Contactless Infrared Thermometer (Pyrometer) using MLX90614 and MSP430

The device is designed for contactless measuring and monitoring temperature of objects. It is built on Melexis MLX90614 sensor and can measure temperatures in the range from -70°C to +380°C with 0.5°C accuracy and 0.01°C resolution. The period of measurements can be set in the menu from 1 sec to 1 min in 10 sec increments. It is also possible to record the temp measurements and upload them to a computer via ...

Passive Infrared Detector Circuit

Summary The infrared (IR) is invisible radiant energy, electromagnetic radiation that we cannot see with our eyes, but we can sometimes feel on our skin as heat. The infrared light falls just outside the visible spectrum, beyond the edge of what we can see as red. Most of the thermal radiation emitted by objects near room temperature is infrared. The circuit uses a MCP6032 microchip operational amplifier. T ...

Distance Measurement using Infrared Sensor with ADC0804 & 8051 Microcontroller

Summary This project primarily consists of four units: Microchip Technology's SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16x2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being measured. The output voltage level of this ...

Infrared Theremin Using Atmega1284

Introduction A modern-day twist on the classic theremin musical instrument. This project uses two IR sensors and the ATMEGA1284P microcontroller to create an inexepensive, easy-to-use theremin. The theremin is a musical instrument which is controlled by the electromagnetic field your body body produces naturally. One hand is used to control the volume of the instrument, and the other hand controls the pitch ...

Everest Interscience Awarded U.S. Patent for Infrared Visible Targeting System

Tucson, AZ (Vocus) April 5, 2008 Infrared thermometers, such as those manufactured by Everest Interscience, have been used to measure surface temperatures of a variety of targets. A major problem with infrared thermometers of knowing where the temperature measurement is being taken, that frustrates end users and prevents more widespread acceptance of infrared thermometry, has been solved by Everest. This ma ...
