Sensors are a device that detects or measures a physical property and records, indicates, or otherwise responds to it. It can detect and respond to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena.

Top 15 Latest Sensor Projects for Arduino Beginners:

Here we present you Top 15 Latest Sensor Projects for Arduino Beginners.

1. Color Sensor:

The Color Sensor is a complete color detector. It consists of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. It can detect and measure a nearly limitless range of visible colors to a certain degree. The color of an object we can see in fact is the chromatic light the object reflects in the white light (sunlight) after it absorbs the rest. The white color is a mixture of various visible colors, which means it includes each colored light like red (R), yellow (Y), green (G), blue (B), and purple (P). Based on the theory of three primary colors, any color is made by mixing the three primary colors (red, green, and blue) in a certain proportion.

2. Alcohol Level Meter using Arduino & MQ-135 Alcohol/Gas Sensor

5. Temperature Sensor:

In general, a temperature sensor is a device that is designed specifically to measure the hotness or coldness of an object.LM35 is a precision IC temperature sensor with its output proportional to the temperature (in °C). With LM35, the temperature can be measured more accurately than with a thermistor.

Here are 2 LM35 Temperature Sensor Project:
1. Digital Thermometer Using Arduino & LM35 Temperature Sensor

2. Temperature Based Fan Speed Control & Monitoring With Arduino

6. Sound Sensor:

This module allows you to detect when the sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op-amp. The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the setpoint, an LED on the module is illuminated and the output.

7. Flame/Fire Sensor:

A flame sensor module that consists of a flame sensor (IR receiver), resistor, capacitor, potentiometer, and comparator LM393 in an integrated circuit. It can detect infrared light with a wavelength ranging from 700nm to 1000nm. The far-infrared flame probe converts the light detected in the form of infrared light into current changes. Sensitivity is adjusted through the onboard variable resistor with a detection angle of 60 degrees.

8. Touch Sensor:

Touch sensor technology is slowly replacing mechanical objects like mouse and keyboard. A touch sensor detects a touch or near proximity without relying on physical contact. Touch sensors are making their way into many applications like mobile phones, remote controls, control panels, etc. Present-day touch sensors can replace mechanical buttons and switches.

9. PIR Sensor:

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually, this radiation isn’t visible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose.

10. Accelerometer Sensor:

An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity or speed divided by time. It measures Proper acceleration, being the acceleration of a body in its own instantaneous rest frame, is not the same as coordinate acceleration, being the acceleration in a fixed coordinate system.

11. Ultrasonic Sensor:

As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves.
The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception.

Here are 3 HC-SR04 Ultrasonic Sensor Project:
1. Distance Measurement Using Arduino & HC-SR04 Ultrasonic Sensor
2. Blind Walking Stick Using Arduino & Ultrasonic Sensor HC-SR04
3. Arduino RADAR Model using Ultrasonic Sensor for Detection & Ranging

12. Humidity Sensor:

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Here is a DHT11/DHT22 Humidity Sensor Project:

Live Weather Station using Arduino, RTC, Pressure & Temperature Sensor

13. IR Sensor:

An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the motion. These types of sensors measure only infrared radiation, rather than emitting it that is called a passive IR sensor.

Here is a IR Sensor Project:

14. LDR/Light Sensor:

Photoresistors, also known as light-dependent resistors (LDR), are light-sensitive devices most often used to indicate the presence or absence of light or to measure the light intensity. In the dark, their resistance is very high, sometimes up to 1MΩ, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity. LDRs have a sensitivity that varies with the wavelength of the light applied and are nonlinear devices. They are used in many applications but are sometimes made obsolete by other devices such as photodiodes and phototransistors.

Here are 2 LDR/Light Sensor Project:
1. Arduino Based Solar Tracker Using LDR & Servo Motor
2. Home Security Alarm Using LDR, PIR Sensor & Arduino for Night
3. Laser Light Security System using Arduino with Alarm

15. UV Ray Sensor:

The ML8511 is a UV sensor, which is suitable for acquiring UV intensity indoors or outdoors. The ML8511 is equipped with an internal amplifier, which converts photo-current to voltage depending on the UV intensity. This unique feature offers an easy interface to external circuits such as ADC. In the power-down mode, the typical standby current is 0.1uA, thus enabling a longer battery life.
