I have tested it over 100 mtr wire iit works but I dont Know is it stable or not
and i also wanna to know that i am going to use 3.3 v board mounted Sensor for Humidity and temp can it be used for long distence
it also have an output of pulse
Thanks in advance

You couldn't use a i2c/UART transmission?

I2c is short range.
