Wireless humidity probe - AA battery powered

Wireless humidity sensors allow you to monitor the relative humidity of the air in a room or enclosure. Ideal for monitoring humidity in greenhouses, industrial spaces, museums, saunas and humidifiers. They can also be used for residential applications such as mold and dust mite control.

The sensors offer a range of standard sensors with a range of up to over 350m through walls (12 to 14 walls generally). The use of Frequency Spread Spectrum (FHSS) also allows the sensors to have better immunity to interference from other wireless devices.

Superior power management provides the sensors with almost twice the battery life of standard wireless sensors.

• Button cell sensors typically last over 3 years.
• AA and industrial sensors generally last up to 12 years.

The products use the new Encrypt-RF® Security system (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages). Security is therefore maintained at all communication points, gateway sensor, software gateway.

Built-in data storage allows sensors to store data if communication with a wireless gateway is interrupted (power outage, Internet connection cut or out of range). Messages that cannot be delivered will be time stamped and stored in memory (up to the last 512 messages) until communication with the gateway is reestablished, in which case all messages will be transmitted.

Over-the-air updates allow products to be updated remotely if new patches or new features are available.
