SENSORS / TOUCH / STANDALONE MOMENTARY CAPACITIVE TOUCH SENSOR BREAKOUT
DESCRIPTION
This breakout board is the simplest way to create a project with a single "momentary" capacitive
touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the
pad to activate the sensor.
When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED
lights up and the output pin goes high. You can also solder a wire to the middle pad and create
your own capacitive pad if the built-in one isn't suited to your project.

DESCRIPTION
TECHNICAL DETAILS
If you want to save power, the LED can be disconnected from the output pin (cut the trace
between the jumper marked as such). We designed this breakout to have the more-responsive
"fast mode" which draws about 0.5mA. If you need ultra-low (~50uA) power usage, the mode
jumper can be cut on one side & soldered closed on the other to fix it into that mode. Check the
datasheet for specific power usage measurements.
Comes with a fully assembled board, and a small stick of 0.1" header so you can solder and
plug it into a breadboard. For additional contacts, we suggest using copper foil, then solder a
wire that connects from the foil pad to the breakout.
The datasheet has many details on sensitivity, power usage, etc.
