For our ECE 4760 final project, we designed and built a running band that provides feedback to users with temperature and vibration. This provides an unique way to monitor running habits with temperature feedback. The running band attaches to a user’s upper arm and counts the number of steps the user takes. It then determines whether or not …

This project uses a Dallas DS1621 temperature sensor which indicates the temparature of the device. The temperature sensor has an thermal alarm output, which becomes high when the temperature of the device exceeds a user defined value. When the temperature drops below a user defined value, the alarm output becomes low. In this way any …
Generally, electronic devices produce more heat. So this heat should be reduced in order to protect the device. There are many ways to reduce this heat. One way is to switch on the fan spontaneously. This article describes a circuit that automatically, switches the fan when it detects the temperature inside the device greater than …

In this project we are going to design a circuit for measuring temperature. This circuit is developed using “LM35”, a linear voltage sensor. Temperature is usually measured in “Centigrade” or “Faraheite”. “LM35” sensor provides output based on scale of centigrade. LM35 is three pin transistor like device. It has VCC, GND and OUTPUT. This sensor …

For my final project I built a sous-vide immersion cooker: Sous-vide is a method for cooking food in a temperature-controlled water environment for longer than normal cooking times, at an accurately regulated temperature. Sous-vide cookers are often used in high-end restaurants. In the past few years, however, they have become more popular in household kitchens. …

Temperature monitoring have wide application in daily life. In modern day keeping an eye on temperature of places such as server rooms, hospital rooms, warehouses and green houses can help solve many problems. But with the use of normal temperature sensors, someone needs to go to the place in order to view the temperature. But …

A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. NTCtemp is a simple AVR library to read temperature from a thermistor connected to an atmega micro. The library implements three models convert adc value read from analog input to temperature: Steinhart-Hart Thermistor Equation Beta Model Equation Lookup …

This thermostat is built around an ATMega164 and a TC1047A temperature sensor. It controls your furnace and air conditioner. It is not programmable, although it has a clock and is capable if some additional code were written (any volunteers?). The unique feature is that instead of a bunch of buttons and switches, I used a single pushbutton rotary encoder, for a very simple user interface. …
I’ve had the HobbyKing Rattler for some time now and I’ve been making small modifications here and there which have accumulated over time and has gotten to the point where it would be nice to have everything on a custom PCB. Here’s how everything looks at the moment, pretty messy with kapton tape wrapped around …
AVR Microcontroller based Temperature Controller, it uses LM35 Temperature Sensor for measurement of temperature and 16×2 LCD is used to display temperature set point, Heater Status and current temperature, It controls temperature by turning on and off of the heater using relay. This project is very useful for controlling of temperature, It can be used …
