The Solution & How it Works:

A Battery Powered Portable Temperature Monitoring Device

Packaged in an IP67 waterproof enclosure with integrated GPS and cellular antennas, equipped with an 7800 mAh rechargeable lithium back up battery and an external digital temperature sensor with +/- 0.5˚ C, +/- 0.9˚F accuracy, the Piccolo TMX+ monitors the temperature in a closed area and transmits data periodically to the server.

Easy Installation

Easily deploy the Piccolo TMX by placing the device in the desired area to start monitoring the temperature. The Piccolo TMX can also be ordered with a wire-harness for a fixed installation when connection to external power is available.

Temperature Monitoring

Once placed in the refrigerated area, the Piccolo TMX is normally in deep sleep mode configured to wake up once every XX minutes, read the temperature with the current GPS position and send it with a time stamp to the server.

Battery Life Preservation

To preserve battery life, the Piccolo TMX can be set to accumulate temperature readings. In this case, the TMX will wake up every XX minutes (for example every 5 minutes), read the temperature with the battery life and time stamp, store it and send all accumulated readings with their respective time stamps to the server every YY minutes (for example every 60 minutes).
