| + | 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. | ||

| Each DHT11 sensor requires 3.3 - 5V, ground and a digital input pin. Pinouts are shown below: | Each DHT11 sensor requires 3.3 - 5V, ground and a digital input pin. Pinouts are shown below: | ||

| - | ===== Software ===== | + | ==== 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 | ||
| + | 5V +5V | ||

| + | For antennatempke the IP address should be 131.217.61.29. | ||
| + | |||
| + | Edit ''/etc/dhcpcd.conf'': | ||
| + | |||
| + | <code> | ||
| + | interface eth0 | ||
| + | static ip_address=131.217.61.28/26 | ||
| + | # /26 = netmask of 255.255.255.192 | ||
| + | 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. | ||
