Arduino Rs485 Module Schematic. This module see it here can be used to send arduino serial data over long distances up to 1 km using rs485 signals. The arduino uno will be the master receiver it will receive the temperature measurement and will display on the lcd display 20 x 4 i2c.
Rs 485 module as receiver. Enables sending and receiving data using the rs485 standard with rs485 shields like the mkr 485 shield. The arduino uno will be the master receiver it will receive the temperature measurement and will display on the lcd display 20 x 4 i2c.

This library supports the maxim integrated max3157 and equivalent chipsets. The arduino nano will be the slave transmitter it will read the ds18b20 sensor and send the measured value through the rs485 module. Now i m evaluating to use a ttl to rs485 module without de and re i think they have automatic direction control. Rs485 serial communication between arduino mega and arduino nano with visuino.
