SKU: SEN-000216-915


LDS02 is powered by 2 x AAA batteries and built for long time use. These two batteries can provide about 16,000 ~ 70,000 uplink packets. After the battery runs out, users can easily open the enclosure and replace with 2 common AAA batteries.

The LDS02 will periodically send data every day every time the door is opened or closed. It also counts the amount of times the door opens and calculates the duration of the last time the door was opened. User can disable the uplink for each open/close event, instead, device can count each open event and uplink periodically.

LDS02 has the open alarm feature, meaning user can set the device to send an alarm if the door has been open for a certain time.
