Offline Storage

The Binos Monitors have offline storage capabilities where the data is stored on SD cards. Below is the SD card data dictionary.

Number
Name
Description
Example

1

Created_at:UTC

UTC timestamp of when the measurement was taken on the device. This is formulated when there is a GPRS connection.

In case there is GPRS failure to acquire time, a GSM-based time is used and is noted with “LT” local to the timezone

2024-4-25 0:1:57 UTC

2024-4-25 0:1:57 LT

2

RunTime

This is an internally generated count from the microcontroller timers, it overflows and resets at 3850

3

F/W Version

This is the current firmware version running on the device

10

4

DevName

Device name

AIRQO_G5XXX

5

PM1_X_ATM

PM1 particle count from PM-sensor X installed in the device

ATM represents particle count in (µg/m3) under the Atmospheric environment.

This count is what should be considered as the outdoor equivalent of particle concentrations.

“X” in “PM_X_ATM” can be 1 or 2 representing PM-sensor1 or PM-sensor2 installed in the device

6

PM2.5_X_ATM

PM2.5 particle count from PM-sensor X installed in the device

7

PM10_X_ATM

PM10 particle count from PM-sensor X installed in the device

8

PM1_X_CF1

PM1 particle count from PM-sensor X installed in the device

9

PM2.5_X_CF1

PM2.5 particle count from PM-sensor X installed in the device

10

PM10_X_CF1

PM10 particle count from PM-sensor X installed in the device

11

VBat

Device battery voltage measurement in (V) taken from raw ADC measurement

12

SignalQuality

13

Latitude

Latitude coordinate measurement from the GPS receiver in the device

14

Longitude

Longitude coordinate measurement from the GPS receiver in the device

15

Altitude

Altitude measurement in (m) above sea level from the GPS receiver

16

Velocity

Velocity measurement in (ms-1) from the GPS receiver

17

no.Sats

Number of satellites acquired by the GPS receiver

18

HDPD

19

Temp INT

Internal temperature measurement in (℃) taken from an internally placed temp/humidity sensor in the device

20

Humidity INT

Internal humidity measurement in (%) taken from internally placed temp/humidity sensor in the device

21

Temp EXT

External temperature measurement in (℃) taken from externally exposed temp/humidity sensor in the device

22

Humidity EXT

External humidity measurement in (%) taken from the external exposed temp/humidity sensor in the device

23

Pressure EXT

Atmospheric pressure reading in (hPA)

24

Altitude EXT

Altitude reading in (m) above sea level taken from BME280 MEMS sensor

25

Battery Voltage (V)

Battery voltage measurement in (V) taken from a dedicated battery monitoring chip

26

Battery Percentage (%)

Battery charge percentage in (%) taken from a dedicated battery monitoring chip

27

Charge/Discharge rate

Charge and discharge rate of battery derived from battery voltage changes
