DrDAQ

DrDAQ is a low-cost data logger that simply plugs into the parallel port of any Windows PC.

DrDAQ has built in sensors for light and temperature, and a microphone to record sound. It can also measure voltage and resistance. In addition it has a socket for standard pH electrodes and connectors that allow the use of optional external sensors for measuring temperature, humidity, pressure and more.

Supplied complete with software and cables, the DrDAQ is ideal for classroom science experiments.
