[Magnus] pairs the off-the-shelf capacitive sensor with an ESP32 charged with reading it and reporting back to Home Assistant. It’s also outfitted with a heater to keep it at a constant ...

[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question speaks I2C and senses up to twelve simultaneous capacitive sense electrodes; break-out boards are ...

Models with the dynamic capacitive measuring principle detect a hand or finger for actuation; the output signal is actuated for 300 ms. This principle allows the sensor to ignore build-up on the ...

The sensing field must change from the electromagnetic domain to the electrostatic domain; the inductive proximity sensor must become capacitive. Capacitive proximity sensors detect a wide variety ...

The project's called Botanicus Interacticus, and centers around a custom-built capacitive sensor module, which pipes a very low current through an otherwise ordinary plant, then senses when and ...
