How to Make a Digital Thermometer 1 4 Steps Circuit Diagram LM35DZ is capable of reading the temperature in Centigrade scale. The output voltage of the sensor is directly proportional to the temperature in centigrade. LM35 can be used in the range of -55ยฐC to +150ยฐC with +/- 0.75ยฐC accuracy. So let's learn how to design a Digital Thermometer Using Arduino & LM35 Temperature Sensor. Circuit digram for Digital Thermometer using Arduino and LM35 Temperature Sensor , is shown in the above figure. Make the connections carefully as shown in the schematic. Here 16x2 LCD unit is directly connected to arduino in 4-bit mode. Data pins of LCD namely RS, EN, D4, D5, D6, D7 are connected to arduino digital pin number 7, 6, 5, 4, 3, 2. Circuit Design of Digital Thermometer. LM35 is the temperature sensor used in this project. The output of the sensor is directly proportional to the temperature but in analogue form. Hence, the output of LM35 i.e. pin 2 is connected to analog input A0 of Arduino.
The entire circuit works off a 9V battery. Assemble the circuit on a general-purpose PCB and enclose in a small plastic box. Calibrate the thermometer using presets VR1 and VR2. After calibration, keep the box in the vicinity of the object whose temperature is to be measured. Sent by Mihail Dorutz, CH. Thanks a lot! Digital Thermometer Circuit The wiring for this project is far simpler than you might imagine. Using the circuit diagram above, you can create your own DIY digital thermometer with little effort, but we've also broken the diagram down below to make it easier to follow.
