DrDAQ represents a breakthrough in data logging. Simply plug DrDAQ into any Windows PC, run the supplied software and you are ready to collect and display data. DrDAQ draws its power from the parallel port, so no batteries or power supplies are required.

DrDAQ has built in sensors for light, sound (both sound level and sound waveforms) and temperature. It can also measure voltage and resistance. In addition it has a socket for standard pH electrodes and connectors for optional external sensors (temperature, humidity, pressure and more).

As well as the built in sensors, DrDAQ has sockets for optional external sensors. When a sensor is plugged in to the external sensor sockets, the software detects it and automatically scales readings. For example if a temperature sensor is plugged in readings are displayed in °C or if a humidity sensor is plugged in, readings are displayed in %RH.

External sensors are optional extras so can be purchased at any time. It is however cheaper to purchase sensors at the same time as a DrDAQ. See the DrDAQ value packs page for more information. Details of the external sensor sockets are provided with DrDAQ. This allows users (and third party manufacturers) to develop their own sensors.
