SparkFun ToF Range Finder Sensor for VL6180
12785
This is the SparkFun "Time-of-Flight" Range Finder, a sensor board for the VL6180 distance sensor. Unlike most distance sensors that rely on reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it's the same means cellphones use to detect when the caller is holding their phone to their ear.

Relay Buddy PRO Test Kit
191
Relay Buddy is a quick go / no-go tester for the most common automotive relays. With the included adapters, Relay Buddy now tests 5 different relay types and also tests shielded relays. Relay Buddy provides you with an indication of the general health and functioning of the relay switch contacts and coil. It will check the control side of the relay by applying a signal to the relay coil while it checks for proper functioning of the relay contacts. Relay Buddy operates the relay several times during each test session as it watches for consistency in every cycle. Relay Buddy will fail the relay and light the RED LED if any one of the cycles proves unsuccessful during the test session.

Silicon Detectors
Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy th...show more -

Fiber Inspection and Cleaning
Dust - just because you can't see it doesn't mean it's not there. A 1-micrometer dust particle on a single-mode core can block up to 1% of the light (a 0.05dB loss). The only way to know it's clean is to inspect it before you connect it. And if it's dirty, it needs to be cleaned with the right tools or you might just make it worse. Know it's clean with our cleaning and inspection tools.
