Wireless Temperature Tag
Albert (our 3D printing expert) is designing enclosures for our wireless temperature sensor tags. We have gone through a few 3D printed versions already. The enclosure material is ABS.
These tags are suitable for sensing temperature indoors (warehouses, cold chains etc). You can see the sensing element (a thermistor) sticking out of the tags. These tags are powered by two coin cells (3V CR2032) which can last more than three years assuming 1 transmission every 5 minutes. The tags have an internal PCB antenna but also have a U.Fl connector for an external whip antenna.
The tags operate in the 865-867 MHz license free band in India.
