U-sensor (US)

The CartaSense compact wireless U-sensor monitors temperature and relative humidity in cold-chain and agricultural applications.

CS UsensorPhoto150 550X550

The U-sensor is designed as a one-time-use affordable device. No need for special skills, simply press a button, place it anywhere in a pallet or in the field. Battery powered, the U-sensor functions as a monitor, logger and a wireless repeater. In case of a network disconnection, data is stored in the U-sensor's non-volatile memory until the wireless connection is reestablished. The logged data is then uploaded to the user's communication server.

Utilizing CartaSense advanced mesh technology, the U-sensors strive to find a single or multi-hop path to a gateway. The U-sensors send measurements through nearby sensors automatically, compensating for frequent environmental changes and sensor movement.
