Alternate Wetting and Drying (AWD) is a water-saving technology that farmers can apply to reduce their irrigation water consumption in rice fields without decreasing its yield. In AWD, irrigation water is applied a few days after the disappearance of the ponded water. Hence, the paddy field gets alternately flooded and non-flooded. Smart AWD tube for paddy fields helps in conveniently implementing the AWD. It generates an alert when water reaches 15 cm below the soil surface, and then irrigation is applied to re-flood the field to a depth of about 5 cm. 

Smart AWD ensures reliable water level measurements without dependence on farmer's skills. Using Smart AWD, farmers can save up to 25% in irrigation costs without any yield penalty.

Features: 

• Up to 3-Point Water Level Sensing:
  Enables monitoring at up to three depth levels, generating timely alerts for farmers on when to irrigate rice fields.

• Telemetry:
  LoRa-powered telemetry allows multiple sensors across large fields to be monitored seamlessly through a mobile application.

• Weatherproof Enclosure:
  An IP67-rated enclosure protects the device from water and dust ingress, ensuring reliable and carefree operation in all weather conditions.

• Long Battery Life:
  Supported by efficient power management and high energy-density batteries, the system can operate for up to a year without requiring human intervention.
