Description: The plan is to implement plant sensing technology for a Groworld installation at Camp Pixelache. The circuitry has been enhanced for durability through soldering. The circuit diagram's component values are influenced by available surplus and donated stock but are based on Nik's original design. The code reads data from an Arduino in Fluxus, featuring hastily written auto-calibration that records the highest and lowest values from each sensor, scaling the output between 0 and 1. This method may not be suitable for all situations. The program reads values from the Arduino via the serial port and provides them to the game. The implementation includes definitions for reading light and moisture sensor values, calibration, and updating sensor readings.
The schematic involves various components working together to facilitate plant monitoring. The Arduino microcontroller serves as the central processing unit, interfacing with light and moisture sensors. The light sensor measures ambient light levels, while the moisture sensor assesses soil moisture content. These sensors output analog signals that the Arduino reads through its analog input pins.
The calibration process is crucial for ensuring accurate readings. The initial step involves recording the highest and lowest values detected by each sensor. This establishes a dynamic range for each sensor, allowing the system to scale the output values between 0 and 1. The calibration function uses a formula to fit the raw sensor readings within the defined range, which is essential for interpreting the data accurately.
The code employs a serial communication protocol to transmit sensor data to an external application, allowing real-time monitoring and interaction. The program continuously checks for data from the sensors, updating the current readings and recalibrating as necessary. This ensures that fluctuations in environmental conditions are accounted for, providing reliable data for the Groworld installation.
In summary, the circuit design integrates robust hardware and software components to facilitate effective plant monitoring, ensuring that the Groworld installation at Camp Pixelache can thrive through informed environmental management.The plan is to have some plant sensing working for a groworld installation we are doing at Camp Pixelache so I`ve made the circuitry a little more durable with a bit of soldering: Here`s the circuit diagram the values of components are influenced by what I happen to have in my collection of surplus/donated stock but are based on Nik`s original circuit: This is the code that reads the arduino in fluxus.
