‘Telemetry’ is a collective term for the following components that record and transmit information:

Tower Radio

Located on each frost fan tower, a tower radio has two functions. First, it receives temperature information from Canopy Radio and sends it to the Engine Auto-Controller which uses it to determine whether to start or stop the frost fan.

Its second function is to form a network with other frost fans. If it’s a base radio (located on the Base Frost Fan), it will receive data from radios located on Remote Frost Fans. If it’s a remote radio (located on a remote frost fan), it will send data to the base radio.

Canopy Radio

Canopy radios are located around the site (literally in the canopies of trees, vines or whatever is growing there). Their sole purpose is to communicate canopy temperatures to the Tower Radio they are paired with.

B-Board

A device that relays information from the Tower Radio to the Engine Auto-Controller, and from the engine auto-controller back to the tower radio. A b-board is located in all frost fans, not just the base.
