Product description: Digital distance sensor 200 cm - Pololu 4077
Pololu brand module withdistance sensorbased onLidartechnology. The sensor has an operating range ofup to 200cm and is poweredfrom 3 V to 5.5 V. It is equipped with one digital output which changes its state to low when an object is detected. Itis not capable of measuring distances, it only reports the detection of an obstacle within 200 cm with an accuracy of1 mm. This sensor uses a short-range Lidar module toaccurately measurethe time it takes for the emitted pulses of eye-safe infrared light to reach the nearest object and be reflected back.
Application example
- Alternative brake light sensor and photobeam
- Non-contact sensor for robot collision or obstacle
- A non-contact interface element to activate a device or process
- Counter or timer for objects as they pass by
Infrared light emitted by the sensor, recorded with a camera without IR filter.

Using the distance sensor
The board has 3 leads:VIN, GND and OUT.Pins are located on the board in the form of holes with a 2.54 mm pitch, with the possibility of solderinggoldpin connectors(not included). VIN pin should be provided with voltage from3V to 5.5V, GND is system ground pin (0V). OUT pin triggers low state (0 V) when an object is detected and high state (up to VIN level) when an object is not detected. TheredLEDalso lights up when an object is detected. The board also features an ENABLE pin that can be set low to put it into a low power state, which consumes about 0.4 mA of current. The ENABLE pin is pulled up to VIN by default.
There is a protective film on the sensor that must be removed before working with the module.
Jumper settings on the sensor module
The module is equipped with four surface mount configuration jumpers (4321) that define its operating modes. Various versions of Pololu sensors have jumpers set appropriately in the form of 0 Ω resistors. The resistors can be soldered out or bridges can be added to convert one version of the sensor to another. This sensor can be converted to any other version of irs17a according to the table below.

Comparison of Pololu and Sharp sensors.
Comparison with Sharp sensor
The Pololu distance sensor modules have the sameshape and leadsas theSharpsensors. They are available in the same and larger sensing ranges. This means that they can be usedinterchangeably. The sensors in the newer Pololu devices aremuch thinnerthan the Sharp modules, so the zero point is about 7mm closer to the board and the beam angle is wider in the newer devices.
Pololu distance sensor specifications
