摘要: Zero power wireless sensors, devices, and systems are used for crop water content monitoring. The sensors onsume no while monitoring the presence of dry conditions. Infrared reflectance from plants is measured when selected spectral conditions met, a circuit closed, activating an alarm, RFID tag, or radio transmitter. deployed consume monitoring, reducing eliminating need to change batteries.
