Laser transmitter module for Arduino and other microcontroler projects
This module has a 650nm Red laser diode head with resistor. It will produce a focused red dot. Please use with caution and never look directly into the laser or point it into anyone elses eyes.
RGB full colour SMD LED module for Arduino and other microcontroler projects
This module has a 5050 surface mount RGB LED that can be used to create virtually any colour by varying the intensity of the 3 colours by using the PWM output. Resistors will be needed to connect to an Arduino.
Photo interupter module for Arduino and other microcontroler projects
This module has an optical slot device and 2 resistors fitted. The sensor will detect if an object is blocking the light between the emitter and dector in the photo interupter and can triger a digital input in your microcontroler.
Bi-colour Red/Green 5mm LED module for Arduino and other microcontroler projects
This module is a 2 coloured 5mm LED with a common cathode that will iluminate either Red, Green or Orange (Red and Green together). You will need to use a resistor when connecting to an Arduino.
Temperature and humidity module for Arduino and other microcontroler projects
This module has a DHT11digital temperature and humidity sensor and a resistor. The DHT11 uses a thermister for the temperature sensing and a capacitive humidity sensor along with an internal IC to give a digital output with both temperature and humidity.
RGB full colour 5MM LED module for Arduino and other microcontroler projects
This module has a 5MM RGB LED that can be used to create virtually any colour by varying the intensity of the 3 colours by using the PWM output to each pin. Resistors will be needed to connect to an Arduino.
Mercury tilt switch module for Arduino and other microcontroler projects
This module has a small glass bead with a ball of mercury in it that will either make or break a contact if it is tilted. It also has a surface mount LED that can be connected to iluminate when the switch is activated.
5V relay module for Arduino and other microcontroler projects
This module has a 5V changover relay, protection diode, resistor and LED. This relay will allow the low current outputs from your microprocessor to switch much higher currents and voltage so you can control larger things from a digital output pin.
Tilt switch module for Arduino and other microcontroler projects
This module has a tilt switch that is normaly open and will close when the module tilts, it has a resistor connected in series with the switch so it can be used directly with a digital input on an Arduino when powered by 5VDC.
Dual axis joystick module for Arduino and other microcontroler projects
This module uses 2 10k potentiometers, one for the X axis and one for the Y axis, it also has a switch that is activated when the joystick is pressed down.
Hall effect magnetic standard linear module for Arduino and other microcontroler projects
This module uses a hall effect sensor to detect magnetic fields.It also has a comparator to give a digital output as well as an analogue output and a potentiometer to adjust the level for the digital output.
Flame sensor module for Arduino and other microcontroler projects
This module uses a photo diode that is sensitive to IR between 760-1100nM so it can detect the light of a flame.It also has a comparator to give a digital output as well as an analogue output and a potentiometer to adjust the level for the digital output.
Digital temperature sensor module for Arduino and other microcontroler projects
This module uses an NTC thermister to sense the temperature.It also has a comparator to give a digital output as well as an analogue output and a potentiometer to adjust the level for the digital output.
Bi-colour Red/Green 3mm LED module for Arduino and other microcontroler projects
This module is a 2 coloured 3mm LED with a common cathode that will iluminate either Red, Green or Orange (Red and Green together). You will need to use a resistor when connecting to an Arduino.
Percussion knock sensor module for Arduino and other microcontroler projects
This module is a switch that will detect being hit, it is not as sensitive as the vibration switch (KY-002) so can be used in projects that may be moving and an impact needs to be detected. This sensor acts like a switch that will "make" when the sensor is knocked.
Object detection/avoidance module for Arduino and other microcontroler projects
This module uses an IR diode and IR receiver that will detect if there is an object in front of the module. It also has 2 potentiometers to adjust the sensitivity of the module.
Line tracking sensor module for Arduino and other microcontroler projects
This module uses an IR transmitter and receiver that will detect how reflective the surface is in front of the module. It has a potentiometer to adjust the sensitivity of the module so it can detect if the surface is black or white.
Metal touch sensor module for Arduino and other microcontroler projects
This module uses a darlington NPN transistor and a comparator to detect when the base of the transistor (or what you connect it to) gets touched.It will give a digital output as well as an analogue output and it has potentiometer to adjust the sensitivity for the digital output.
High sensitivity sound sensor module for Arduino and other microcontroler projects
This module uses a high sensitivity microphone to detect sound levels. It also has a comparator to give a digital output as well as an analogue output and potentiometer to adjust the level for the digital output.
Microphone sound sensor module for Arduino and other microcontroler projects
This module uses a minature microphone to detect sound levels. It also has a comparator to give a digital output as well as an analogue output and potentiometer to adjust the level for the digital output.
Finger heartbeat measuring sensor module for Arduino and other microcontroler projects
This module uses abright IR LED and a phototransistor. When a finger is placed between the LED and transistor you will get an analogue output of light intensity that passes through the finger, this will vary every time the heart beats and give a heartrate.
