STM 550
Solar powered multisensor family
The solar-powered STM 550 Multisensor family integrates temperature, humidity, illumination, acceleration and magnetic contact sensors in a small housing. Since the multisensor has a Near Field Communication (NFC) interface, it can be easily configured and put into operation via an NFC reader, smartphone or tablet.
