The leading open global standard for secure, carrier-grade IoT LPWAN connectivity.
Laser Distance / Level Sensor for LoRaWAN® Outdoor remote monitoring. Generic ranging and proximity monitoring. Snow level monitoring. Water level monitoring. Flood monitoring. Presence detection.
DISTANCE
Range: 0 … 40 m
Resolution: 10 mm (single sample), 1 mm (average of N samples)
Accuracy:
< 2 m, ±50 mm, Nonlinearity is present below 1 m
≥ 2 m, ±1 % of distance or ±25 mm
Better accuracy is achieved by capturing N samples and
evaluating statistical data, e.g. the average of N samples.
The device DL-LID measures the distance between the sensor head and the target. The measurement principle is based on infrared laser pulses which are transmitted by the sensor and reflected back from the target object. Using the time of flight of the laser pulses and the known speed of light, the sensor computes the traveling distance and thus the distance to the target.
For each measurement, the device captures N distance readings (samples). By default, N = 10.1 From these N samples, a set of statistical values is computed: average distance, minimum, maximum, median, 10th, 25th, 75th, 90th percentiles and the most frequent value. These statistical values are transmitted, as well as the number of samples (N), the total acquisition time and the battery voltage. The knowledge of the statistics of the distance samples allows the user to estimate the distance with greater accuracy and to evaluate the quality and uncertainty of the measurement.
