Last week, I discussed the construction of a network-capable temperature and humidity sensor using SHT21 and ENC28J60 with an ATmega328P microcontroller. In this post, I will show the results obtained so far and the techniques used to chart the data.
I did a project on temperature/humidity logging a couple of years ago. In that project I logged the temperature and humidity readings in my basement lab over the course of a year. One issue with the approach I took back…
I had almost forgotten about the experiment I started late last year using the data logger I built to log the temperature and humidity values in my basement lab for an entire year. The logger worked well during the initial…
I built a rather generic I2C data logger a few weeks back. As I mentioned in my earlier posts, it can be used to log data from almost any I2C slave devices with relatively little code modification.
In my last blog post, I showed you the schematic of a I2C data logger I built. Here I will discuss some sample code used for this data logger and how to make it even more flexible.
There is a popular data logger shield out there designed for Arduino using a DS1307 real time clock chip. And that design makes data logging extremely easy if an Arduino board is used.
