The aim of project is to build temperature and humidity controller for Mushroom Environment based on Arduino. The project comes with 3 sensors: Thermistors for temperature sensor, HS1100 for humidity sensor and MG811 for C02 sensor.

5 Channel USB Analog Sensor with AVR ATmega48

July 19, 2012 By: admin Category: AVR, Data Acquisition, Interfacing, USB No Comments →

This project demonstrates how to build a simple module to read analog sensor and send the data to PC using USB connection. The project uses ATmega48 as main processor and USB FTDI serial-to-usb cable. Simply put header pins on your device which you can plug into providing the microcontroller-computer link. No need for soldering surface-mount […]

AVR Thermocouple Temperature Meter

July 13, 2012 By: admin Category: AVR, Data Acquisition, Measurement, Microcontroller, Project, Sensor No Comments →

The benefit using thermocouple sensor for measure temperature is it has wide range measurement (-200 °C to +1350 °C / -328 °F to +2462 °F range for Type K), inexpensive, interchangeable, and is supplied with standard connectors. To get temperature value from output of a thermocouple, you need high precision amplifier and proper compensation circuit […]

Arduino Simple Remote Monitoring

June 19, 2012 By: admin Category: Arduino, Data Acquisition, Monitoring, Remote No Comments →

This simple remote monitoring project uses Eye-Fi wireless SD card and Data Logging Shield for Arduino. The Eye-Fi is tiny wireless memory card. It can be used to stores photos like regular SD card and transfer images to your computer, smartphone or to various photo-sharing sites using built-in Wi-Fi transceiver. No more extra USB transfer […]
