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 values. It has following features:

– Uses just one 8?pin chip, so very compact size circuit.
– Temperature range: 0 to +125°C.
– Can store up to 254 measurements.
– Sampling interval options: 1 sec, 1 min, 10 min
– Reset feature to clear all previous measurements.
– Serial transfer of recorded measurements to a PC
– Three tactile switches for user inputs and a LED indicator.

This project combines a GPS receiver module, a Microchip PIC microcontroller and a Secure Digital memory card to make a GPS data logger. With a large capacity and reasonably long battery life it is a very useful device for logging GPS position.

crazyrobotsoftware.com writes : As an educational experiment, I decided to build a small temperature sensor, and data logger. Since I have little experience with direct Analog to Digital (A->D) converters, I decided to start out with a little more “meaty” hardware. I used a Basic Stamp II (BOE) BS2-IC microcontroller to capture temperature using a Sensirion Temperature and Humidity Sensor, and display using a 2×16 Serial Display. [via]

This is a Data logger to save values from a tipping-bucket rain gauge.It consist of on-board 4mBit (512kB) Dataflash is used to store the values. Readout to the Windows download software developed for this project takes place via serial port (RS232).
