Sensors
The sensor leads
There are four sensors leads supplied with V-Hub, two long and two short. These are used to connect
Smart Q sensors to the inputs on V-Hub.
The plug-in sensors
Smart Q Sensors are available to purchase separately and are not supplied with V-Hub.
Sensors can be divided into two main types:
1. Analogue - used to measure physical quantities such as temperature,
sound, light, pH, etc.
2. Digital - switch-type sensors for measuring ON/OFF
conditions e.g. Light gates and Timing mats to
calculate time, speed and acceleration.
Please contact your supplier or the Data Harvest website (www.data-harvest.co.uk) for up-to-date
information on Smart Q sensors.
Plug the Smart Q sensors into the shaped input sockets on the top of the logger using the leads
supplied with the logger. When a sensor is connected it will automatically be detected.
Sensor inputs 1 and 2 are dual labelled as A and B. These inputs are for Timing operations when
digital sensors must be connected to either input 1:A or input 1:A and 2:B.
Selecting the sensor range
Some of the internal sensors in V-Hub
