This project started as an experiment to see if a water level sensor (with fixed intervals) could be built, using the Arduino ADCTouch library and capacitive sensors. Capacitive sensors have the ...

Breakout boards for stand-alone capacitive touch sensors. These are the simplest ways to create projects with capacitive touch. No microcontroller is required here - just power with 1.8 to 5.5VDC.

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal ... Circuit simulation made easy. A free online environment ... This requires 16 pieces of ...

Fig. 2: Circuit diagram of the capacitive touch keyboard. The sensor setup includes a medium to high-value resistor, some jumper wires, a small piece of aluminum foil. You can use any resistor value ...

The ESP32 capacitive touch PCB sensor circuit was designed for a single-sided board. We have used Eagle to design my PCB, but you can use any Design software of your choice. The 2D image of our C ...

Alps Electric has added the “HSHCAL101B” PC board module to its HSHCAL series lineup of capacitive digital temperature and humidity sensors for major home appliances.

Circuit Diagram for the PCB Piano Using Arduino Nano. The eight 1Mega Ohm Resistors are connected to the Arduino Nano's digital pin number 2 in the following circuit diagram. The digital pins 3 to 10 ...

The letter board is a 22 by 14 grid (308 total) of touch electrodes connected to three MPR121 12-channel capacitive touch sensors connected to an ESP32 via I2C.
