Interfacing DS18b20 Temperature Sensor with Arduino UNO Now that we have understood how the DS18b20 Temperature Sensor works we can connect all the required wires to Arduino UNO. The Connection ...

Block Diagram & Simulation The circuit reads the temperature from the LM35 sensor, displays the values in the serial monitor, and lights up the corresponding LED: Red LED: Temperature ≥ 30°C Yellow ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.
