The TSL235 is a light-to-frequency converter. This library reads TSL235 output frequency and convert it to irradiance, and then to illuminance. Irradiance is the power of electromagnetic radiation per unit area (radiative flux) incident on a surface. It's expressed in watt per square metre, the symbol is Ee. In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a ...

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, it is effective to detect very fine particle like the c ...

Summary One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creating a thermometer started from a device called thermoscope, a thermometer without a scale. Several inventors developed it until Sir Thomas Allbutt invented the first practical 6-inch medical thermometer able to sense a bo ...

A non invasive current sensor is connected to the spark core (with a few components), and clamped around a cable in the Mains distribution unit. No wiring is required, however Do not try this at home, as the Mains Distribution Unit should not be tampered with unless one is Licensed to do so.   The back end is Web Application hosted on a LAMP (Linux Apache MySql PHP) setup. Initially it was hosted on a ...

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. 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 display similar like that. When I first see them I knew that I will made from it alarm clock. I'm programmer and ...

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 EDA meter designed to measure skin c ...
