HC-SR04 Ultrasonic
|
It uses sonar to determine distance to an object like bats do. It offers
excellent non-contact range detection with high accuracy and stable readings in
an easy-to-use package. It comes complete with ultrasonic transmitter and
receiver modules.

IR Infrared Obstacle Avoidance Sensor
|
An IR sensor can measure the heat of an object as well as detects the motion. It
is used in robots to detect objects near the sensor. These sensors have a
digital output pin that outputs a signal when it detects an object. When the
module detects an obstacle, the green indicator light on the board lights up.
The module detects the distance 2 ~ 30cm, detection angle 35 °.

|
Soil Hygrometer Detection
|
It is a water sensor that can be used to detect soil moisture. It outputs a high
signal when the moisture is above a certain threshold. You can also read an
analog signal whose value is proportional to the moisture level. Use this sensor
to create an automatic self-watering plant.
|
|
|
4.
|
Microphone Sensor
|
It is used to detects sound signals and converts them into an electrical signal.
It has 2 outputs: Analog output or Digital output. Digital output It sends a
high signal when the sound the sound intensity reaches a certain threshold. The
threshold-sensitivity can be adjusted via potentiometer on the sensor.
|
|
|
5.
|
Digital Barometric Pressure Sensor
|
It is used to measure the absolute pressure of the environment/ air around them.
By converting the pressure measures into altitude, you have a reliable sensor
for determining the height of your robot or projectile, for example. This sensor
also measures temperature and humidity.
|
|
|
6.
|
Photoresistor Sensor
|
It is used for light detection or detect the intensity of light with an Arduino.
It has a potentiometer knob that can be adjusted to change the sensitivity
of LDR towards light.
|
|
|
7.
|
Digital Thermal Sensor
|
It is used to detect the ambient temperature. Through the adjustment of the
potentiometer, you can change the temperature detection threshold.
|
|
|
8.
|
Rotary Encoder Sensor
|
It is a type of position sensor which is used for determining the angular
position of a rotating shaft. It generates an electrical signal either analog or
digital according to the rotation movement.
|
|
|
9.
|
MQ-2 Gas Sensor
|
It is used in gas leakage detecting equipments in family and industry. The
resistance of the sensitive component changes as the concentration of the target
gas changes. The MQ-2 gas sensor is sensitive to LPG, i-butane, propane,
methane, alcohol, Hydrogen and smoke.
|
|
|
10.
|
SW-420 Motion Sensor
|
It is used to detect various vibrations that beyond the threshold.
|
|
|
11.
|
Humidity and Rain Detection Sensor
|
It is used for rain detection. It can be used as a switch when raindrop falls
through the raining board and also for measuring rainfall intensity.
|
|
|
12.
|
Passive Buzzer
|
It is a sound making module. You set high or low to drive this module. By
changing the frequency you’ll hear a different sound.
|
|
|
13.
|
Speed Sensor (Tachometer)
|
It allows you to test the speed of the motor. It is used for motor speed
detection, pulse count, position limit, and so on.
|
|
|
14.
|
IR Infrared Flame Detection Sensor
|
It is used to detect a flame or a light source of a wavelength in the range of
760nm to 1100 nm. Detection point of about 60 degrees, particularly sensitive to
the flame spectrum.
|
|
|
15.
|
5V 2-Channel Relay Module
|
It is used for the purpose of protection of the equipment connected with it.
These are used to control the high voltage circuit with low voltage signal in
applications audio amplifiers and some types of modems.
|
|
|
16.
|
Breadboard Power Supply Module 3.3V 5V
|
It is used to power up your breadboard circuits from an external power supply.
It supplies both 3.3V and 5V.
|
|
|
17.
|
HC-SR501 Pyroelectric Infrared Sensor
|
It is used to detect movement from humans or pets and is integrated with your
microcontroller.
|
|
|
18.
|
Accelerometer Module
|
It is used to measure the acceleration. It’s commonly used in portable devices
and video game controllers to detect movement and actions from the player.
|
|
|
19.
|
DHT11 Temperature and Humidity Sensor
|
It is used to measure temperature and humidity in your room or outside. It is
integrated with a high-performance 8-bit microcontroller.
|
|
|
20 or 21.
|
RF 433MHz Transmitter/Receiver
|
If you need data sent from one microcontroller to another. It is used to
transmit and receive the data because it has high volume of applications than
IR. RF signals travel in the transmitter and receiver even when there is an
obstruction. It operates at a specific frequency of433MHz.
|
