ESP8266 and Fermion MEMS Microphone as water flow sensor
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
hello,
am using the MEMS microphone attached to a water pipe as a water flow sensor.
when the valve is closed I get 1.6V ….
However when the valve is on and hot water flows through the pipe I don't see a difference to the voltage.
My sketch as follows
- platform: adc
pin: A0
name: "Water flow Sensor"
id: "water_flow_sensor"
icon: mdi:water
update_interval: 0.5s
filters:
- multiply: 3.3
- sliding_window_moving_average:
window_size: 10
send_every: 1
- or:
- throttle: 180s
- delta: 0.02
any help would be much apreciated!!!
thank you in advance !!
