The working principle of an ultrasonic sensor is simple and use high-frequency sound waves that are evaluated when the sensor received back the waves. To determine the distance between the robot and object, the sensor measure the elapsed time between sending and receiving the waves. These sensors are ideal for measurement in different environments where measurements cannot be affected by the surface, material, light, dust, or other noises. In robotics, ultrasonic sensors are used in a wide range of applications including here the measurement of distance, presence detection, or detect the position of an object. HC-SR04 is one of the most popular ultrasonic sensors used in robotics by students and hobbyists to determine the distance from a robot to objects. It is available at a low-price, it is stable and has high accuracy. Working principle is similar to bats , and its operation is not affected by sunlight or other noises. HC-SR04 provides measurement function between 2 and 400 centimeters at a range accuracy of 3 millimeters. The HC-SR04 module hosts the ultrasonic transmitter, the receiver and control circuit.

Ultrasonic Distance Sensor with Ascii serial O/P is an amazing product that provides very short to long-range detection and ranging. The sensor provides precise,Stable non-contact distance measurements from about 2cm to 400 cm with very high accuracy. Its compact size, higher range and easy usability make it a handy sensor for distance measurement and mapping. The board can easily be interfaced to microcontrollers RX pin (USART). At every 50ms sensor transmits an ultrasonic burst and send out Ascii value of distance that corresponds to the time required for the burst echo to return to the sensor. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you’ll also find this product to be useful in security systems or as an infrared replacement if so desired. Since it is very stable ,the “ECHO” Ultrasonic sensor module can be used for Micro mouse application instead of IR sensor.

Specifications:

Professional EMI/RFI Complaint PCB Layout Design for Noise Reduction
Accurate and Stable range data
Data loss in Error zone eliminated
Modulation at 40 KHz
Mounting holes provided on the circuit board
Automatically Triggered at every 50 ms
Ascii output format
On Board Burst LED Indicator shows measurement in progress
3-pin header makes it easy to connect using a servo extension cable, no soldering required

Applications:

Robot Navigation
Obstacle Avoidance
Measuring Distance Devices
Engineering Measurement Tools

Pin Voltage	3.3 V
Sensor Detects	280-390 nm
Compact QFN package	4.0 mmx3.7 mmx0.7 3 mm

The ML8511 sensor breakout is an easy to use ultraviolet light sensor. The MP8511 UV Sensor outputs an analog signal in relation to the amount of UV light it detects. This can be handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions. This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. The ML8511 sensor is very easy to use. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm²). If your microcontroller can do an analog to voltage conversion, then you can detect the level of UV. Next, connect the following ML8511 breakout board to Arduino:These last two connections are a little different. Connect the EN pin on the breakout to 3.3V to enable the device. Also connect the 3.3V pin of the Arduino to Arduino analog pin 1. This example uses a neat trick. Analog to digital conversions rely completely on VCC. We assume this is 5.0V, but if the board is powered from USB this may be as high as 5.25V or as low as 4.75V. Because of this unknown window, it makes the ADC on the Arduino fairly inaccurate. To fix this, we use the very accurate onboard 3.3V reference (accurate within 1%). So by doing an analog to digital conversion on the 3.3V pin (by connecting it to A1) and then comparing this reading against the reading from the sensor, we can extrapolate a true-to-life reading, no matter what VIN is (as long as it’s above 3.4V).

Features:

Optical sensor to UV-A and UV-B
Realize equalization of an output voltage by trimming
The analog voltage output proportional to UV light intensity
Low current operation ( 300µA Typ. ) and low standby current ( 0.1µA Typ. )
The TSV-CSP version is under development for the further small size package( 2.1 × 1.8mm )
