  • 4 way 5V relay module for Arduino

    4 way 5V relay module for Arduino

    5V relay module for Arduino and other microcontroller projects

     
    This module has 4 x 5V changover relays with the option of using them through optocouplers. There is an LED for each relay to indicate when it has been activated.
    The relay allows the low current microprocessor outputs to switch higher currents and voltages. With the optocouplers it fully isolates the live side of the relays from your microprocessor, this will require a seperate 5V supply to power the relays.
     
    Trigger voltage : 5VDC
    Supply Voltage : 5VDC (only needed if using optoisolators)
    AC Switch ratings : 250V 10A
    DC Switch ratings : 30V 10A
    Size 73x52mm


    Item Number: RM4
    £5.50 (inc VAT £6.60)

  • Percussion knock sensor module for Arduino KY-031

    Percussion knock sensor module for Arduino KY-031

    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.
     
     
    Voltage :upto 5VDC
    Size 19x15mm


    Item Number: KY031

  • Rotary encoder module for Arduino KY-040

    Rotary encoder module for Arduino KY-040

    Rotary encoder module for Arduino and other microcontroler projects

    This module uses a 30 position rotary encoder with push switch.
    The rotary encoder works by having 2 switches (A&B) for each position that are slightly offset, indicating the direction of rotation by detecting if "A" switches before or after "B".
     
    Voltage : 5VDC
    Size 19x15mm
