Key feature and functions

MCU	Description
NRF52811	Bluetooth SoC

Sensor	Description
KXTJ3	3 Axis Accelerometer
Si7201	Hall Sensor
NTCG104BH103JT1	NTC Temperature Sensor
Battery	1/2 AA Battery 1200mAh

It is a motion tracker capable of BLE communication.

BLE communication is possible using NRF52811 SoC

It can be turned on and off using Si7201 Hall sensor and magnet.

The acceleration values are collected using the KXTJ3 sensor.

The temperature value is collected using NTC.

It operates for 5 years using a battery.

Cow Ear tags detection heat and disease

Sensors can be used to collect AI learning data to classify animal motions such as cows and sheep.

We used the sensor as the Ear Tag of the cow.

We have succeeded in learning Edge AI, which categorizes cow movements into rumination, feeding, rest, and high activities.

Based on the four motions classified using Edge AI, we succeeded in detecting six conditions, including heat and disease.
