Main components
1README
README.mdCapacitive Moisture Sensor
A sensor used to detect the present soil moisture through a change in capacitance. The PCB has designed in KiCad and uses an interdigital capacitor design. The output signal from this board is a PWM with frequency that changes relative to the capacitance (soil moisture).

Questions
How big is the Capacitive Sensor PCB?
It measures 24.1 × 60.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Capacitive Sensor use?
7 parts, built around the TLC555N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Capacitive Sensor KiCad files?
From the harrydobbs/Capacitive-Moisture-Sensor repository on GitHub, at the commit this page was made from: the board is kicad/Capacitive Sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Capacitive Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask harrydobbs before reusing the design.
