MultiSensor 6 is the foundation of a modern smart home. A 6 in 1 Z-Wave Plus sensor, its perfectly small size hides the technology that powers real-time intelligence for your smart home. Designed and calibrated for precision, the accuracy of MultiSensor 6's sensors varies as little as ±0.2%. In real-time and with real accuracy. MultiSensor 6 will measure MOTION, TEMPERATURE, HUMIDITY, LIGHT LUX, UV, and VIBRATION. Only 1.65 inches in size, can be installed in your home 4 different ways: on a shelf, in a corner, within a wall cavity, or on a wall as a beam sensor. And it can be powered 2 different ways: by batteries or via a USB cable and adapter. A part of Aeotec Gen5 range of Z-Wave products, MultiSensor 6 outperforms all that has come before it. It's built around the latest Z-Wave 500 series chip and firmware, providing a 50% greater wireless range and a 250% faster communication speed over previous Z-Wave products. It has AES 128 bit security encryption built right in.
