ESPhome - connect pressure transducer?

[Vendril]

Hi,

Can you please show me where to connect wires for water pressure sensor?

1. Pressure Sensor - https://www.aliexpress.com/item/10050055...1802qhU8yT
   
2. Gravity: Analog Water Pressure Sensor (5V) - https://wiki.dfrobot.com/Gravity__Water_...7#target_5
   

RED = 
BLK = can i use any GND?
GREEN = A1?


How to use in ESPhome? I am very confused.

Code:

# Example configuration
# DC 0-5v - ANALOG_A1
  - platform: gpio
    name: "ANALOG_A1"
    id: ANALOG_A1
    pin:
    number: GPIO36

KC868-A8S v1.2


Thanks

yes, i think it's ok. if the sensor output dc 0-5v signal, you can connect with A8S board's A1,A2, because A3,A4 use by 4-20mA analog sensor.

Thanks, do you have example ESPHOME configuration file for using A1?

Will this work?

this need to test. you can connect with dc 3.3v to analog input port for a test. when value correct, then connect with your presure sensor.
