Pololu Digital Distance Sensor 10cm

This small lidar-based distance sensor detects the presence of objects within 10 cm. It has a single digital output that drives low when an object is being detected; otherwise, it is high. It 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.

Some example applications include:

• break-beam sensor or photogate alternative
• non-contact bumper or obstacle detector for a robot
• non-contact interface element for activating a device or process
• a counter or timer of objects as they pass by

Specifications:

• Operating voltage: 3.0 V to 5.5 V
• Current consumption: 30 mA (typical) when enabled, 0.4 mA when disabled
• Maximum range: 10 cm
• Minimum update rate: 115 Hz (8.7 ms period)
• Field of view (FOV): 15° typical; can vary with object reflectance and ambient conditions
• Output type: digital signal (low when detecting an object, high otherwise)
• Dimensions: 21.6 × 8.9 × 3.1 mm
• Weight: 0.4g
