Soil Moisture Sensor

 

Soil Moisture Sensor

Agriculture is practiced like art in Pakistan. Farmers take all the key decisions -from crop selection to its harvest- based on their experience and gut feel. As a result, we have low crop yields, high input costs, and a dearth of modern management in the agriculture sector.

In an effort to change agriculture into science, WIT has played its part by introducing “Soil Moisture Sensor”. This smart device assists farmers in making informed irrigation decisions, allowing them to achieve increased crop yield at reduced irrigation cycles, thus boosting not only boosting profits but also conserving water.

 

Features
  • Soil Moisture Sensing
    • That generates automatic alerts as to when to irrigate and when not to, thus conserving water and boosting yield.
  • Telemetry
    • GSM and LoRa based telemetry that allows network of sensors over a vast area be monitored by a mobile app.
  • Weather Proof Enclosure
    • IP67 rated enclosure that protects from water and dust ingress thus allowing care free application in all weather conditions.
  • Long Battery Life
    • Coupled with efficient power management, there is enough juice inside to ensure yearlong operation without human intervention
