Soil moisture with long cable...
Posted: 11 Jun 2018, 21:13
Hi.
I have a problem with my soil moisture sensor (P47), I have connected it to ESP board with a 5 mt. cable.
If I use a ESP01 board it's ok and work fine but with ESP07, ESP12 or NODEMCU board id don't work at all.
I'm sure the cause is cable lenght, if I short it I have no problem.
I tried to use GPIO4 - GPO5 anf GPIO0-GPIO2 on ESP07 and NODEMCU device, but all is the same...ESP don't find I2C device.
GIT version is mega-20180606 for all devices, do someone have some advice to fix this?
Thank
