An optical dust meter that uses the GP2Y1010AU0F sensor library made with AVR Atmega

Sensor - Transducer - Detector Projects / Ibrar Ayyub

This project is a dust detector that use the GP2Y1010AU0F sensor. Attached you can also find the GP2Y1010AU0F sensor library for AVR Atmega.GP2Y1010AU0F is a dust sensor by optical sensing system. An infrared emitting diode (IRED) and an phototransistor are diagonally arranged into this device. It detects the reflected light of dust in air. Especially, […]

Atmega Alarmclock & Thermohumidity meter

First, rise and shine, let me introduce you to my project. I’ve crafted an Alarm clock with extended functionality, including a thermometer and a humidity meter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register

Galvanic skin response meter using Atmel mega32

Metering - Instrument Projects / Ibrar Ayyub

Introduction Our project measures the user’s skin conductance for monitoring his or her mental state. Summary Medical experiments have shown that the magnitude of the electrical conductance in a person’s skin is directly correlated to their emotional state. The short term changes in electrical conductances also correlate with a person’s mental response. We implemented an

ATtiny2313 Frequency Meter: Counting Architecture and Timing Limits

Electronics News Updates / Ibrar Ayyub

An ATtiny2313-based frequency meter counts T0 edges over a one-second gate and rebuilds a wide total from 8-bit overflows. This review examines the datasheet’s external-clock sampling limits and the accuracy questions the original project leaves open.

8 channel LCD Teperature meter using microcontroller

AVR ATmega Projects, LED Projects, Temperature Measurement Projects / Ibrar Ayyub

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
