Detailed Product Description

TPT02 wireless temperature monitoring and gps tracking systems which are cost effective and cloud based for wireless end-to-end cold chain monitoring. The GPS temperature monitors vehicles, cargo, their condition and environment automatically.


You will have full visibility and traceability to your supply chain and operations. The system provides real-time temperature and location information throughout the transport and storage time. If temperatures limit values are exceeded, the service automatically sends alerts on your mobile and email. The iphone Android app and web based reporting enhance your customer service, product quality and business profitability.



Diweitrack TPT02 has a complete suite of sensors designed specifically to ensure your high dollar or time sensitive cargo is being handled safely. Hover over or click an icon below to learn more about each sensor.


LocationLocationTPT02 devices can determine location through GPS, Assisted GPS, Wi-Fi, and Cellular Location-Based Services (LBS)
Temperaturetemperature monitor TPT02 has an on-board temperature sensor for ambient temperature measurements. It also is capable of working with an optional external temperature probe which allows for extended temperature ranges and use in harsher environments
HumidityHumidity monitoringMany products are sensitive to, and can be damaged by, changes in relative humidity. TPT02's are able to sense ambient RH.
Lightlight monitorMeasuring light is a valuable indicator to alert you when a box or container is opened (thus letting in light).
InfraredinfraredMeasuring infrared light is a valuable indicator to alert you when a box or container is opened in the dark.
Shockshock detectionShock detection can alert you to sudden impacts that an asset is subjected to such as handlers tossing products or otherwise handling them roughly.
DropDrop detectionTPT02 devices can Drop detection can alert you immediately if a product is dropped or falls.
Vibrationvibration For some types of cargo, excessive vibration can be damaging and indicative or poor care and handling. The PT300 includes a vibration sensor that can alert you when conditions cause concern.
Motionmotion detectionMotion detection has many uses, including the ability to put the unit to sleep to extend battery life and minimize data and network connection charges.
SignalsignalTPT02 Device can measure and record the strength of the mobile phone signal received by the device from the cellular network. Also  referred to as RSSI or “Received Signal Strength Indication
BatterybatteryTPT02 devices have a battery level sensor which provides an accurate indication of battery capacity remaining.


The Need For Monitoring Refrigerated Trucks Temperature
Without Refrigerated trucks, it would be nearly impossible for transporting temperature sensitive goods. It is a mandate to maintain the temperature when transporting temperature sensitive goods to reduce wastage and maintain compliance.


Reduce Wastage

Reduce Wastage


35% of the manufactured goods are wasted during transportation due to improper storage of temperature sensitive goods

Be Proactive

Be Proactive


Truck companies can get alerted if there is a temperature failure. So, they can take proactive measures to avoid any wastage.

Monitoring temperature and location History



Truck companies need to log the refrigerated truck’s temperature at regular intervals for compliance and regulatory purpose.

Temperature Monitoring Solution for Refrigerated Trucks


The Application


With Diweitrack Web and mobile application can give the assets temperature in real time. The application gives a birds eye view of all refrigerated trucks that are monitored – their location, temperature, speed, last pit stop etc. in a simple map or table view. The temperature along with location history can be downloaded as weekly, monthly report.

1. Switch on the device

• Press the green power button for 3 seconds

• A slow blinking blue light says device has found a network connection

• A slow blinking red light says low battery (device can be charged via microUSB)


2. Attach the device to goods

• For first time use, gently peel the backing away from the adhesive on reverse of device

• Press device firmly against the exterior packaging of goods being monitored or place inside cartons

• For repeated use, the device can be attached to goods with tape, string or cable tie (avoid covering the light sensor)


3.Charging the Device

•For best results, the device should be fully charged before first use.

•Once fully charged, the device should maintain its charge for about 2 months.

•A continuous red light during charging means the device is fully charged.

What’s the purpose of the Red LED on the device?

The Red LED represents battery condition.

When the battery is low, the red light will blink slowly.

While being charged, the red light blinks rapidly.

Once fully charged, the red light glows continually.

What’s the purpose of the Blue LED on the device?

The Blue LED represents wireless connectivity.

When the device is first switched on, the blue light will blink rapidly, searching for a mobile phone signal.

When a signal is found, the blue light will blink slowly.

The blue light will switch itself off after 2minutes to conserve the battery.

When you switch the device off, the blue light will glow continually before shutting down.


How do I charge the device?

The battery should be charged before each usage. The device will only be partially charged when you first receive it.

The battery can be charged via the charger or via a USB cable from your laptop. While being charged, the red light on the device will blink rapidly.

Once fully charged, this red light will glow continually.

The battery level of a device can be monitored via the web application. An alert notification will occur if the battery levels drops too low.

These alerts can be configured via the Alert Rules section of the web application.


Why is device location only approximate?

The device determines location via LBS cell tower triangulation and, unlike GPS, requires no satellite visibility.

Accuracy will vary depending on the number of cell towers in the area. In large cities, typical accuracy is +/-500m. In remote rural areas, the accuracy may be +/-3000m.


How accurate is the temperature sensor?

The temperature sensor is accurate to +/-0.5°C for typical cold chain temperatures (-20°C to 20°C).
