EVISION Obstacle Detector
MS 1528
Obstacle Detector is a distance-measuring system based on ultrasonic sound utilizing the LPC2364FBD100. The system transmits a burst of ultrasonic sound waves towards the subject and then receives the corresponding echo. The LPC2364FBD100 integrated analog comparator is used to detect the arrival of the echo to the system. The time taken for the ultrasonic burst to travel the distance from the system to the subject and back to the system is accurately measured by the LPC2364FBD100. Assuming the speed of sound in air at room temperature to be 1100 ft/s, the LPC2364FBD100 computes the distance between the system and the subject and gives the information to buzzer. The minimum distance that this system can measure is eight inches and is limited by the transmitter’s transducer settling-time. The maximum distance that can be measured is 2 meter. The amplitude of the echo depends on the reflecting material, shape, and size. Sound-absorbing targets such as carpets and reflecting surfaces less than two square feet in area reflect poorly. The maximum measurable range is lower for such subjects. If the amplitude of the echo received by the system is so low that it is not detectable by the Comparator. This system is mainly used to replace normal sticks for the visually impaired (blind) peoples. This unit has standard USB 2.0 for mobile interface and has android application for user interface

Ultrasonic Leak Detector
ULD-420
When equipment begins to fail due to an air or gas leak or vibration, or electrical discharge, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD-420 Ultrasonic Leak Detector converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure. When working in unpressurized systems or the pressure is not sufficient enough to detect or verify a leak with the Receiver alone use the Transmitter.

Power Line Meter
The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

SparkFun ToF Range Finder Breakout for VL6180
12784
This is the SparkFun "Time-of-Flight" Range Finder, a breakout for the VL6180 distance sensor. Unlike most distance sensors that rely 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.
