the module.
+==== Analog (Eric) Temperature/Humidity Sensor ====
+This should also be connected to the Arduino:
+<code>
+module pin    Arduino connection
+----------    ---------------
+T             A3
+G             GND
+H             A4
+V            +5V

 Edit the ''TempHumid.conf'' file accordingly (see below), then either restart the software by typing CTRL-C in the start_THRecord xterm or by rebooting the Pi.

   * ''start_THRecord.sh'' and ''start_THServer.sh'' are started automatically after the RPi boots into a desktop session, so a reboot of the RPi should start these processes. They are called from ''~/.config/lxsession/LXDE-pi/autostart''. Edit this file if you want to change what happens when the desktop starts.

+===== Katherine =====
+===== Accelerometer, Analog temp/humid monitoring Software ======
+A work in progress... The accelerometer data are available via the web but an alarm system for jolts needs to be implemented. At the moment, no analog temp/humid sensors are in use.
+===== Software for IR remote control of aircon ======
+A work in progress... Some preliminary work has been done but we are having trouble 'learning' the remote.
+===== Access: =====
+Access via VNC or SSH:
+username is ''pi'', password is as usual
+====== Network config =====
+This should be done already, but just in case...
+  * For masertempke the IP address should be 131.217.61.28.
+  * For antennatempke the IP address should be 131.217.61.29.
+Edit ''/etc/dhcpcd.conf'':
+<code>
+interface eth0

+static routers=131.217.61.1
+static domain_name_servers=131.217.0.19
+</code>
+The hostname should be correct but can be set via the Preferences/Raspberry Pi configuration GUI on the desktop.
+Reboot.
