1 Effective range depends on object reflectivity and ambient lighting conditions.
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:

Products in category “Pololu Digital Distance Sensors”
Pololu item #: 4050 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 5 cm (2″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4052 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 10 cm (4″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4054 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence objects within 15 cm (6″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4066 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 25 cm (10″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4067 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 50 cm (20″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4069 | |

Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 100 cm (39″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4077 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
This small lidar-based distance sensor detects the presence of objects within 200 cm (79″). 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 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Pololu item #: 4064 | |
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 #: 4071 | |
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. 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 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.
Pololu item #: 4079 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
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. 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 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.
