MUUU! is a smart livestock collar with LoRa, GPS, and vital sign sensors to track each animal’s location and health.

🔍 How it works?

The livestock collar is designed to monitor the health and location of your animals in real time. It integrates multiple sensors to provide essential data:

1. 🛰️ GNNS module: Tracks the animal’s position, helping you locate them reliably even in open fields or challenging environments.
2. 🌡️ Body temperature sensor: Provides high-accuracy body temp measurements, enabling early detection of illness or heat stress.
3. 💧 Humidity sensor: Measures relative humidity, helping assess sweating and thermal comfort.
4. ❤️‍ Heart rate and SpO₂ sensor: Measures heart rate and blood oxygen saturation (SpO₂) providing key vital signs.

All collected data is processed by the MCU Wio-E5 by Seeed Studio , a low-power microcontroller that integrates a LoRa transceiver 📡 for long-range, low-energy data transmission. This enables efficient communication with gateways over several kilometers while preserving battery life, making it ideal for remote livestock monitoring.

🔋 The collar is powered by a 1 W solar panel and a LiPo 18650 battery, ensuring continuous operation even in low-sunlight conditions while maintaining low energy consumption for extended autonomy ⏳.
