For the G sensor, you can attach to equipment with magnet as below:
Make sure antenna is well installed before turn on the device.
When you get the device, it is off. Just press the button for 3 seconds and you can turn on the device. When you
turn on the device, there are 4 led on the top, all led will twinkle from left to right. If you turn off the device, press
the button for 3 seconds and all led will twinkle from right to left, after turn off the device, no data collecting and

uploading.
When turn on the device, normally the sensor will read data and upload every 10 mins, if you want to send data
immediately, you can just press the button for short time, less than 1 second, and sensor will read and upload
data. While press the button, 4 led will be green at the beginning, and then TX led on the device will be green
while sending data as below:
4 led on top of the device, and they are POWER/TX/RX and SENSOR from left to right as below. POWER is the
battery level, normally when you turn on the device, 4 led will be green which means the battery level is 100%. If
only 3 led are green which means the battery is 75% left. There is low battery alert and POWER will be red while
low battery level.
TX and RX means sensor is sending or receiving data.
2.2 Data uploading by press the button

Sensor is green means sensor is reading and uploading data, if sensor is red, that means sensor is not working,
please kindly check if the sensor is will connected.
There is one USB-C port as below, which is for power on and config, connect device to laptop with a USB-C cable,
and you can config the device, make sure to install USB driver and here is the link for driver: Serial Port Driver
When turn on the device, it will send data immediately, also you can press the button for 1 seconds, then the
device will also send data. Normally when you get the device from factory, the default uplink period is every 10
mins and check period is 10 seconds, and if you want to change the period, you can connect the device to
2.4 USB-C Port

And here is the data decoder for TTN platform, just copy the information as below:
function decodeUplink(input) {
var obj = {};
var warnings = [];
var len = input.bytes?input.bytes.length:0;
var offset = 0;
var dtype;
offset++;
/* Battery voltage level: Battery voltage is from 0-31, 31 means battery is 100% left. */
obj.battery = (input.bytes[offset++]&0x1F);
/* This field is reserved. Generally, the voltage value of the memory chip is 0.1V. For
example, the value of 33 is 3.3V */
obj.vol = (input.bytes[offset++]);
do {
dtype = input.bytes[offset++]; /* dtype: Sensor type */
if(0x01 == dtype){
