Know where every animal is, how it’s moving, and whether it’s healthy — all from your phone. Our cattle ear tags combine GPS positioning, RFID identification, and real-time health monitoring in a single 14g device. Each tag continuously measures activity, body temperature (±0.1°C), and location, transmitting data every 20 minutes via a BLE smart gateway to a cloud platform you can access anywhere. The system auto-completes a full herd headcount in seconds, flags animals with fever or lameness before visible symptoms appear, and detects estrus activity spikes for precisely timed AI breeding. With a 3-year battery and IP67 waterproof construction, these tags work reliably across extensive pastures, dairy barns, and feedlot environments.

What Are GPS & RFID Cattle Ear Tags?
GPS and RFID cattle ear tags are precision livestock monitoring devices that replace visual observation with continuous digital data. The system has three parts: a lightweight ear tag worn by each animal, a network of BLE smart gateways installed around the property, and a cloud platform accessible from any device. Each tag records activity levels via a 3D accelerometer, core body temperature via a precision thermistor, and zone location via gateway proximity — transmitting readings every 20 minutes. The platform processes this data to automate daily tasks: counting the herd in seconds, flagging a cow with a fever spike, or alerting you when an animal’s activity pattern indicates estrus. This technology helps dairy, beef, and sheep operations reduce labor, detect illness earlier, and make data-driven breeding decisions.
How It Works
Remote Access: Open the app or web dashboard to see all tagged animals on a map, run an automatic headcount, check individual health status, and review 7-day trends — from anywhere with internet.
Tag Application: The 14g ear tag is applied using a standard applicator, just like a visual ID tag. Each tag has a unique ID linked to that animal’s records.
Continuous Monitoring: Internal sensors measure activity (movement/steps), body temperature, and proximity to gateways every 20 minutes. The tag transmits via Bluetooth Low Energy to the nearest gateway.
Gateway Data Relay: Gateways positioned around the property receive signals from all tags within a 200-meter radius. Each gateway handles up to 1,000 tags and uploads aggregated data to the cloud via 4G.
Cloud Processing & Alerts: The platform analyzes incoming data against each animal’s individual baseline. When a cow spikes a fever, drops activity, or shows the characteristic movement surge of estrus, an instant alert is sent to your phone.
Application Scenarios
- Dairy Herds: Detect estrus automatically and time AI without visual observation. Monitor fresh cows for early signs of metritis or ketosis.
- Beef Cow-Calf Operations: Locate cows and calves across extensive brushy or hilly pastures. Receive alerts when a cow isolates herself — a key sign of calving.
- Sheep Flocks: Count sheep remotely across large paddocks. Detect predation events or fence breaches when animals suddenly scatter.
- Research & Breeding Programs: Track individual activity and temperature trends for nutritional, genetic, or welfare studies with continuous data.

GPS Ear Tags vs Traditional Herd Management
| Feature | Traditional Visual Monitoring | These GPS & RFID Cattle Ear Tags |
|---|---|---|
| Herd Headcount | Hours of manual counting, prone to error | Automatic in seconds, 100% accurate |
| Sick Animal Detection | Visual — often 1–2 days after onset | Temperature and activity alerts 24–48 hours before visible signs |

Common Questions
Cows in estrus show a characteristic spike in daily activity — often 2–3 times their normal movement. The system tracks each animal’s individual 7-day rolling average and sends a high-activity alert when a cow’s movement exceeds her own baseline significantly. This enables precisely timed AI breeding without relying on visual observation or expensive synchronization protocols.
Each tag has a 3-year battery life under normal operating conditions. The tags are sealed units and are not rechargeable. When the battery is depleted, the tag is simply replaced with a new one using a standard ear tag applicator — no special tools required.
A single gateway covers approximately a 200-meter radius in open terrain. Buildings, hills, and dense tree lines reduce effective range, so larger or more varied properties may need additional gateways for complete coverage. We provide a free network design consultation — share your property dimensions or a satellite map, and we’ll recommend the optimal number of gateways and their best placement.
Yes. At just 14g, the tag is lightweight enough for sheep and goats. The gateway network and cloud platform work identically across species. The system is suitable for all ages and breeds of cattle, sheep, and goats.
The gateway requires a 4G signal to upload data. If signal is weak at the proposed gateway location, we can explore using an external high-gain antenna or moving the gateway to a higher elevation such as a barn roof or hilltop. We recommend checking signal strength at planned gateway sites during the planning phase.
The system uses gateway proximity rather than power-hungry GPS chips on each tag. The platform shows which gateway the animal is nearest to, providing accurate zone-level location — for example, Cow #4587 is in the North Pasture near the water trough. This approach extends tag battery life to 3 years compared to satellite GPS tags that require frequent recharging.
