Arduino Temperature and Humidity meter [DIY]
posted April 18 2012 6:23.15 by Giorgos Lazaridis




Quite some time ago i use the SHT15 sensor to make a humidity and temperature sensor with PIC microcontroller. Here is the same sensor used for this applications, but implemented with arduino and OLED display. Actually he uses the SHT11, but it is more or less the same. Click here to go.

DIY Home AC power logger
posted December 13 2010 6:10.16 by Giorgos Lazaridis




Here is a DIY home power usage logger, based on the AVR ATmega168 microcontroller. The output is displayed on a graphical LCD display as a bar graph. The power is calculated with the P=V*I formula. To get the current (I), he used 3 flyback coils from old TVs he had (has 3-phase power). Each coils generates a voltage according to the current of the line that is attached to. A 0.2 ohms current sense resistor allows him to measure the current. To have more accurate readings, he amplifies this current in 3 stages (X1, X10, X100) and uses the best fit gain. Data are then stored in an SD card. Read more info in his page.
