|
|
|
|||
|
|
The pulse meter sensor allows you to count the number and frequency of pulses on any pin. It is intended to be a drop-in replacement
|
|||
|
|
for :doc:`integration sensor </components/sensor/pulse_counter>`, but offering better resolution.
|
|||
|
|
It measures the time between rising edges on a pin, for each pulse it outputs the frequency in pulses/min.
|
|||
|

# Example configuration entry
|
|||
|
|
sensor:
|
|||
|
|
- platform: pulse_meter
|
|||
|
|
pin: 12
|
|||
|
|
name: "Pulse Meter"
|
|||
|
|
|
|||
|
|
Configuration variables:
|
|||
|
|
------------------------
|
|||
|
|
|
|||
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin to count pulses on.
|
|||
|
|
- **name** (**Required**, string): The name of the sensor.
|
|||
|
|
|
|||
|
|
- **internal_filter** (*Optional*, :ref:`config-time`): If a pulse shorter than this
|
|||
|
|
time is detected, it’s discarded and no pulse is counted. Defaults to ``13us``. For S0 pulse meters that are used to meter power consumption 50-100 ms is a reasonable value.
|
|||
|
|
|
|||
|
|
- **timeout** (*Optional*, :ref:`config-time`): If we don't see a pulse for this length of time, we assume 0 pulses/sec. Defaults to ``5 min``.
|
|||
|
|
- **total** (*Optional*, :ref:`Sensor <config-sensor>`): An additional sensor that outputs the total number of pulses counted.
|
|||
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|||
|
|
|
|||
|
|
Converting units
|
|||
|
|
----------------
|
|||
|
|
|
|||
|
|
The sensor defaults to units of “pulses/min”. You can change this by using :ref:`sensor-filters`.
|
|||
|
|
For example, if you’re using the pulse meter with a photodiode to
|
|||
|
|
count the light pulses on a power meter that outputs 1000 pulses per kWh,
|
|||
|
|
you can use the following to output instantaneous usage in kW:
|
|||
|
|
|
|||
|
|
.. code-block:: yaml
|
|||
|
|
|
|||
|
|
# Example configuration entry
|
|||
|
|
sensor:
|
|||
|
|
- platform: pulse_meter
|
|||
|
|
pin: 12
|
|||
|
|
unit_of_measurement: 'kW'
|
|||
|
|
name: 'Electricity Usage'
|
|||
|
|
filters:
|
|||
|
|
- multiply: 0.06
|
|||
|
|
|
|||
|
|
Counting total pulses
|
|||
|
|
---------------------
|
|||
|
|
|
|||
|
|
When the total sensor is configured, pulse_meter also reports the total
|
|||
|
|
number of pulses measured. When used on a power meter, this can be used to
|
|||
|
|
measure the total consumed energy in kWh.
