  1. Introduction to VPD and Its Significance Recently, I came across a company promoting a new RH and temperature sensor with AI-powered data analytics. The comments section sparked a lively discussion, with many questions raised about VPD measurements, the impact of radiation, and the importance of sensor shielding and ventilation. While these are valid concerns, I believe a key aspect is often overlooked. Current AgriTech innovations frequently prioritize combining sensors with AI models, potentially neglecting the fundamental biophysical principles and the limitations of the sensors themselves. Furthermore, relying solely on AI in data-limited fields like agriculture may not always be the most effective approach. Vapor Pressure Deficit (VPD) is a critical environmental factor that profoundly affects plant water status. Let's examine this concept more closely. While standard meteorological VPD provides a general estimate, the canopy-to-air vapor pressure deficit (Dc) more accura...

  Watering your crops doesn't have to be a guessing game. By using soil moisture sensors effectively, you can optimize irrigation, save water, and grow healthier plants. Here's how to get the most out of your sensors: 1. Master Your Tools: Read the manuals: Don't skip this step! The manuals will tell you how to use your sensors and software properly. Do your research:  Explore online resources and articles to learn advanced techniques and troubleshooting tips. 2. Install Like a Pro: Placement is key: Install sensors in areas that represent the average moisture level of your irrigation zone. Avoid air pockets: Ensure sensors are in good contact with the soil. Group similar plants:  Place sensors in fields with plants that have similar water needs. 3. Collect Data and Observe: Start with your current routine:  Continue your normal irrigation practices initially. Track moisture levels: Monitor soil moisture readings closely and observe how your plants are respondi...
