ZeMo (derived from ZEbrafish MOnitor) is designed to be a low-cost, automated aquarium monitoring system. It was created specifically with research zebrafish in mind, but can be used for any aquatic species. Although customizable, it is designed to read water temperature, pH, Conductivity (salt content), and Dissolved Oxygen. It also includes the ability to view parameter histories online, and to receive remote notifications when one or more measurements are outside the specified ranges. Assembly of the device is designed to minimize the technical expertise needed, but should be done by someone with basic soldering and command line experience.

ZeMo uses a raspberry pi zero w to take measurements and post to the web. This requires installation of the raspbian OS and ZeMo software onto a microSD card (8 GB recommended) before device assembly. The device is then assembled and ZeMo setup on the device.
- Download and install PiBakery from http://www.pibakery.org/
- Open a new PiBakery window and create a custom script by connecting the following
blocks (or you can import the ZeMoPiBakeryRecipe.xml file on Github):
- On first boot
- Set user password (insert your desired password)
- Set hostname (must be different from any others you have tied to your account)
- Enable automatic loading of I2C kernal module
- Set Pi Zero OTG Mode to Ethernet (usually defaults are fine)
- Reboot
- On every boot (this starts a new chain of blocks)
- Enable VNC
- Write to SD card
- Assemble ZeMo
- Plug into USB port and allow to startup.
- Open terminal window on computer
- Connect by typing ssh pi@rack1.local (substitute hostname you entered in step 2 for "rack1")
- Edit the wpa_supplicant to connect to the internet. This step depends on your particular network configuration. More information is available from here (https://www.systutorials.com/docs/linux/man/5-wpa_supplicant.conf/) or from your network administrator.
- Run command: sudo reboot
- After restarting, reconnect by ssh (see step 7)
- Run command: sudo raspi-config
- Change timezone, language, etc. for your location. See http://geek-university.com/raspberry-pi/internationalisation-options/ for more information.
- Run command: git clone https://github.com/ZeMoProject/ZeMoCode
- Run command: bash ~/ZeMoCode/SetupZemo.sh
- Respond to prompts:
- Enter ZeMo Account name. If you have not set one up, you may do so at zemoproject.org
- Select configuration:
- PiTFT 2.4", 2.8" or 3.2" resistive (240x320)
- PiTFT 2.2" no touch (240x320)
- PiTFT 2.8" capacitive touch (240x320)
- PiTFT 3.5" resistive touch (320x480)
- Quit without installing
- Select rotation:
- 90 degrees (landscape)
- 180 degrees (portait)
- 270 degrees (landscape)
- 0 degrees (portait)
