Product Overview
805 is a product model specifically designed for large-scale grazing tracking of cattle and sheep in the Red General series. It is a core product in the LoRa livestock series of Jinshengchang’s hardware product line. The main forms include the 805A LoRa ear tag (directly worn on the livestock’s ear) and the rechargeable neck-mounted tracker. Through LoRa low-power wide-area network + GPS/BeiDou dual-mode positioning, long-term maintenance-free tracking of livestock location is achieved.

Product Features

1. Lightweight wearing design
   With a weight of 58g (ear tag type), it is over 40% lighter than similar products on the market, reducing the burden on livestock ears without affecting their feeding and activities. The neck-hanging type weighs only 120g, suitable for large livestock such as cattle.
2. LoRa wide-coverage communication
   The communication distance remains stable at 3-5 km (depending on the terrain), with one base station capable of covering a large area of pasture. It does not rely on cellular networks, and can still report data in remote areas without signal coverage.
3. Rechargeable + Long battery life
   The 1500mAh rechargeable battery can last for several months with a reporting frequency of once per hour. It can be charged through a dedicated base or magnetic cable, and supports batch charging management.
4. All-weather adaptability
   With waterproof design and an engineering plastic casing, it is resistant to sunlight, rain, and dust, making it suitable for harsh outdoor environments. Its operating temperature range covers -20℃ to 60℃, meeting the climatic conditions of most pastoral areas.
5. Multi-dimensional data collection
   Not only is it a locator, but it also serves as a livestock health monitoring terminal – simultaneously collecting three-dimensional data on location, body temperature, and activity level, providing a data foundation for smart animal husbandry.

Are there any specific areas that you need further understanding? For example, the reporting data format of the LoRa protocol layer, the reading logic of temperature/activity sensors, or the API details for interfacing with the lora8 platform.
