* For best accuracy, recommended operating range is 10°C to 40°C (50°F to 104°F) and 20% to 60% RH (non-condensing).
Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.
** Bluetooth pairing disabled, LoRa radio disabled, data transmission at a 10 minute interval.
Aranet4 is not impact resistant!
Do not use the device in high humidity environments (greater than 85%)!
Do not leave the device in direct sunlight!
