"General overview of the RAIN physical devices:
RAIN is a self-contained unit running an on-board processing unit, the ability to manage multiple external sensors and output(s) for connecting with other RAIN units. Units allows users to keep an eye on remote conditions from a secure web interface through any PC (via Condensate network).
RAIN features analog inputs and one digital sensor port. Up to four digital sensors can be connected by daisy-chaining sensors - this gives an individual network of RAIN devices the ability to monitor larger areas and/or longer distances.
Easily view and log temperature, humidity and dew point along with external sensors over the intranet or the Web, using either a web interface or the RAIN wallet.
Open-source plug and play sensors are also compatible with RAIN devices - including but not limited to, humidity/air, temperature, water/air chemical levels, valve/seal sensor, power failure and more. RAIN's relay port is used to replicate configuration settings across multiple devices at the push of a button.
The web UI reads out an overview of sensor information along with real time environmental data. Measurements are logged allowing users to collect data and easily share that information to the Internet.
RAIN can trigger alerts - for example, if temperature or chemical levels fluctuate over a set value, the user is notified via encrypted messaging."
