We released the first of our new Pololu distance sensors a few months ago, and now we’re releasing additional Pololu Digital Distance Sensors with longer ranges! These boards have the same form factor and pinout as both our old Sharp/Socle GP2Y0D8x carrier boards and the short-range Pololu distance sensors designed to replace those, but the new versions offer greatly increased detection and measurement ranges, opening up new possibilities in applications where longer-distance sensing capabilities are desired.

Like their shorter-range counterparts, these new Pololu distance sensors determine distance by using an integrated lidar module to measure the time of flight (ToF) of invisible, eye-safe infrared laser light. The new versions include four digital output versions, which simply indicate whether they detect an object within their respective range thresholds:
- Pololu Digital Distance Sensor 25cm
- Pololu Digital Distance Sensor 50cm
- Pololu Digital Distance Sensor 100cm
- Pololu Digital Distance Sensor 200cm
There are also two new versions with pulse width outputs, which encode a distance measurement in a pulsed signal:
- Pololu Distance Sensor with Pulse Width Output, 130cm Max
- Pololu Distance Sensor with Pulse Width Output, 300cm Max
(For more detail on how the different output types work, see the earlier announcement or the sensors’ product pages.)

This brings us up to ten different Pololu distance sensor options, as shown in these tables:
| Digital output (does not provide distance measurement) |

| #4069: Digital output, 100cm | 100Â cm | <Â 1Â mm | 100Â Hz | 0011 | |
| #4077: Digital output, 200cm | 200Â cm | <Â 1Â mm | 30Â Hz | 1011 | |
| Pulse width output (provides distance measurement) |

Jumper settings (4321) |
PCB ID |
|---|---|---|---|---|---|---|
| #4064: Pulse width output, 50cm max | ~50Â cm | 1Â cm | 3Â mm | 50Â Hz | 1110 | irs16a |
| #4071: Pulse width output, 130cm max | ~130Â cm | 4Â cm | 1Â mm | 100Â Hz | 0101 | irs17a |
| #4079: Pulse width output, 300cm max | ~300Â cm | 4Â cm | 2Â mm | 30Â Hz | 1101 | |
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 <Â 5Â mm for irs16a boards and <Â 1Â mm for irs17a boards.
We’ve also just published comprehensive information about all the possible jumper settings for these sensor boards on their respective product pages. By changing the jumper connections, you can make a sensor act like a different version or even select another configuration that isn’t available as a standard product. (And if you have a special volume requirement, we can manufacture a custom batch of sensors for you; please contact us for more information.)
Once again, we are offering an extra introductory special discount on these sensors, to help share in our celebration of releasing new products. The first hundred customers to use coupon code DISTSENSORS can get up to three units of each type (including the shorter-ranged versions released earlier) for just $9.95 each!
