Pololu Distance Sensor with Pulse Width Output, 130cm Max

Pololu Distance Sensor with Pulse Width Output, 130cm Max

Dieser kleine Lidar-basierte Abstandssensor meldet die Entfernung von Objekten bis zu einer Entfernung von ca. 130 cm (50?) mit einem gepulsten Signal, ähnlich einem Hobby-Servo-Steuersignal. Ein digitaler Mikrocontroller-Pin kann zur Zeitmessung der Länge jedes hohen Pulses verwendet werden, der die gemessene Entfernung kodiert. Der Sensor arbeitet über einen Eingangsspannungsbereich von 3,0 V bis 5,5 V, und der 0,1?-Pin-Abstand macht die Verwendung mit Standard-Lötfreien Breadboards und 0,1?-Perfboards einfach.Hinweis: Die maximale Reichweite von 130 cm ist nur für hochreflektierende Objekte bei guten Umgebungsbedingungen erreichbar. Ziele mit geringerem Reflexionsvermögen oder schlechte Umgebungsbedingungen verringern die maximale Reichweite.

Overview

This compact sensor makes it possible to measure the distance of objects up to about 130 cm away using a simple digital pulse width interface. It uses a short-range lidar module to precisely measure how long it takes for emitted pulses of infrared, eye-safe laser light to reach the nearest object and be reflected back, allowing for 1 mm resolution.

As long as the sensor is enabled, it takes continuous distance measurements and encodes the ranges as the widths of high pulses, which can then be timed by a microcontroller using a single digital input.

Specifications

Operating voltage: 3.0 V to 5.5 V
Current consumption: 30 mA (typical) when enabled, 0.4 mA when disabled
Maximum range: approximately 130 cm (for high-reflectivity targets in good ambient conditions; lower-reflectivity targets or poor ambient conditions will reduce the maximum detection range)
Minimum range: 4 cm (for accurate measurement); < 1 mm (for detection)
Update rate: 100 Hz to 110 Hz (10 ms to 9 ms period)
Field of view (FOV): 15° typical; can vary with object reflectance and ambient conditions
Output type: digital pulse width
Dimensions: 21.6 × 8.9 × 3.5 mm
Weight: 0.4 g

General specifications

Resolution:1 mm
Maximum range:130 cm 1
Sampling rate:100 Hz 2

Notes:

This maximum is only achievable for high-reflectance objects in good ambient conditions; lower-reflectivity targets or poor ambient conditions will reduce the maximum range.
Minimum.
Typical average current draw when enabled; disabling via the EN pin reduces it to around 0.4 mA.
