1.1	22
39.6	23
80.3	24	The Dragino LDS12-LB is a (% style="color:blue" %)LoRaWAN LiDAR ToF (Time of Flight) Distance Sensor(%%) for Internet of Things solution. It is capable to measure the distance to an object as close as 10 centimeters (+/- 5cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)!. The LiDAR probe uses laser induction technology for distance measurement.
1.1	25
80.3	26	The LDS12-LB can be applied to scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, etc.
1.1	27
80.2	28	It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.
1.1	29
80.3	30	The LoRa wireless technology used in LDS12-LB allows 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.
62.4	31
80.3	32	LDS12-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.
1.1	33
80.3	34	LDS12-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
1.1	35
80.3	36	Each LDS12-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

	297
	298
	299	Example:
	300
	301	If the data you get from the register is 0x0B 0xEA, the distance between the sensor and the measured object is 0BEA(H) = 3050 (D)/10 = 305cm.

When the distance measurement gear is fixed, the farther the distance measurement is, the lower the signal strength; the lower the target reflectivity, the lower the signal strength. When Strength is greater than 100 and not equal to 65535, the measured value of Dist is considered credible.

To be specific, the product emits modulation wave of near infrared ray on a periodic basis, which will be reflected after contacting object.
