Atmega8 measures ambient temperature and relative humidity using HSM-20G sensor

Leave a Comment / AVR ATmega Projects, Temperature Measurement Projects /

In one of my previous posts, I discussed about Sensirion’s SHT11 and SHT75 sensors, which are capable of measuring both temperature and relative humidity. They are digital sensors and provide fully calibrated digital outputs for temperature and relative humidity. I also illustrated how to interface those sensors with a PIC microcontroller. Shawon Shahryiar from Dhaka, Bangladesh shared this project

Intelligent temperature monitoring and control system using AVR microcontroller

Leave a Comment / AVR ATmega Projects, Temperature Measurement Projects /

Controlling temperature has been a prime objective in various applications including refrigerators, air conditioners, air coolers, heaters, industrial temperature conditioning and so on. Temperature controllers vary in their complexities and algorithms. Some of these use simple control techniques like simple on-off control while others use complex Proportional Integral Derivative (PID) or fuzzy logic algorithms. In

The Arduino Weather Station / Thermostat using ATmega328 microcontroller

Leave a Comment / AVR ATmega Projects, Sensor - Transducer - Detector Projects, Temperature Measurement Projects /

I’ve always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I’ve been playing with the Arduino Microcontroller, and

Temperature Control For Kitchen Appliances

Leave a Comment / AVR ATmega Projects, Temperature Measurement Projects /

In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning
