Smart Ear Tags for Cattle.
Temperature & RFID Monitoring.
Commercial smart ear tags engineered for dairy farms, feedlots, and large-scale livestock operations. Continuously monitor body temperature trends, detect abnormal fever patterns, capture activity data, and identify individual animals through ISO-compliant HDX RFID for automated herd management.
Why Commercial Farms Choose Smart Ear Tags for Cattle
NexAgri-Sense combines continuous temperature monitoring, RFID identification, activity data, and lightweight hardware for commercial herd health and automation.
Continuous Temperature Monitoring
Continuous thermal trend monitoring across a 0°C–60°C measurement window with ±0.5℃ sensor accuracy. Detect abnormal temperature changes and potential fever patterns before obvious clinical symptoms appear.
RFID Identification & Automated Sorting
ISO 11784/11785-compliant HDX RFID enables automatic animal identification at drafting gates, parlor entry points, and compatible feed management systems while preserving individual animal records.
Lightweight Smart Ear Tag Design
Commercial models start at just 8g, with optimized ear-pin geometry and ruggedized enclosures designed for long-term livestock deployment and reduced ear strain.
Smart Ear Tag Series for Cattle Health & Tracking
Select the smart ear tag architecture engineered for barn-raised cattle, free-range livestock, or pasture tracking environments.

Smart Ear Tag Engineering & Temperature Monitoring
Industrial ear tag hardware engineered for continuous temperature trend monitoring, animal identification, activity sensing, and long-term commercial livestock deployment.
Smart Ear Tag Integration with Dairy Automation Systems
NexAgri-Sense combines animal identification with health and activity data so existing farm automation systems can identify individual cattle and trigger the appropriate management workflow.

Smart Ear Tag TCO & ROI for Commercial Dairy Farms
Evaluate the financial value of earlier temperature alerts, automated animal identification, and integration with commercial dairy workflows before hardware procurement.
1. Disease Early Detection & Intervention
Late disease detection can increase veterinary costs, treatment requirements, and involuntary culling risk in commercial dairy herds.
NexAgri-Sense continuously evaluates relative temperature trends and can flag abnormal fever patterns up to 48 hours before obvious physical symptoms appear, giving farm teams additional time for veterinary assessment and intervention.
2. Automated Animal Identification & Sorting
HDX RFID identification allows compatible sorting gates, parlor readers, and feed management systems to identify individual animals without manual visual verification.
Automated drafting can reduce repetitive handling tasks and connect animal identity directly with health, feeding, and herd management records.
3. Health Data & Herd Management Integration
Temperature, activity, and identification data can be connected to farm management platforms through the NexAgri software layer, allowing health alerts and animal events to become part of routine herd workflows.

NexAgri-Sense Smart Ear Tag FAQs
Practical selection and deployment answers for cattle temperature monitoring, RFID identification, activity data and livestock connectivity projects.
What does a NexAgri-Sense smart ear tag monitor?
NexAgri-Sense configurations combine animal identification with selected sensing and communication functions. Depending on the model, they can provide temperature-trend data, activity or step data, HDX RFID identity, location-related data, and telemetry for farm-management workflows.
Which smart ear tag configuration suits my farm?
For barn-raised cattle, BLE models such as S316 and S333 support temperature monitoring or RFID-led management. For free-range deployments, select NB-IoT or LoRaWAN models according to network coverage; the 4G solar configuration is intended for pasture tracking where GPS/AGPS, Wi-Fi/LBS and motion data are required.
How accurate is cattle temperature monitoring?
The S316 specification shown on this page lists a ±0.5℃ thermal probe accuracy within a 0℃–60℃ measurement window. Use the data to assess temperature trends and set farm alert rules; interpretation and follow-up should remain part of the farm’s animal-health process.
Can a smart ear tag diagnose a health condition?
No. The tag provides monitoring data and can flag temperature or activity changes that merit attention. It does not replace animal examination, veterinary judgement or the farm’s established treatment protocol.
Can the ear tag work with RFID readers and sorting equipment?
Yes, the S333-P-B configuration shown includes ISO 11784 / ISO 11785 HDX RFID. It can be used with compatible panel readers at milking-parlor entrances, sorting gates or automated feeders, subject to confirmation of the reader protocol and installation layout.
Do all NexAgri-Sense ear tags provide GPS tracking?
No. GPS/AGPS positioning is listed for the NexAgri 4G Solar ear tag configuration. Other models focus on BLE, LoRaWAN or NB-IoT connectivity with temperature, activity or RFID functions. Select the model around the monitoring objective rather than assuming GPS is included on every tag.
What battery life and enclosure options are available?
The product matrix lists approximately 18 to 48 months across battery-powered models, depending on the model and reporting architecture. The S316 is listed at IP68, while several other configurations are IP67; the 4G solar model is listed as IP65. Final endurance depends on communication settings and operating conditions.
What information is needed for a smart ear tag quotation?
Share animal type and herd size, housing or pasture conditions, target function such as temperature monitoring, RFID or tracking, available network coverage, reader or gateway requirements, and destination country. NexAgri can then recommend a NexAgri-Sense configuration and prepare the appropriate project quotation.
