MSR - Model 385WD - Data Logger - Datasheet

The MSR385SM transmitter modules record temperature profiles, humidity and pressure by means of sensors and send the measured values to the MSR385WD data logger in the 868 MHz ISM band, which can be used without a licence. Due to their thermal resistance, the transmitter modules – depending on the type of case – facilitate applications even at high operating temperatures of up to +125 °C. Thanks to their compact case, they can also be placed in locations that are difficult to access, for instance in working machines or inconspicuously in display cabinets of museums. The optimised power management ensures that – depending on the frequency of measurements and radio transmissions – the power supply to the miniature transmitter modules is warranted for up to five years.
