VPD Chart

The app calculates VPD using air temperature, relative humidity, and canopy temperature. View real-time VPD values on an interactive chart. Connect sensors for automated readings or manually input data via intuitive sliders and text inputs.

Key features:
• Interactive VPD chart with manual input
• Default crop types
• Organize charts by assigning them to different zones
• Display spots that share the same VPD value
• Zoom in and out of the VPD chart with a two-finger pinch and drag to pan around
• VPD Target - long-press the chart to set a target VPD value
• Dew point area visualization
• Grow Timeline
• Sync sensor historical data by importing it from sensor's app, or via cloud APIs
• Explore sensor history by panning and zooming
