Introduction to USB DrDAQ Sensors Thanks to the built-in sensors for light, sound and temperature you can start using your USB DrDAQ Data Logger straight out of the box. The USB DrDAQ also has an RGB LED that you can program to show any 1 of 16.7 million colours. When you want to do more with your DrDAQ you can thanks to the external sensor sockets. Simply buy an external sensor and your DrDAQ can measure humidity, oxygen levels, external temperatures and more.

Data Logging and Oscilloscope Soft ware for USB DrDAQ A PC-based data logger is only as good as its software — that’s why the USB DrDAQ comes with a complete software package that enables you to use your DrDAQ not only as a data logger but also as an oscilloscope and AWG too. Both PicoLog and PicoScope are fast and easy to use. PicoLog PicoLog data acquisition software is a powerful yet flexible program for collecting, analysing and displaying data.

External Sensors and Probes As well as the built-in sensors, USB DrDAQ has sockets for optional external sensors. When a sensor is plugged into 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. DD100 Temperature Sensor DD103 Oxygen Sensor A high-accuracy general purpose temperature sensor with a 2 metre lead.

External Sensors and Probes PP066 Reed Switch The reed switch sensor can be used to detect the presence of a magnetic field such as from a bar magnet or an electromagnet. Alternatively, a simple external switch can be wired to the internal screw terminals. It has a fast response time of 2 ms so can be used as an alternative to a light gate for timing applications. Other uses include monitoring the amount of time a door is left open or a machine running.

DrDAQ Science Experiments Our website has a number of scientific experiments utilising the DrDAQ unit. The example below uses the DrDAQ with the addition of a pH probe to measure the pH scale over the entire pH scale of a range of common drinks. Recently dentists have begun warning about the dangers of drinking acidic drinks. Teenagers, they suggest, who drink large amounts of fizzy ‘pop’ drinks suffer from tooth erosion whereby the enamel covering of the tooth is dissolved by the acid in the drink.
