8 channel LCD Teperature meter using microcontroller

Description This is the fully featured, jammed packed temperature readout unit. I can measure temperature from up at 8 DS1820 digital temperature sensors all on the same 1-wire bus. That's right only 3 wires are needed to go to all the temperature sensors, GND, VCC and 1-wire data. All sensors will connect to the same cable! Anyone who has used the DS1820's will know that each DS1820 sensor will have a 48bi ...

Open Source AVR Temperature Controller using ATmega48 microcontroller

The open source project allows you to control DC appliances based on the temperature of two thermistor inputs. It uses AVR ATmega48 as main processor. The controller has both green and white LEDs to indicate status. The project output is connected to N-Channel MOSFET, AOD444, for switching with current up to 4A. For higher current you can use relay. To get you started, Jeffrey Nichols from ubertechnics has ...

Power usage monitor using Atmel AVR using Atmega168 microcontroller

This project uses Atmega168 microcontroller to compute the power usage at home and logs it to an SD card. It has a graphical LCD display too that shows the power usage as a strip chart. Besides, the voltage and current waveforms can also be displayed on the LCD. The current is measured using a pair of current transformers whereas the voltage is measured using a 2000:1 voltage divider network. An LMC6484AIN  ...

Multi-channel temperature logger using Atmega48 microcontroller

This project describes how to use all the 8 ADC channels of an Atmega48 microcontroller to read temperature sensors and the measured data to a PC for logging by using the built-in USART capabilities of the chip. For demonstration, the temperature sensor used is LM335 that gives an output voltage proportional to the Kelvin temperature. The microcontroller is operated with a 9.21 MHz clock that works well for ...

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

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 with us ...

Intelligent temperature monitoring and control system using AVR microcontroller

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 algori ...
