New Sensor Module: Frequency Counter #378

Closed mschlenstedt closed 3 months ago

mschlenstedt commented 4 months ago

Hi,

based on the new sensor module "yfs201" I created a more flexible module, which will work with all hardware which creates a frequency (pulses) at the GPIOs. Examples are Flow Rate Sensors or Anemometers. The GPIOs of the Raspberry can detect 5 KHz (not confirmed, I found this on some older webpages).

Example config::

sensor_inputs:
- digits: 4
  module: meinflowmeter
  name: meinsensor
  retain: true
  pin: 17
  interval: 10
sensor_modules:
- module: frequencycounter
  name: meinflowmeter

The output of the module is the Frequency at the used GPIO in Hertz (Hz).
