As well as the built-in sensors, the DrDAQ Data Logger 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 Centigrade (°C) or Fahrenheit (F), or if a humidity sensor is plugged in, readings are displayed in percentage Relative Humidity (%RH).
The really impressive thing about the USB DrDAQ is that it lets you use your own sensors, but if you don’t want to design and make your own sensors we have a range of sensors that you can buy to extend the capabilities of your DrDAQ.

PP163 : DrDAQ Humidity Sensor
|
|
This sensor is designed for the cost-effective measurement of relative humidity. When plugged into one of the external sensor sockets on DrDAQ (using the supplied 3 m cable) readings can be displayed in %RH. The sensor has a response time of 60 seconds and can operate over a 0 to 60 °C temperature range.

PP214 : DrDAQ Oxygen Sensor
|
|
Oxygen in air is measured using a galvanic cell sensor that connects to the external sensor sockets using the supplied three metre lead. Simply plug in the sensor and you are ready to measure.
Unlike previously available oxygen sensors, the DD103 Oxygen sensor can measure the full 0 to 100% range. This makes it ideal for many chemistry, biology and physics experiments.

|
DD011 : DrDAQ pH sensor
|
|
pH is measured using a standard electrode with a BNC connector. Pico supplies a robust epoxy bodied pH electrode ideal for educational use. It covers the full 0 to 14pH range. The electrode comes complete with a small bottle of storage solution to help prevent it drying out.
|
pH Sensor Specifications |
| Operating temperature |
0 to 60°C |
| Resolution |
0.02pH |
| Size |
12 x 120 mm |

PP066 : DrDAQ 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.

PP216 Magnetic Induction Kit
|
|
The Pico Magnetic Induction Kit provides a simple and effective method for students to investigate the concepts of Faraday's laws of electromagnetic induction. A small bar magnet is dropped down the tube and, as it passes through the coil, an electromotive force (emf) is induced. The output pulse can be viewed using a Pico PC Oscilloscope, a DrDAQ Data Logger or most other types of digital storage oscilloscopes.
The Magnetic Induction Kit can be used to demonstrate electromagnetic induction, the direction of induced currents and variation of the size of induced emf with velocity. It can also be used as a student-based investigation, either with full instructions or as an open investigation where the students research the concepts.
