This rumen bolus sensor, based on LoRaWAN, is designed to collect cows’ activity, rumen temperature, and movement. The bolus material is environmentally friendly and harmless to the animal.
After insertion, the rumen bolus will automatically transmit data to LoRa base stations and cloud-based platforms, allowing users to access this information at any time, from anywhere.

The water meter measurement data and the remaining battery capacity are automatically uploaded to the server platform and displayed regularly.
