  • Description
  • Specifications
  • This sensor takes continuous distance measurements as long as it is enabled, up to 120 in. (300 cm) away. It uses a simple digital pulse width interface (similar to a hobby servo control signal) which can then be timed by a microcontroller using a single digital microcontroller pin. Eye-safe laser light is emitted from a short-range lidar module to hit the nearest object and then be reflected back. The sensor measure the time it takes to receive the reflected light to gauge distance with a resolution of 2 mm.

    This sensor has three connections that are necessary for use: VIN, GND, and Out. The connections work with standard 0.1 in. Headers.

    • Connect the VIN to a 3V - 5.5V source
    • Connect GN to 0 volts
    • The sensor outputs digital pulses from the OUT pin.
    The board has an optional ENABLE pin that can be driven low to put it into a low-power state that consumes approximately 0.4 mA. This pin can be accessed through a via or its neighboring surface-mount pad on the back side labeled “EN”.

    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.
