ZigBee Multi Sensor for Temperature, Brightness, Motion Detection

ZBS-121 - ZigBee



  • Precise temperature measurement (up to 0.3 °C; resolution 0.1°C on demand)
  • Brightness
  • Integrated PIR motion detector
  • Presence Detection / Alert (avoids continiously sent motion detection telegrams)
  • Battery-Low message
  • Firmware upgradable via ZigBee network
  • OGEMA-Driver on demand (Open Gateway Energy Management Alliance)

Ultra low power operation: Getting rid of useless telegrams and empty batteries

Though the device can sample in quite small cycles, a couple of µA (thousandth of a Milliamp) are enough for a long-term and reliable operation. After the internal sampling / measurement all internal sensors are cut off from the power supply leading to absolute zero current consumption. Flexible configurable thresholds (high / low) for all sensors will lead to immediate alarm telegrams only in case of violation. This approach combines almost realtime data with the longest battery lifetime.

Long time before the battery gets empty, "Battery-Low" messages are sent in order to prevent connection loss and ensure reliable operation.
