The DS03A-LB allows the device to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The DS03A-LB will send periodic data every 2 hours for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/closed event, instead, DS03A-LB can count each open event and uplink periodically.
DS03A-LB supports the Datalog Feature, it can save the data when there is no LoRaWAN network and uplink when the network recovers.
DS03A-LB has the Open Alarm Feature, user can set this feature so the device will send an alarm if the door has been open for a certain time.
DS03A-LB is designed for outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures
DS03A-LB supports BLE configure and wireless OTA update which make users easy to use.
DS03A-LB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to 5 years.
Each DS03A-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.
