Smart pH Rumen Bolus

  • LoRaWAN Compliant
  • Communication range up to 500Meters
  • Battery life up to 2 years
  • Real-time Monitoring of the rumen temperature, rumen pH, movement and activity
  • IP68 Rugged Housing,food grade material, compact size 103.58*28mm
  • Duration of pH measurement: 180days after installation.


JS0140 rumen bolus is designed to capture cattle activity, rumen temperature, rumen pH, and movement. The material of the bolus is eco-friendly and causes no harm to the animal. Once inserted into a cattle, the bolus will remain in the rumen, All data is transmitted automatically first to the LoRa Base Station and then to a cloud-based platform, which allows farmers, vets, and scientists to process the information and deal with unexpected issues anytime, anywhere. The earlier you detect health problems, the earlier you can react and reduce severe courses of diseases on your farm. Allow farmers to maximize the efficiency of farms.
