A Little More Serious Frequency Meter using ATtiny2313 microcontroller

Leave a Comment / Using Atmega /

This is design for a frequency meter based on AVR microcontrollers. Maximum input frequency is specified to be 30 MHz in the multi-chip configuration, and in single-chip configuration, there are both 5 MHz and 10 Mhz versions operating with 10 and 20 MHz crystals, respectively. All versions have 9 1/2 digit resolution. I have  used

RS-232 Freq. Meter/Pulse Generator Based on Atmel ATtiny2313 using microcontroller

Leave a Comment / Using Atmega /

Simplicity in circuitry was the design direction. Zero mass (firmware only with no physical components) would the ultimate achievement. This instrument doesn’t have any front panel controls because the user interacts via an RS-232 terminal program at 9600 baud. I needed a frequency meter for my experiments in Nondu, Thailand, where I really don’t have

Electricity is the most required and important element of human life. We cannot imagine our day to day life without electricity. Electricity is generated using conventional (coal, diesel) and non conventional (water, wind, sunlight) energy sources. The recent and latest trend is to generate electricity from solar energy. The solar panel (made up of solar-photovoltaic

Irradiance Illuminance Meter using TLR235R sensor

Irradiance/Illuminance Meter using TLR235R sensor with AVR Atmega

Leave a Comment / Using Atmega /

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
