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


1. Sensor End Cap

2. Status Indicator

3. On/Off Switch

4. USB port

5. Unique ID Number


Sensor End Cap (1)

Most Smart Wireless Sensors feature an end cap that is specific to the requirements of the device's internal sensor. The sensor's end cap is the direct interface between the device’s internal sensor and your experiment.

Status Indicator (2)

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

On/Off Switch (3)

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 it is not communicating with the EasySense 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:  
    • The computer platform it is being used with and the EasySense App version number.
    • A description of the problem being encountered. 

USB Port (4)

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'. 

Unique ID Number (5)

All Smart Wireless Sensors are labelled with a unique ID number. This number is used in the EasySense app, so that you can identify each sensor when making a connection wirelessly.


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.
