Test Data of the Wireless Sensor Network for Express Diagnostics a State of Plant Based on the Chlorophyll Fluorescence Induction Effect

This dataset contains test results from a wireless sensor network developed by the V.M. Glushkov Institute of Cybernetics of the National Academy of Sciences of Ukraine. The WSN is designed for express diagnostics of state of plant based on the chlorophyll fluorescence induction effect. The network operates on the ZigBee protocol stack (IEEE 802.15.4 standard) in the 2.4 GHz frequency band. WSN includes low-power wireless nodes with adjustable transmission power (0 to -5 dBm) and receiver sensitivity of -95 dBm. The nodes are based on the wireless microcontroller NXP JN5168 with a 32-bit RISC processor. The system supports up to 100 wireless sensors in a single network and includes one coordinator and four sensor nodes. Each sensor has its own unique MAC address. Field Experiment. A full-scale field experiment was conducted in a cherry orchard to test the performance of the WSN under real-world conditions. The experiment consisted of five stages, with sensor clusters deployed at various distances and configurations. The testing procedure included equipment checks, sensor placement, measurement parameter configuration, and validation of data transmission. Testing Procedure.1. Preparation. Powering on the coordinator and sensors. Battery level check. 2. Measurement. Placing sensors on tree leaves. Measuring sensor height and distance to coordinator. Ensuring all sensors are connected. Setting CFI measurement parameters. Starting data collection. Verifying data storage and transmission. To evaluate the quality of communication depending on the distance between the sensors (identified as AD, F9, E3, FA) and the coordinator, testing was conducted in clusters at various distances over five stages. Stage 1. Sensors: AD, F9. Distance to coordinator: 20 m. Sensor height: 2 m. Sensor spacing: 2 m. Self-organization time: 6 s. Measurement duration: 4 minutes. Stage 2. Sensors: AD, F9. Distance: 60 m. Sensor height: 1.5 m. Sensor spacing: 1 m.Self-organization time: 6.8 s. Measurement duration: 4 minutes. Stage 3. Sensors: AD, F9. Distance: 40 m. Sensor height: 1.5 m. Sensor spacing: 2 m. Self-organization time: 6.75 s. Measurement duration: 4 minutes. Stage 4. Sensors: AD, F9, E3. Distance: 30 m. Sensor height: 2 m. Sensor spacing: 3 m. Self-organization time: 6 s. Measurement duration: 4 minutes. Stage 5. Sensors: AD, F9, E3, FA. Distance: 30 m. Sensor height: 2 m. Sensor spacing: 3 m. Self-organization time: 6 s. Measurement duration: 4 minutes. Environmental Parameters Recorded: Air temperature, Air humidity, Wind speed (based on meteorological data) Total Measurements: 91 measurements were collected from all wireless sensor nodes during the five test stages.
