How it works

The sensor provides Radon concentration level every hour. Thus, the first valid data is available 1 hour after powering up.
Radon concentration data may be affected by severe variations, according to the high variability that Radon has in short-term periods. Thus, in order to obtain a more accurate representation of the data, it is recommended to use a Mean value.
The Mean will represent the actual Radon presence in a much better way than the instantaneous value. For a short-term analysis, it is recommended to use a 3 hour mean. For a long-term analysis, it is suggested to calculate a 12 hour mean.
The sensor sends out the instantaneous Radon level via Asynchronous communication (UART) each hour. Moreover, it is possible to communicate simple tasks to the sensor:
• Polling systems can interrogate the sensor simply by sending the ‘r’ character (ASCII: 114d, 72h). OEM will answer back with the last calculated value.
• The sent data can have 2 different formats: ‘char’ and ‘numeric’. For system startup, always set it to ‘char’. That can be changed by sending the ‘c’ (ASCII: 99d, 63h) or the ‘n’ (ASCII: 110d, 6Eh) character respectively for ‘char’ and ‘numeric’ format. No ACK or positive feedback is sent back.
• It is possible to perform a hard reset of the system via software. That will Kill each process and will restart the system from the beginning. It is achievable by sending the ‘k’ (ASCII: 107d, 6Bh) character. Still, no ACK or positive feedback is sent back.
