Thomas (LA3PNA) has designed and built a thermocouple meter, that is available on GitHub: I have designed a thermocouple meter for use for obtaining temperature readings from thermocouples. Its used together with the thermal chamber described elsewhere on this site. The design is done primarily as a programmable instrument, but it has a OLED display, […]

Building an ATmega 1284p based data logger
A detailed instructions of how to build an ATmega 1284p based data logger: In this tutorial, a logger is built using a 3.3v Moteino MEGA with a 1284p CPU @ 16Mhz, w 4K eeprom,16K SRAM for variables & 128K program space. Considerably more than the 328’s 1K eeprom, 2K ram & 32K progmem. Also has […]
Pro mini logger project for the classroom
Edward Mallon writes: Dr. Beddow’s instrumentation class has been building the 2016 version of the Cave Pearl datalogger for more than three years, and feedback from that experience motivated a redesign to accommodate a wider range of student projects while staying within the time constraints of a typical lab-time schedule. The rugged PVC housing from […]
Tutorial: Adding the SSD1306 OLED screen to an Arduino logger (without a library)
Edward Mallon writes: While I loved the Nokia 5110 LCD’s readability in full sun, the pressure sensitivity was a real problem for the underwater units. So I started noodling around with some cheap OLED screens from eBay. With the exception of the init & XY functions (which are more complicated on the 1306 controller) the […]
Video tutorials: Building the Arduino based data loggers
From the comments on our Arduino data logger post: A visiting researcher dropped by our humble basement workshop with questions about the physical skill level students would need if they added one of our DIY data loggers to their environmental curriculum. I figured the easiest way to cover that was to simply build one, while they […]
Adding the Nokia 5110 LCD to your Arduino data logger
From the comments on our ChipKIT based weather station using BME280 sensor module post, Edward Mallon writes: A lot of us have ended up at this sensor / screen combination. But I couldn’t afford the extravagance of six dedicated control lines on our little pro mini based loggers. However with some slight modification, you can drive […]
Arduino Tutorial: Adding sensors to your data logger
Edward Mallon writes: This post isn’t another How-To tutorial for a specific sensor because the Arduino community has already produced a considerable number of resources like that. You’d be hard pressed to find any sensor in the DIY market that doesn’t give you a dozen cookbook recipes to follow after a simple Google search. In […]
Arduino data logger update
An update on Edward Mallon’s Arduino data logger project we covered previously: If you need a logger with a cheap durable housing, it’s still hard to beat the Dupont-jumper build released in 2016. But sometimes I need more of a bare-bones unit for bookshelf test runs while I shake down a new sensor. I can […]
Open source data logger
An Arduino Nano-based open source data logger by Liudr. I have been designing data logger for a number of years. This is my answer to lots of data logging needs. An Arduino Nano-based open source data logger More details at Liudr’s blog.
Logging I2C Data with Bus Pirate and Python
Scott Harden writes, “I’m working on a project which requires I measure temperature via a computer, and I accomplished this with minimal complexity using a Bus Pirate and LM75A I2C temperature sensor.” More details at SWHarden.com. Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
DIY Arduino ProMini data logger
Ed Mallon blogged about his DIY ProMini data logger build: Typical pro-mini loggers built with this design sleep at 0.25mA, before extra sensors are added. At that current draw, the logger should deliver approximately six months of operation on three brand new AA batteries with a 15min duty cycle; depending on sensor load.
Simple Arduino SD-Card GPS/NMEA Datalogger
KF5OBS writes: This article is going to show how to build a minimalistic GPS datalogger. The GPS logger is based on the Arduino platform and stores raw NMEA sentences from pretty much any GPS module to a SD card. More details at KF5OBS blog.
Data logger deluxe version
An update on LuckyResistor’s data logger project we covered previously: Just to let you know the deluxe version of the data logger is almost done. The hardware is ready and tested – currently I finish the menu based software for the data logger. Menu based control with 5 capacitive inputs Record, view records, send records […]
Are my documents safe in the root cellar at ~80% humidity?
luckyresistor has been working on his Data Logger project: There is a large cellar where I could store unused items and documents, but the catch is the humidity there. It is a root cellar near a small brook and the humidity varies between 75% up to 90%. Archived material should never be exposed to humidity […]
LED logger v3
Bogdan of Electro Bob built a LED logger v3, that is available on github: In short: 16 LED channels are measured, one is kept for control of the sensor. For each LED the power supply and current are measured. The temperature of the aluminium plate is measured as well. In total there are 16 light channels, 15 […]
A Xively logger library for Spark Core
Davide Gironi writes: Xively (formerly Cosm and before that Pachube) is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that data. This library is a modular and configurable Xively data logger, built […]
Temperature data logger using PIC12F683 and DS1820
Rajendra over at Electronics Lab wrote an article on his temperature logger based on a Microchip’s 8-pin microcontroller, PIC12F683: A data logger is a device that records measurements over time. The measurements could be any physical variable like temperature, pressure, voltage, humidity, etc. This project describes how to build a mini logger that records surrounding temperature […]
Voltage recorder with playback
Dick Cappels wrote an article detailing his AVR data logger and voltage recorder: The recorder includes the functionality of a data logger but also plays back recorded voltages and can perform a curve trace function.A simple file system provides for up to 128 different sequential files totaling up to 130,000 samples. At 1 sample per […]
