Sensor Node

Sensor nodes are in stock for the 2025 season. Most orders ship in 1-3 days.  A SapSpy Sensor Node communicates to the SapSpy Sensor Hub (Sold Separately) allowing you to measure vacuum at different locations in your sugarbush. A sensor node can be one of the following configurations:  1) Single Vacuum Sensor with temperature sensor 2) Dual vacuum sensor with temperature sensor 3) Single Vacuum Sensor with Ultrasonic Tank level sensor and temperature sensor (used for a tank and releaser) 4) Single Ultrasonic tank level sensor and temperature sensor (Typically used where an electric releaser pumps to a remote tank where vacuum monitoring is not needed).  In order for SapSpy Sensor Nodes to communicated to the SapSpy Sensor Hub, the Sensor Hub must include an add-on radio option for +$100.  Sap Spy nodes are now capable of Spy Mesh. Spy Mesh allows nodes to repeat a signal in order to significantly increase the distance between end of line vacuum sensors and the sensor hub (Cellular Gate
