Wireless grain temperature monitoring system for silos


Wireless, autonomous system – a quick and convenient solution for grain silos.


  • Comfort – Simple installation. Data is transmitted wirelessly. You will avoid laying wires, digging trenches, building switch cabinets.
  • Economy – The device is charged by using solar energy. Can work safely for up to 6 months if not charged.
  • Precision – Sensors are installed in the cable every 1.5m by default. Sensor accuracy 0.5°, measuring step 0.25°.
  • Speed – Message is sent instantly whenever temperature reaches critical limit. It is enough to have a mobile phone with you.
