BLE5.0 high precision temperature sensor recorder. Beacon monitors the ambient temperature and uses Bluetooth radio to achieve 24-hour monitoring via mobile app or other Bluetooth-enabled products. There is no need to replace the battery within 3 to 5 years.
When used, it can be used with the corresponding positioner. One positioner can be used with 24 Beacons. By uploading all the data in the Beacon to the server through the locator, it is also possible to achieve precise localization of the local area.
EELINK Tracker Host + Beacons Schematic Diagram
EELINK Tracker Principle :
Device built in GPS module and communication module, it will send GPS and other related data packages to platform server by base station every 30 seconds (can be set remotely), Platform displays the location of device on a map based on the poisitioning data from satellite. Because 2G / 3G / 4G network is used to transmit data, tracker needs to be equipped with a SIM card which enabled data function. There are 2 communication channels between user and device.
- In channel 1, Browser or APP issues an instruction which transmitted to device from server through Internet.
- In channel 2, Mobile phone sends a SMS instruction to device directly, the instruction will reach device and be execute.
EELINK Beacon Principle :
Beacon has built – in temperature sensor and Bluetooth module that collects temperature data at certain intervals and broadcasts it via Bluetooth .
- In mode 1, data is transmitted to mobile phone APP through Bluetooth, and then send to server via internet.
- In mode 2, data is transmitted to the host device via Bluetooth and then uploaded to the server via the internet. One host tracker can connect to a maximum of 24 beacons.
EELINK GPS Tracker use GPS + LBS double positioning way . Under GPS positioning mode , the highest accuracy can reach 3-5 meters when signal is quite good ( 7 GPS satellites are found ) . In the case of general siginal , it’s 5 to 15 meters positioning accuracy . If no GPS signal , device will use LBS way to get an unaccurate position , Accuracy depends density of base stations .
When Beacon is used alone, it needs to cooperate with the mobile phone APP to obtain historical information of the device through the APP. The position is located by the RSSI signal strength.It should be used in logistics management, supply chain, warehouse, terminal and personal asset management. Beacon can store 4 days of data (one for 5 minutes), data content date and time + temperature + battery
