The Light and Temperature Data-logger Add-on Pack for Arduino.
- Adafruit data logger shield for Arduino (Assembled)
- 4 GB SD card
- Light sensor with matching 10K resistor
- Temperature sensor (-40 degC to 125 degC)
- 6 x AA battery holder with 2.1mm jack (unassembled)
You'll need 6 AA batteries, some wire and soldering tools to assemble the project.
For more information, including libraries, schematics and examples see the data logger shield webpage
Tested works with Arduino Uno, Leonardo, and Mega R3 or later.
The new and improved data logging shield
Our latest version of this popular shield has all the features of the popular original, but comes pre-assembled. You can be up and running with it in less than 15 minutes - saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program. This tutorial will also show you how to use two free software programs to plot your data. The included Real Time Clock timestamps all your data with the current time, so that you know precisely what happened when!
The data logger is a reliable, well-rounded and versatile design. It is easily expanded or modified and come well supported with online documentation and libraries.
- SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card
- Real time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup lasts for years
- Included libraries and example code for both SD and RTC mean you can get going quickly
- Prototyping area for soldering connectors, circuitry or sensors.
- Configurable indicator leds
- Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
SD/MicroSD Memory Card (4 GB SDHC)
Add mega-storage in a jiffy using this 4 GB micro-SD card. It comes with a SD adapter so you can use it with any of our shields or adapters! Preformatted to FAT so it works out of the box with our projects. Tested and works great with our Wave shield, Data logger shield and GPS shield, and micro-SD adapter as well as any other device in the Adafruit shop that uses (micro)-SD cards!
Please note! This is an SDHC card, and may not work with very old projects or products that only support SD cards. All of the Adafruit projects and products use SD/HC-compatible code. Make sure you can use this card before purchasing for non-Adafruit products. The brand itself may vary but we use only quality name-brand from reputable suppliers
Photo cell (CdS photoresistor)
CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ.
TMP36 - Analog Temperature sensor
Wide range, low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature. To use, connect pin 1 (left) to power (between 2.7 and 5.5V), pin 3 (right) to ground, and pin 2 to analog in on your microcontroller. The voltage out is 0V at -50°C and 1.75V at 125°C. You can easily calculate the temperature from the voltage in millivolts: Temp °C = 100*(reading in V) - 50
See the webpage for datasheets and more information. For a full tutorial with wiring diagrams, code examples and project ideas, please read the temp. sensor tutorial page!
6 x AA battery holder with 5.5mm/2.1mm plug
Make a portable power brick with plenty of juice! Use Alkaline AA's for a 9V 3000-4000mAh power supply, or rechargeable NiMH for 2000mAh 7.5V supply. Either one is good for running electronics that have a 5V voltage regulator (thus requiring a 7V+ supply). Will last about 10 times longer than a 9V
Batteries not included.
Perfect for portable Arduinos! Batteries not included. Some quick soldering is required to attach the jack to the holder.
