Arduino Thermometer With LM35

Hello, everyone !!! Today I'm going to show you how to make a thermometer with Arduino and LM35 termperature sensor, builded on a breadboard and conected together with jumpers (bunch of cables :D). Step 1: Gathering The Parts This is the list the parts needed to make the thermometer. If you dont have a 10k pot you can use 50k like me ! 1x Arduino UNO board 1x Breadboard 1x 16x2 LCD display 1x LM35 sensor 1x ...

A DIY indoor thermometer plus hygrometer using PIC16F688

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) a ...

Digital & Binary clock with thermometer & hygrometer

Here we have a clock. It’s not “another clock”. It has digital and binary output. It also has a thermometer and a hygrometer. It’s not “another thermo-hygrometer”. It display’s absolutely humidity (gr/m3) also. Schematic   MCU I build it around Microchip PIC16F917, with internal Oscillator at 4MHz. I also build a serial port programmer, so I can programming it on-line, using the DL4YHF WinPic. Clock I ...

Contactless Infrared Thermometer (Pyrometer)

The heart of the device is TI's MSP430RF5728 microcontroller (μC) with FRAM type of memory instead of conventional Flash. This simplifies and speeds up writing to memory and from the user's viewpoint there is no difference between RAM and FRAM access. No preliminary block erase is needed by writing a single byte into FRAM. However, presently FRAM is slower than Flash. In FR57xx devices the maximum FRAM acce ...

4 DIGITS THERMOMETER USING DS18B20 DIGITAL SENSOR

Updated on 17/01/2016 (a and b segments were swapped on drawing) Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are calculated separately. The 7 segment LED is common cathode, 4 separate digits can be used with ...

Seven Segment Display Thermometer with PIC Microcontroller

The seven segment display is one of the most popular numeric displays used in many microcontroller applications because it’s cheap, robust and reliable. The seven segments actually consists of 8 LED (Light Emitting Diode) and it’s come with various sizes suitable for various numeric display application such as digital clock, counter, thermometer, humidity, etc. On this project we are going to show you how t ...

Bluz Grill Thermometer

With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermometers, but they require carrying around a separate readout. We wanted a way to read the termperature from our smartphone, so we took the just the thermometer and hooked it to bluz! Getting the thermometer to work was a bit ...

USB Indoor/Outdoor Thermometer using PIC18F2550 microcontroller

USB Indoor/Outdoor Thermometer (or, 'My first USB device') This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available in through hole versions. I use surface mount parts because its faster to make ...

Thermometer with PIC Microcontroller

In the last tutorial we learn about the multiplexing technique used with seven segment displays. We learnt how it saves i/o line by using persistence of vision. Only one digit is lit at a time, but to a human eye it is too fast to catch, so we see all four digit lit the same time. In this tutorial we will make a practical use of multiplexed seven segment displays. We will use them to show current room tempe ...
