Pololu Digital Distance Sensors
We have several different versions of Pololu Digital Distance Sensors, all with the same dimensions and pinout:
Output type | Sensor | Maximum range |
Minimum update rate |
Jumper settings (4321) |
---|---|---|---|---|
digital (does not provide distance measurement) |
#4050: Digital output, 5cm | 5 cm | 145 Hz | 0000 |
#4052: Digital output, 10cm | 10 cm | 115 Hz | 0010 | |
#4054: Digital output, 15cm | 15 cm | 95 Hz | 0100 | |
pulse width (provides distance measurement) |
#4064: Pulse width output, 50cm max | 50 cm | 50 Hz | 1110 |
These are the output graphs for the three digital output versions (items #4050, #4052, and #4054) that just report if an object is in their detection range:

The output graph is a bit different for the version that uses a pulse width to encode the measured distance (item #4064). The output for this version is similar to hobby servo control signals and is shown below as a function of time:

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.

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.

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.

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.
