About this product

Description

Infrared range finder 20cm (~8") to 150cm (~60")
Analog interface
United with PSD
Lead free, ROHS compliant

Read the distance of the object in front of your robot. The Sharp GP2Y0A02YK0F IR Range Sensor - 20 cm to 150 cm takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 20cm (~8") to 150cm (~60"). The interface is 3-wire with power, ground and the output voltage and requires a SIRC-01 Sharp GP2 IR Sensor Cable - 8" .

It is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.

We also carry mouting brackets (perpendicularparallel  and multi-optiondesigned specifically for this sensor. The pictures below show these brackets being used with a shorter-range version of this sensor, which has the same width and height but a shorter depth:

Sharp has always made a great sensor.

Review by DJD Labs
General

I have used Sharp IR range finders all the way back to the 90's They have always been a great reliable sensor. They are often used in commercial and production level robots. You have to understand the nature of how it works, to understand its limitations.

It is simply sending out an IR blast than looks for a return, of any level, to gather how far the object is based on the amount of returned light.

So the surface, shape, and size, of the object can change the results you get from the sensor. So like with any object tracking of this nature it is best to take the average of multiple sensors, and or multiple samples of a single sensor to get a better overall average, and remove anomalies. NOTE: These sensors work great in groups and do not interfere with each-other.

With that said, the consistency across the sensors I have ordered over the years has always been the same, the notes mentioned above, are known, and apply to all sensors equally, so knowing this, you can allow for it in your application. For known variability is much better than pure random.

For the most recent install, I picked up 8 of these for a leg detection system, and at 4-7 Feet I found this sensor was able to get reliable data that was very usable. For people may not often think of these as good 'human' detectors, but they have a very fast response, limited beam width and fast 'resets' Unlike other sensors like PIR, and SONAR.

One tip I will give is get the harness, you will thank me later, when you try to source the proper connector and wire combination. The one available here by the Robot shop, is a perfect mate.

I would recommend this sensor to those who have it in mind. You can not beat the price, even for just a test prototype.

Be aware the limitations

Review by Sungjune
General

This type of sensors from Sharp shares two issues:

One is that their output is noisy, not quite random but occasional jump style noise. Median averaging can be helpful in this case but it limits the maximum bandwidth of the sensor.

Second issue is more tricky. When the object is out of range, i.e. too near or too far then it produces unexpected value. For example object at 2m (out of range) produces the same output as object 1m (in range).

When it comes to environmental effect, i.e. surface condition of the object or effect of day light, etc., it is more robust than other type of sensors such as ultrasonic type.

Better but more expensive than sonic rangers

Review by Douglas
General

It does what it says and I like that there are several versions for different distance ranges. The analog output is easier to deal with than reading a pulse width on a sonic ranger type sensor. Also, and this never occured to me beforehand but sonic rangers have a hard time dealing with clothing so if its peeps your ranging then infrared is the choice. OTOH since its analog you need some kind of interface for a raspberry pi.
