Distance Sensor with Pulse Width Output, 300cm Max

This small lidar-based distance sensor reports the distance of objects up to about 300 cm away with a pulsed signal similar to a hobby servo control signal. A digital microcontroller pin can be used to time the length of each high pulse, which encodes the measured distance. The sensor works over an input voltage range of 3.0 V to 5.5 V, and the 2.54mm pin spacing makes it easy to use with standard solderless breadboards and 2.54mm perfboards.

Note: The maximum range of 300 cm is only achievable for high-reflectance objects in good ambient conditions. Lower-reflectivity targets or poor ambient conditions will reduce the maximum range.

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 300 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

Important note: This product might ship with a protective liner covering the sensor IC. The liner must be removed for proper sensing performance.
