user55387: Someone could help me?
I want to use dht11 with arduino and esp. Both will read data from dht11
the problem is that simultaneously cannot be done. So the solution will be to set one as a master and the other one as a slave. 
the control will be done like so...
another wire from arduino pin->set as output ->esp pin->set as input.
if wire == 1 then dht11 will be read by arduino 
if wire == 0 then esp will read dht.
with some delay ofcourse. but the problem is that i dk how to stop the communication between one board and the sensor when the other board will read it. so does it not exist any conflict

user55782: Also.. i would see a problem there. Lets say so..
Sensor data.
Gnd. 
Vcc
uC 2560
uC Esp 
If sensor data is linked to both uC
And  use a line dht_available btween 2560 and esp to handle the uC reading.. then..
If dht_available == HIGH then 2560 read after switch dht line to Low
If dht_available == LOW then esp read after reading dhtline》 HIGH
But the sensor wil continue to send data to both.. regqrding the dhtline is high or low.
I dk how to say to sensor.. if dhtline is LOW stop sending data to 2560 because is esp time to read.
