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	GMS signal quality indicator that can be mapped to dBm. Refer to sim800l at commands manual
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	Horizontal dilution of precision in 100th
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
