Datalogger network
Dataloggers are devices that control and collect data from sensors, which allows data to be displayed on different platforms. A network of dataloggers are embedded throughout Global Flora and operate 24/7 to collect, compile, and publish data from the sensors. The datalogger network was designed to maximize versatility, so students and researchers can connect many types of sensors or create and use their own.
Above is a video on the components within select benches in the greenhouse. Learn more below!
Network Components
The datalogger receives the data from the sensor network and makes it available for transfer through either ethernet or SD card. Both
Digital and Analog functions can be performed by the datalogger. It has 8 Digital output/input ports and 16 Analog ports. Analog functions are on page 6 and Digital functions are on page 7 of the Specifications handbook.
The SDI-12 Junction Box is commonly used in Global Flora. It allows the datalogger to take in more wires by converting multiple inputs into a single one. The sensors must have SDI-12 capability to connect to the junction box. If not, they will be attached directly to the datalogger.
Junction box markings
Symbol | Name | Function |
|---|---|---|
D | Data | Sends data from the sensors |
G | Ground | Grounds the voltage from the battery |
P | Power | Manages power output |
S | Shield | Cleans up the signal/data (D) |
The battery has an output of 12 volts. Each port of the datalogger uses 5 volts.
You can add your own datalogger or microcontroller into the available data benches.
Dry biome
- The datalogger and sensor power sources are stored in the wooden bench in front of the exit on the lowest level of the dry biome.
Wet biome
- The datalogger and sensor power sources are stored in the first long bench on the lowest level of the wet biome.
