Leaf Sensor Rev3

New Improved - Calibrated real-time leaf sensor that measures water levels of live plants for aeroponics, hydroponics and drip irrigation systems. 

Easy to Use: Simply affix the Leaf Sensor to a healthy plant leaf and begin monitoring the indirect measurement of leaf turgidity (moisture level) using a standard 4-digit display multimeter and external battery (not included).

Applications (partial list):  Plant Sciences / Irrigation Control / Water Management / Weather Stations / Research / Education /Agronomy Consultants

Benefits:  Measure leaf moisture levels (leaf thickness) and sap flow in real time - know when to water!

  How to use  

Affixed sensor to a  leaf.  Leaf sensor signal readings (volts) are taken with a digital multimeter or a data  logger device.  As the voltage measurement increases the plant's need for water increases.  Watering lowers the signal reading to a steady state (water not needed).
