Hi every body,
I want to connect pic microcontroller to a digital humidity-tremprature sensor SHT11 through a 100 meter distance wire. the sensor communicates through 1 serial clock and 1 serial data in a manner like i2c but it is not. the serial data is bidirectional. both signals are TTL.
How can i do that without loosing the signal.
Can I use optocouplers or what??
What is the circuit??
How much this is guarenteed to work and not affected by noise of long distance wires??
Thanks
