DFRobot Gravity Digital Adjustable Infrared Proximity Sensor. It has an adjustable detection range, 3cm – 80cm.  It is small, easy to use, assemble, and inexpensive.

Useful for robotics, interactive media, industrial assembly line, etc. The infrared wavelength is part of the Sun’s natural light spectrum. While is a nice fit for indoor projects, outdoors with plenty of sunlight and reflective surfaces on its sight is not advised. It’s incredibly repurposable and can be used for a lot of different projects. The adjustable screw on its back makes it very convenient for different purposes. After digital read shows on your Arduino pin and then you are ready to go. It is a great sensor choice for quick prototyping.

Use it on a robot for wall detection and wall follower, or as some of the projects listed below as a trigger system. Its round shape with the screwable holders makes it a good choice for a homemade assembled robot, with a hole of its diameter and the holders you can place it aiming at different positions on a robot. Or even place it near your PC to turn on and off your monitor.

To ease the difficulty,  a Gravity Interface is adapted to allow plug & play.  The IO expansion shield is the best match for this sound senor connecting to your Arduino.

Features :

• Red LED checks the state of the proximity sensor
• High repeated positioning accuracy
• High switching frequency
• Wide voltage range

DFrobot offers an advanced level of sensors at an affordable cost than any other competitor brand in the market, making them ideal for the one who wants to start some Projects through Different types of sensors.

After finding Different types of sensors on market, we at robu.in have determined that DFrobot is one of the good brands that offer a wide range of sensors at an Appropriate price.

This is an Arduino compatible sound level meter(also known as a decibel meter, noise meter). It uses an instrument circuit and low noise microphone, which enable it to accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such as highway noise monitoring stations, bedroom noise monitoring, etc.

Nowadays, there are many kinds of sounds surrounding, some of which are really noisy. It is really essential to measure whether the sound is noisy enough to do damage to our health.

The sound level meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. We have launched a sound level meter, which is compatible with Arduino, plug-and-play. It can accurately measure the sound level of the surrounding environment. This product uses an instrument circuit, low noise microphone, which makes it highly precise. It supports 3.3~5.0V wide input voltage, 0.6~2.6V voltage output. The decibel value is linear with the output voltage, which leads to a simple conversion, without a complex algorithm. The connector is plug-and-play, without welding, so this product can be easily used in your application.

The 103SR13A-1 is an unipolar hall-effect digital Position Sensor with 15/32-32 UNS-2A cylindrical aluminium threaded housing and 152mm (6-inch) 24-gauge stranded lead wires, irradiated polyethylene insulated termination. Meet NEMA 3, 3R, 3S, 4, 4X (stainless-steel housing), 12 and 13 requirements. They respond to the magnetic field from permanent magnets or electromagnets. This rugged non-contact sensing product use versatile, reliable Hall-effect sensor ICs that are operated by a magnetic field and are designed to respond to alternating North and South Poles or to South Pole only. The hall-effect position sensor includes latching and linear magnetic types. The standard open-collector sinking output (digital devices) or push-pull output (linear device) of the hall-effect position sensor can be easily interfaced with common electronic circuitry such as microprocessors, integrated logic, discrete transistors, and SCRs with compatible voltage specifications.
