Aranet Radiation sensor QSG v110724

Radiation sensor Quick start guide - Aranet

It is expressed in microsieverts per hour (μSv/h) or millirems per hour (mrem/h). If radiation levels rise, the device uses colors (green, yellow, and red) to alert you, dimming the screen for high values (red level). The default threshold levels are based on scientific recommendations1-4, but you can adjust them as needed through Aranet Home app.

What does Aranet Radiation measure?
Dose rate
describes how strong the ionizing radiation (, ) is at a given moment. It is expressed in microsieverts per hour (µSv/h) or millirems per hour (mrem/h).
If radiation levels rise, the device uses colors (green, yellow, and red) to alert you, dimming the screen for high values (red level). The default threshold levels are based on scientific recommendations1-4, but you can adjust them as needed through Aranet Home app.

Green
Normal background radiation <0.20 Sv/h

Yellow
Radiation above typical background levels 0.20-10.0 Sv/h

Red
Prolonged exposure radiation levels linked to health problems, >10.0 Sv/h

Total dose
of ionizing radiation (, ) encountered during the integration time is expressed in millisieverts (mSv) or rems (rem). Total dose of ionizing radiation is a critical metric for ensuring environmental safety and personal health. If the average rate at which the total dose has been acquired exceeds 0.20 Sv/h, then the upper part of the screen will be dimmed. This reading can be reset from the Aranet Home app or by pushing the mechanical button behind the battery compartment lid. To perform a reset, press and hold the button for 5 seconds.

When a reset is performed, the data will be permanently lost. You should reset this history only if:

The device is passed to you by someone else and the data does not apply to you anymore.

You just want to start fresh, like at the beginning of a new year, as the data will be permanently lost.

Setting up the device
Insert the batteries, and your Aranet Radiation device is ready to go! Please wait a few minutes for the first measurement to appear.

Please wait

Ready to use 4.

CAUTION
 Do not remove the sticker on the back of Aranet Radiation sensor.  Aranet Radiation is not impact-resistant. Exposure to strong
accelerations can lead to erroneous device measurements.  Do not expose Aranet Radiation to high-humidity environments.  Exposing the sensor to X-ray scans, like those at airport baggage
controls, temporarily raises the dose rate reading and total dose readings, which can be disregarded or mitigated by removing the sensor batteries during scans.

Configuration switches
Switches can be found behind the batteries. Use the attached pin to adjust these settings.

Unit switch :

Sv (SI unit, default)

Sv

or rem

LoRa transmission
(non-functional for HOME sensors): On (default) or Off.

rem OFF
Pulse buzzer:
On (default) or Off. When this feature is on, the device beeps every time it detects ionizing radiation event, similar to a Geiger counter. More frequent beeps indicate higher radiation levels.

OFF ON
Bluetooth:
On (default) or Off
