1101 - Wireless Fast Response Temperature Sensor

| Revision: 3.0 | DS168

Introduction

Thank you for purchasing the Smart Wireless Fast Response Temperature Sensor. We pride ourselves

on producing high quality products that meet with the demands of the busy classroom environment. If

you have any problems using this sensor, please read this documentation in full before contacting the

Data Harvest support team.

Overview

The Smart Wireless Fast Response Temperature sensor features an exposed thermistor bead. Heat

will enter the thermistor bead directly, making it sensitive to quick and small changes in temperature.

The flexible nature of the sensor lead allows it to be threaded into apparatus or fed through adjacent

surfaces, for example the door seal of a fridge.

It is ideal for determining changes in skin temperature, measuring air temperature in tight spaces (for

example in a syringe) or when some flexibility is required.

The Smart Wireless Fast Temperature sensors are USB and Bluetooth compatible. Using Bluetooth, a

sensor can connect to mobile devices, tablets, laptops and desktops.

The sensors are supplied with a mini USB lead (1 m standard A to standard mini B) and calibrated in

degrees Celsius ( C) as the default range.

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.

The Status Indicators (2)

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

further information.

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 EasySense2 app’s version number.

oA 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

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

| Revision: 3.0 | DS168

Connectivity

The sensor is both USB and Bluetooth compatible. Install the EasySense2 app, if it is not already on

your device. For details of how to operate the EasySense2 app, please refer to the EasySense2

documentation.

USB Connectivity

Quick Steps

1.Connect the sensor to the computer’s USB port using the USB cable supplied.

2.The computer will automatically detect a new device and depending on your operating system, will

install any applicable device drivers.

3.Start EasySense 2 app.

4.Within the EasySense2 app, the Devices icon will change to green to show that the sensor is

connected, and the status light on the sensor will also turn green. 

5.Begin your practical investigations.

Bluetooth Connectivity

Using Bluetooth, the sensor can wirelessly connect to mobile devices such tablets and mobile phones,

as well as desktop or laptop computers, giving students the ability to run experiments independently

without being tethered to a device.

See the EasySense2 app user manual system requirements for further details.

Quick Notes on Bluetooth Connectivity

Only use with the EasySense2 app, you do not need to pair the device. If paired, the sensor will not be

available to the EasySense2 app.

Computers or devices will need to support Bluetooth Low Energy (BLE). For further information refer to

the instructions provided for the EasySense2 app.

Quick Steps

Short press the on/off switch to turn the sensor on, blue LED will flash.

2.Open the EasySense2 app.

3.Select the Devices icon.

Select your sensor from the list of available sensors to connect to the device. Your sensor is

identified by its unique ID in the list.

5.Click on connect at the side of your sensor in the list.

The Devices icon will change to green and the status light on the sensor will flash green to indicate a

connection has been established.

7.Begin your practical investigations.

Charging the Sensor

The Smart Wireless sensors are fitted with a rechargeable lithium-ion battery and can be charged via

the USB port. Use the supplied USB lead to connect the sensor either directly to a USB port on your

computer, a powered USB hub or a USB mains charger that outputs 5 V at 500 mA or more.

A full charge can take up to 4 hours.

Additional Information

Whenever the sensor is connected to the USB port on the computer or to a USB mains charger (output

5 V at 500 mA or more), it will automatically recharge the battery (LED status flashing white).

When connected to a computer, the computer should be turned on and not in sleep or standby mode,

as the battery may drain instead of charge.

The sensor will stay awake for 60 mins when Bluetooth advertising (LED status flashing blue).

Lithium-ion batteries are ‘memory-free’ and prefer a partial rather than a full discharge. Constant partial

discharges with frequent recharges will not cause any harm. Frequent full discharges should be

avoided whenever possible. Ideally the sensor should be stored at about 40% or more charge.

The speed at which a lithium-ion battery will age is governed by both its storage temperature

(preferably less than 40 C) and state-of-charge.

Firmware Updates

Occasionally Data Harvest may release updated firmware which will contain improvements or new

features.

Updates will take place when you connect your sensor to the EasySense2 app. You will be given the

option to decline an update.

Updates can be performed over USB or Bluetooth and will typically take less than one minute. Updating

firmware over USB will be quicker than Bluetooth.

Do not disconnect the sensor, or power off during the update.

If you have a wireless connection to the EasySense2 app, the sensor will have to be reconnected after

performing the update.

1101 - Wireless Fast Response Temperature Sensor

| Revision: 3.0 | DS168

Usage Information

Temperatures higher than 125 C (257 F) or lower than -40 C (-22 F) will damage the sensor.

This Temperature sensor is NOT recommended for use with laboratory chemicals.

Do NOT put any part of the sensor into a direct flame or onto a hot plate.

The total length of PVC cable and thermistor wire is approximately 39 cm. It is made up of about 17

cm of PVC cable, approx. 3.5 mm diameter, with approx. 4 cm of heat shrink tubing linking the

cable to the thermistor wire. The length of thermistor wire and bead is approx. 18 cm long, with a

diameter of approx. 2 mm.

The electronics in the Smart Wireless module of the sensor have a working range of 0 to 40 C.

Position the sensor so that this part of the sensor is kept away from the source of heat. Take steps

to protect against excessive steam.

The Smart Wireless module is not waterproof; it has an operating range of 0 to 95% RH (non-

condensing). Do not place the sensor in an environment in which high humidity levels are possible,

as this may result in damage or malfunction.

Do not submerge the sensor. Clean the Smart Wireless module using a damp cloth; do not

immerse in water or detergent.

If the sensor has been left in the cold, let it warm to near room temperature before waking it from

sleep.
