CES 2021: Tiny temperature sensor for multiple use cases

Disruptive Technologies, a maker of wireless sensors, has introduced its second-generation wireless temperature sensor and logger at CES 2021.

The sensor weighs just 2 g and is roughly the size of a postage stamp, is wireless and can stick to almost anything with an adhesive backing.

Bengt Lundberg, CEO of Disruptive Technologies told Electronics360, while the first-generation sensor can sense temperature every 15 minutes, the second-generation sensor can be configured up to 30 seconds, amounting to a total of 15 million data points across its lifespan. The sensor also features a 15 year battery life.

“This sensor allows for data to be collected extremely simply and accurately from any asset and exactly where needed, due to its tiny size,” Lundberg said. “Any temperature sensor use case benefits from higher data accuracy, but we’ve seen the most benefits in four main applications: water pipe monitoring for legionella compliance, motor and pump monitoring, cold storage and desk occupancy.”

Additionally, the sensor can be used to catch rapid changes in water temperature and more accurately track temperature and usage of taps in buildings. The sensors can also extend the lifetime of city infrastructure, ensure the temperature is measured accurately in any asset and make buildings and cities more energy-efficient and sustainable, Lundberg added.

Potentially, the sensors could be used to monitor temperature changes in delivery of healthcare items that require refrigeration or food and grocery deliveries.

“So far, out partners have created excellent cold storage applications that have saved up to $1.36 million in food during the pandemic,” Lundberg said. “We have not seen them be used in a delivery setting yet. But applications for the entirety of the cold chain for our temperature sensors are very feasible with the right partner and are certainly a possibility in the near future.”

Another possible use case could be in the smart home or in smart buildings because the sensor is small enough to fit inside of a frame of a door or window, picking up the granular temperature changes. This could potentially be used to alert users to an open window or door either wanted or unwanted.

Occupancy in the workplace

Lundberg said one of the more popular applications for the temperature sensor is occupancy in the workspace. A temperature sensor placed under desks could measure the difference between when a person sits at a desk versus when the desk is unoccupied.

“This has proven essential during the pandemic to ensure compliance with regulations,” Lundberg said. “It has also helped our customers understand employee working styles, how to accurately measure and allocate space capacity, increase revenue potential and ensure employees have the right space for their needs.”

Furthermore, the sensor can measure the overall temperature in the workplace to help managers optimize energy use by up to 31%, reducing monthly electricity costs in some cases and reducing the company’s carbon footprint by 30%.
