How it work:

You may be curious to know exactly how you’ll install these no-holes-needed devices. They have a firm adhesive backing that you’ll need to peel the backing off of to install. Press it to the packaging of the good being monitored, or simply place it inside the carton. You can use tape or cable tie to attach this for repeated use, or find a mounting bracket to be kept inside the truck’s cargo space at all times.

1.Real time temperature report no matter where the vehicle is. Temperature monitoring interval can be adjusted from 30 senconds to hours, The shorter the better.
2.Alert in case the cargo door is openen at unauthorized location.
3.Alert in case the truck leave the departure and arrive at the destination
.4 Ensure the truck run on the designated route by checking history playback

How TPT02 refrigerated truck temperature system work:

The Application

With Eelinktech 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.

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 60°C).
