Highly accurate measurements and large memory

HOBO MX Multi-Channel data loggers use Bluetooth technology to transmit indoor monitoring data to mobile devices using Onset's free HOBOconnect app. The HOBO Analog/Temperature/Relative Humidity (RH)/Light data logger and the HOBO 4-Channel Analog data logger support new Self-Describing (SD) sensors, which automatically communicate configuration information to the loggers, making deployment fast and easy.

Simple Setup, Fast Deployment with New Self-Describing Sensors

New Self-Describing (SD) sensors automatically communicate configuration information to HOBO MX Multi-Channel data loggers. Sensor parameters stored inside the SD sensor eliminate the need for programming or extensive setup, supporting fast deployment. Integrated strain relief and a locking jack ensure that the sensor is secured to your data logger, for convenient plug-and-play operation.
