The output graph is a bit different for the versions that uses a pulse width to encode the measured distance. The output for these versions is similar to hobby servo control signals and is shown below as a function of time:

| Brand: Pololu | supply outlook |
| Status: Active and Preferred | |

|
This small lidar-based distance sensor reports the distance of objects up to about 50 cm (20″) 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Note: The maximum range of 50 cm is only achievable for high-reflectance objects in good ambient conditions. Lower-reflectivity targets or poor ambient conditions will reduce the maximum range.
| Pololu item #: 5485 | |
| Brand: Pololu | supply outlook |
| Status: Active and Preferred | |
|

|
This small lidar-based distance sensor reports the distance of objects up to about 130 cm (50″) 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. It works over an input voltage range of 3.0 V to 5.5 V and features a side-entry 3-pin JST SH-style connector that is compatible with our 3-pin JST SH-style cables.
Note: The maximum range of 130 cm is only achievable for high-reflectance objects in good ambient conditions. Lower-reflectivity targets or poor ambient conditions will reduce the maximum range.

This small lidar-based distance sensor reports the distance of objects up to about 300 cm (120″) 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. It works over an input voltage range of 3.0 V to 5.5 V and features a side-entry 3-pin JST SH-style connector that is compatible with our 3-pin JST SH-style cables.
