  • Page 9: Overview

    The Comfort/Vivid are both multi-purpose LoRaWAN IoT sensors packed into a very small form factor. The Comfort and Vivid are both variants in the same sensor family, which differ in some of their sensing features. Comfort/Vivid sensors are ideal for monitoring and reporting temperature, (ambient, remote through a probe, or MCU), humidity, light, shock, and open/closed doors and windows in a home/office environment.

  • Page 27: External Connector Configuration

    The Sensor features an external connector that allows users to connect an analog or digital external sensing probe. Only the Comfort model is equipped with an external connector. This connector can be configured as either a digital input (having only two values or states of “open” and “closed”), or analog input. The input mode (digital or analog) is determined by bit 7 of register 0x2D (see Table 4-9).

  • Page 31: Accelerometer Configuration

    Acceleration events are reported with the acceleration magnitude, acceleration vector, or both. Here “impact” generally refers to a Sensor motion event (i.e., not necessarily an impact to the Sensor). Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.

  • Page 32: Table 4-11: Accelerometer Configuration Registers

    If the impact alarm event threshold is enabled (register 0x34, bit 0), an impact alarm is always raised (reported) when the impact alarm event threshold (register 0x30) is exceeded, and is cleared after an impact alarm event grace period (register 0x36) elapses without any impact alarm events (see Section 4.2.5.7). Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.
  • Page 33 Note that if a threshold configured in register 0x30 or register 0x31 is equal to or greater than the configured measurement full scale (2 g, 4 g, 8 g, 16 g), then the corresponding event (impact alarm or acceleration event) will never be triggered. Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.
  • Page 34 Event Debounce Time, after an acceleration event is registered. This is to prevent a single acceleration event from being transmitted as multiple events. The minimum debounce time is 1 (one) sec. A value 0 (zero) is invalid and ignored. Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.

    This feature is to allow customers to filter out short impact events, while still allowing longer impact events to be reported. Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.

    Note that the threshold window here is defined as the open interval “(Low Threshold, High Threshold)”, not e.g. the closed interval “[Low Threshold, High Threshold]”; i.e. even if the transducer value is equal to Low Threshold or High Threshold, the Sensor is considered to have left the threshold window.

  • Page 42: Motion Transducer Configuration

    Note: The PIR transducer is designed to detect motion so if a room is occupied but the occupants are not moving, the sensor may report “No Motion” after the Grace Period (see Section 4.2.8.1) expires. Table 4-18 shows a list of motion transducer configuration registers. All the registers have R/W access. Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.

  • Page 43: Table 4-18: Motion Transducer Configuration Registers

    4.2.8.1 Grace Period The Grace Period determines how long the Sensor waits before the previously reported PIR motion event is considered clear. For example, a Grace Period of 5 (five) min results in the sensor transmitting “Motion Comfort/Vivid TRM T0006338_TRM Version 3.1 TEKTELIC Communications Inc.
