  • Capacitive Touch Sensor Module for Arduino

    Capacitive Touch Sensor Module for Arduino

    Capacitive touch sensor module for Arduino and other microcontroller projects

    One side has a 9mm x 9mm capacitive touch area, and a TTP223 touch sensor IC on the reverse.

    An LED indicates when the switch is touched, giving a digital. It can be set either a high or low output, and momentary or latching output by joining or not joining the A and B connections: 

    A open = High output when touched
    A Closed = Low output when touched
    B open = Momentary switch action
    B Closed = Latching switch action
     
    Voltage : 3 to 5VDC
    PCB Size 14x10mm

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
