- Sensor End
- On/Off Switch
- USB Port
- Status Indicator
- Unique ID Number
Sensor End Connector (1)
Most Smart Wireless Sensors feature an end connector that is specific to the requirements of the device's internal sensor. The sensor's end connector is the direct interface between the device’s internal electronics and your experiment.
On/Off Switch (2)
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 EasySense app, the sensor will turn off after 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 and the EasySense app’s version number.
- A description of the problem encountered.
USB Port (3)
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 have a unique ID number. This number is identified within the EasySense app, so that you can identify each sensor when making a connection.
Microphone
This pack contains one microphone in a stethoscope format. The microphone has a removable protective cover/diaphragm, located on the housing (4.5 cm diameter).
The microphone uses a 3.5 mm jack plug (1.4 m cable length) for connection to the sensor.
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 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.
