Arduino temperature and light data-logging and chart plotting webmonitor. Arduino Temperature Logger. Just like every other good engineer in life, I thrive on data.
It doesn't even need to be solving a problem. Simply having the ability to say, "I know this," is awesome. Having some free time last month, I started playing with my Arduino again, and finally got around to ordering all the parts I needed for a project I've been thinking about for a long time. This is my Arduino-based temperature logger. On the breadboard, from left to right, is a serial real time clock, a 1Mb EEPROM, and lastly the serial temperature sensor.
Since pretty much everything uses I2C, I'll leave wiring it all up as an exercise for the student (Hint: connect everything to analog 4 & 5). Source code. Note that some of the features of the dumper (setting the clock, reading the clock), don't work. I measured the current draw as 42.5mA, so ignoring the loss in the power supply, that's only half a watt.
How It Works On power-up, the Arduino checks the CH (Clock Halt) flag on the DS1307 clock chip. Possible Extensions. Lukemiller.org» Blog Archive » A thermocouple datalogger based on the Arduino platform. Updated with new Arduino code July 8 2012.
It never hurts to collect more data, and I often find myself wanting to record temperatures from a few extra animals. Most (all?) Commercial thermocouple dataloggers that will record temperatures from multiple thermocouples cost several hundred or thousands of dollars. I set out to put together a relatively cheap 8-channel thermocouple datalogger based on the open-source Arduino development platform. My 8-channel thermocouple datalogger. By way of introduction, the Arduino development platform consists of a cheap and fairly easy-to-understand microcontroller board and associated software to easily program the microcontroller.
My datalogger setup consists of the Arduino board: Arduino Duemilanove. Quick & simple Arduino temperature logger. The other night I threw together a simple temperature data logger with my arduino.
I was programming to make the differential controller for the attic fan heat dodad and figured it would be good to log some temperatures while I'm at it. As the title says, its very simple to make. All you need is:ArduinoLM35DZ-ND some wire The total cost for parts would be less than $40 and you could make a 6 channel logger out of it with a few more sensors and some additional code.
The code is also very simple: Code: /* quick temp data logger */ // Variable declaration int temperature = 0; // variable to keep the actual value // Analog pin declaration int TsensorPin = 1; // temperature sensor pin void setup() { Serial.begin(9600); pinMode(TsensorPin, INPUT); } void loop() { temperature = analogRead(TsensorPin) * .512; Serial.print(temperature); Serial.println(","); delay(300000); } Here is what I ended up with.
Now, there is a slight problem. Hot water system datalogger. Data logging shield for Arduino [v1.0] ID: 243 - $19.50 : Adafruit Industries. Data-Logger Shield for Arduino.
