Netvox’s wireless three-axis digital accelerometer alerts to changes in the motion, orientation and vibration of rotating machinery, allowing faults to be detected early before the equipment fails. The alert signal is sent via the LoRaWAN protocol at pre-set intervals throughout the day.

Features

• Wireless range of up to 10 km (depending on environment)
• LoRaWAN Class A compatible
• Frequency Hopping Spread Spectrum (FHSS)
• Improved interference immunity
• Improved power management for longer battery life
• Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
• Battery Life of up to 5 years (determined by sensor reporting frequency and other variables)
• Over-the-air updates (future)
• Third-Party online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email (optional)
