The diagram below shows the specific parts of the sensor. Read further to explore the functionality of each part of the sensor.

On/Off switch (1)

The sensor's on/off switch allows you to turn the sensor on, off or perform a hard reset.

To switch the sensor off

• Press and hold down the On/Off switch until the white light shows, then release.

• If not communicating with the EasySense2 app, the sensor will turn off after a period of one

hour of inactivity.

Hard resetting the sensor

• If necessary, attach the sensor to power.

• Press and hold down the On/Off button for at least 8 seconds until the status LED gives a flash

of blue light, then release.

• If the sensor fails to respond, contact Product Support at Data Harvest. Please provide details of:

oThe computer platform it is being used with and the EasySense app’s version number.

oA description of the problem being encountered.

USB Input (2)

• Use to connect to a computer or a charging unit.

• For specific USB or Bluetooth connectivity instructions, please see the 'Connectivity' section of this

documentation.

• For instructions on charging your device, see the section on 'Charging the Sensor'.

Bay for masses (3)

2 x 280g masses are supplied with each cart, these can be stacked here.

3 Position Plunger (4)

The spring-loaded plunger has three positions for firing/release the plunger.

Plunger release button (5)

This is the button to use to fire/release the plunger

Velcro (6)

Each cart has Velcro fitted, for easy connection.

Force sensor, connection for spoked pulley string & magnets (7)

This is the position of the Force Sensor (+/-100N). It is also where the magnets are connected, and

string can be attached to use the spoked pulley. Please see worksheets, which can be found on our

website, for more information.

Interrupt card slots (8)

When using Light Gates/Photo Gates, this is where the double/single interrupt card is fitted.

Unique ID number (9)

All Smart Wireless Sensors are labelled with a unique ID number. This number is used in the

EasySense2 app, so that you can identify each sensor when making a connection wirelessly.

Status Indicator (10)

The sensor features a single status indicator that changes colour and flashes. See the table below for

further information.

Wheels (11)

These are the spring-loaded wheels.

The Status Indicators 

The Sensor and EasySense 

Please make sure that you use the latest release of the EasySense series of software. Both collection and analysis of data is available here, on a variety of operating systems.

Direct Data Logging 

The sensor is designed to work directly with EasySense (as an installed application or PWA). A full compliment of experiments can be run by using the sensor through BluetoothTM or USB. EasySense will support direct logging and data storage when connected as above.  

Remote Data Logging 

The ability to capture data independently (free of a capture station) is done through EasySense’s Remote Mode. 

This facility may be found in EasySense, under Setup. Once the conditions for data collection have been established, the sensor can be set to initiate collection for example, using a rapid press of the power button. Initiation of the experimental data collection by the software is followed by remote detachment; collection is then on the sensor. 

Data gathering is realised by using Setup once again. 

Details are given in the latest EasySense User Guide.
