Temperature/Humidity Data Logger — Trial Run
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. So...

I built a digital thermometer a couple of weeks ago. This thermometer uses an LM19 sensor calibrated for measuring a wide temperature range (-55 – 130 Celsius, -67 – 266 Fahrenheit) for outdoor...
View ArticleReading SHT21 Using TI MSP430 LaunchPad
SHT21 is a neat little temperature and humidity sensor from Sensirion and I have used it in a couple of my Arduino projects before. Given that the Vcc is 3 V for these sensors, interfacing with a 5V...

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...
View ArticleTemperature and Humidity Logging Over Ethernet — II
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...

It seems that you can’t visit to a microcontroller website without seeing a digital thermometer/hygrometer build of some kind. After all, it is pretty easy to build and at the same time quite useful as...
