  • Vibration switch module for Arduino KY-002

    Vibration switch module for Arduino KY-002

    Vibration switch module for Arduino and other microcontroler projects

     
    This module is a switch that will detect small knocks and vibrations, it is more sensitive than the knock sensor (KY-031) so can be used in projects that need very slight movement to be detected. This switch will "make" when the module is moved.
     
     
    Voltage : upto 5VDC
    Size 19x15mm

  • Carbon Monoxide gas sensor module for Arduino MQ-7

    Carbon Monoxide gas sensor module for Arduino MQ-7

    Carbon Monoxide sensor module for Arduino and other microcontroler projects

     
    A Carbon Monoxide sensor detects CO in normal air conditions.
    The resistance of the sensor changes with CO levels giving a varying voltage on the analogue pin. A comparator supplies a digital output when the CO level reaches a certain level, set with the built in potentiometer.
     
    Please note, this sensor needs to run for 24-48 hours before first time use
     
    Voltage : 5VDC
    Current : 100mA
    Sensitivity : 10 to 10000ppm
    Size 32x21mm

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
