High resolution and high accuracy, the AR5 Weather Station builds with AR5 Data Logger and any sensors besides the AV-71NR and AV-HFT3. You can choose the sensors up to 8 analog sensors and 3 pulse sensors (AV-30WS, AV-3665). This system also includes the weather protect case, solar power system, tripod. You can select measurement intervals from 1 second to 24 hours. A 30-minute interval will record for about 200 days before the memory is full when you select 10 sensors.
