1Product Description
1.1 Overview
The Breeze/Breeze-V/Vivid+ is a multi-purpose LoRaWAN IoT sensor packed into a very small
form factor. The Breeze, Breeze-V, and Vivid+ are all variants in the same sensor family, each
with different sensing capabilities. The Sensor is ideal for monitoring and reporting CO2
concentration, human motion, temperature, humidity, light, and barometric air pressure in an
indoor environment.
The Sensor is also designed to communicate with a 2.9’’ wireless e-Ink BLE Display that allows
room occupants to locally view the latest measurements from select transducers taken in real-
time. The Display will show the most recent CO2, temperature, and humidity measurements
taken from the Sensor, as well as the remaining battery capacity of the Sensor and Display. The
Sensor is designed to only communicate with the BLE Display that is shipped with the Sensor.
All three functional variants are LoRaWAN-capable end-devices that are capable of supporting
Tx/Rx in the following frequency bands as specified in the LoRaWAN Regional Parameters v1.1
[1]: AS923, AU915, EU868, IN865, KR920, RU864, and US915. The variants that support BLE
Tx/Rx operate in the 2.4 GHz band according to the BLE 5.2 specification [2].
Table 1-1 presents the features available in the three functional variants (Breeze, Vivid+, and
Breeze-V).

1.3 Transducer Details
1.3.1 Temperature/Humidity Transducer
The Breeze/Breeze-V/Vivid+ includes a combination temperature/humidity transducer from
Sensirion (SHTC3). It is a small footprint, very low power device. It features operation over I2C
protocol and operates from 0% to 100% RH and -40°C to 125°C with a typical accuracy of ±2%
RH and ±0.2°C. The typical and maximum accuracies specified across the operating relative
1Baseline use case assumes room temperature, LoRa Tx power of 15 dBm, LoRa SF 10, and LoRa BW of 125 kHz.
Optimal battery settings use the default report settings and with dynamic reporting mode enabled. PIR motion
detection is assumed to be very frequent during active hours and very infrequent during inactive hours.
2The sensor provides light intensity measurements, but they are not calibrated in lux. See the Technical Reference
Manual for more details [3].
3No data available from manufacturer on performance outside the range of 15°C to 35°C and 0% to 80% RH.

1.3.2 Ambient Light Transducer
A phototransistor and bias resistor form a light detection transducer on the Breeze/Breeze-
V/Vivid+. The light sensor provides a sufficient window of detection to allow detection of
desired light levels. This window will be tuned as necessary by changing the resistor to give a
detection window corresponding to the light levels to be detected. The output of the light
transducer is an analog voltage that is read by the MCU ADC.
Vishay’s TEMT6200FX1 is a phototransistor specifically designed for ambient light sensing as it
includes a filter to give a response similar to the human eye, thus being capable of detecting
weak light to typical work light conditions.
1.3.3 Barometer
A barometer is included in the Breeze/Breeze-V/Vivid+ in order to measure the barometric air
pressure. TE Connectivity’s MS5607-02BA03 is designed for low power applications while
providing highly accurate measurements. The sensor can operate at full accuracy over a range
of 300 hPa to 1100 hPa, and can communicate over I2C or SPI protocols.
It also includes a temperature sensor in order to correct for the non-linearity of the pressure
measurements over temperature. The pressure accuracy of the sensor is ±2 hPa while
operating between 0°C and 50°C. The barometer also offers an extended pressure range from
10 hPa to 1200 hPa with reduced accuracy. The barometer’s temperature accuracy is ±2°C
while operating between -20°C and 85°C.
1.3.4 CO2Transducer
The Breeze/Breeze-V/Vivid+ includes the Senseair Sunrise to measure the CO2concentration
using non-dispersive infrared (NDIR). It operates over an I2C interface and can measure in the
range of 400 ppm to 5000 ppm with an accuracy of up to ±30 ppm +3% of the reading. This
sensor also features an extended range of up to 10000 ppm with a projected accuracy of
extended range ±10% of the reading.
1.3.5 PIR Transducer
A motion detection feature on the Breeze/Breeze-V/Vivid+ is implemented with a PIR sensor.
Panasonic’s EKM1291111 is specifically designed to be sensitive enough to detect small
movements with a wide field of view of 104° x 104°.
The motion detection system uses a ceiling mount type lens that has an expected coverage area
of 7.7 m x 7.7 m when ceiling mounted at a height of 3 m. Note that this is the theoretical

Breeze/Breeze-V/Vivid+ User Guide T0007805_UG Version 1.2
TEKTELIC Communications Inc. Page 13 of 22
maximum sense range claimed by the transducer manufacturer. The sense range is determined
as the projection of the transducer FoV on the ground, and therefore, should not be interpreted
as the coverage area where the sensor can detect moving people. In general, due to the conical
nature of the transducer FoV, people need to be closer to the sensor to be detected. The
amount of IR radiation from a moving person, which is also impacted by the person’s clothing
or type of skin cover, also plays an important role at determining the detection range.

TEKTELIC Communications Inc. Page 19 of 22
4.4 Push-Button Functions
The Sensor includes two push buttons: one to manually calibrate the CO2transducer, and one
to reset the Sensor. Figure 1-2 shows the location of the CO2calibration and reset buttons
relative to a user facing the Sensor.
4.4.1 CO2Calibration Button
The Sensor features a push-button that can be used to manually calibrate the CO2transducer
when it is exposed to fresh air. The CO2calibration button must be pressed for 2 to 10 seconds,
and 30 seconds after the button is released, the Sensor performs a background CO2calibration
with a target of 400 ppm.
For optimal results, users should ensure that the Sensor is exposed to fresh air for several
minutes before the calibration occurs. It is also recommended that users move away from the
Sensor after pressing the button so as to reduce the risk of an inaccurate calibration. More
information on how to calibrate the CO2 transducer can be found in the Technical Reference
Manual [3].
4.4.2 Reset Button
There is a reset button on the device, that can be pushed by a pin, such as a paper clip. The
button should not be pushed hard. The reset is instant, i.e. the button does not need to be kept
pushed. The reset restarts the microprocessor. All the FW load and configuration parameters in
the Flash are remembered during the reset.
