Its just a digital output off or on from that sensor, connect it to an aux pin and set it as a button input.

You dont need it to do anything just warn i assume?

I actually own a load of those sensors already

mmmm okeey i gonaa try . but i need listen incoming data for firstly liquid sensor and other things . can we chat from this if you want Login • Instagram

if you want to add a lot of different sensors then yuris unsupported sensor project is probably the way to go.

why are you trying to wire it into the telemetry port?

I already explained to you, you need to wire it to one of the aux pins using a servo connector

join the blue and black wire together and connect it to ground
the brown wire goes to 5v in the middle
and the yellow wire goes to the signal pin.

plug it into aux 1

set BTN_ENABLE = 1
set BTN_PIN1 = 50
set SERVO9_FUNCTION = -1

that should be it. you can use the BTN_FUNCTION paramter to set it to do something

and you can use the button test lua to see warnings on mission planner

github.com

ArduPilot/ardupilot/blob/master/libraries/AP_Scripting/examples/button_test.lua

-- This script is an example button functionality

local button_number = 1 -- the button numbber we want to read, as deffined in AP_Button

local button_active_state = true -- the 'pressed' state of the button

local last_button_state

function update() -- this is the loop which periodically runs

  local button_new_state = button:get_button_state(button_number) == button_active_state

  -- the button has changes since the last loop
  if button_new_state ~= last_button_state then
    last_button_state = button_new_state
    if button_new_state then
      gcs:send_text(0, "LUA: Button pressed")
    else
      gcs:send_text(0, "LUA: Button released")
    end

can i do that parametr on mission planner

geofrancis · June 29, 2022, 10:47am

yes you will need to refresh the parameters after setting BTN_ENABLE = 1 before you can set BTN_PIN1 = 50.

ddar · June 29, 2022, 11:03am

oohh ok thanks soo much

ddar · June 30, 2022, 1:23pm

i seted all parameters then what should i do .

ddar · June 30, 2022, 1:25pm

and how can i get the from sensor incoming data

geofrancis · June 30, 2022, 1:26pm

When you trigger the sensor you should see the button trigger showing on mission planner messages. You can use the lua script i put in the last post to give custom warnings.

The sensor just gives an off or on value when water is detected.

right now sensor not working

geofrancis · June 30, 2022, 1:28pm

Does the red light change when you put the sensor against your hand?

Have you got a 5v source connected to the servo 5v rail?

ddar · June 30, 2022, 1:32pm

yess i did like this but sensor not working

geofrancis · June 30, 2022, 1:32pm

You need to connect a 5v regulator, the servo rail is not powered from USB.
