Note 1: Effective range depends on object reflectivity and ambient lighting conditions.
Note 2: Objects closer than the minimum distance can still be detected, but the measured distance might be inaccurate. The minimum detection range is < 5 mm for irs16a boards and < 1 mm for irs17a boards.

These are the output graphs for some of the digital output versions that just report if an object is in their detection range:

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:

Pololu item #: 4064
Brand: Pololu supply outlook
Status: Active and Preferred 
RoHS 3 compliant
Out of stock.
Quantity:

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.

Quantity:

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.
