Infrared thermometer

Posted by kk99 Nov 15, 2017
I would like to show you a infrared thermometer with MLX90614 sensor, seven segment display HP QDSP-6040 and ATtiny2313 MCU. Sensor allow to measure temperature in following ranges: 1) -40 - 125 °C - in case of measurement of sensor temperature, 2) -70 - 380 °C - in case of measurement of object temperature. In project is implemented only measurement of object in Celsius degrees.   ATtiny2313 MCU communicates with sensor by SMBus. Measured value of temperature is shown on disp ...
Hi, I would like to show simple Christmas decoration. Cotton LED star was made from 5 orange LEDs, few pieces of hotmelt and cotton thread. Each LED diode is controlled by Digispark module with ATTINY85 module. Program was written in C language. Schematic: Photos: Video:   Source code in attachment. ...

Simple thermometer

I would like to show you a simple thermometer with single seven segment LED display HP 5082-7356, DS18B20 sensor and Digispark module. DS18B20 sensor is able to measure temperatures in range form -55 to 125 °C. Digispark module communicates with DS18B20 sensor by 1-Wire interface and reads temperature every 10 seconds. Value of temperature (stored as integer) is displayed on HP display. Schematic: Video:   Source code: sevensegtherm ...
