19 The Dragino LDS02 is a (% style="color:#037691" %)**LoRaWAN Door Sensor**(%%). It detects door open/close status and uplink to IoT server via LoRaWAN network. user can see the door status, open time, open counts in the IoT Server.
20
21 LDS02 is powered by (% style="color:#037691" %)**2 x AAA batteries**(%%) and target for long time use, these two batteries can provide about 16,000 ~~ 70,000 uplink packets. After battery running out, user can easily open the enclosure and replace with 2 common AAA batteries.
22
23 The LDS02 will send periodically data every day as well as for each door open/close action. It also (% style="color:#037691" %)**counts the door open times**(%%) and (% style="color:#037691" %)**calculate last door open duration**(%%). User can also disable the uplink for each open/close event, instead, device can count each open event and uplink periodically.
24
25 LDS02 has the (% style="color:#037691" %)**open alarm feature**(%%), user can set this feature so device will send Alarm if the door has been open for a certain time.
26
27 Each LDS02 is (% style="color:#037691" %)**pre-load with a set of unique keys**(%%) for LoRaWAN registration, register these keys to LoRaWAN server and it will auto connect after power on.
