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 Gateway). Videos and additional instructional content will be updated in Q4 of 2022 discussing this new and exciting functionality.

A single sensor hub can service many sensor nodes (currently up to 40). The recommended maximum number of hops between a sensor hub and sensor node is 4. The expected distance between two sensors nodes is estimated at ~1500' - 2500' through a typical sugarbush. Line of sight, sensor nodes can reach 3 miles+ between two nodes. It is recommended to use a dedicated Sensor Hub per sugarbush location and use that particular Sensor Hub to service all sensor nodes in the local sugarbush.

Control Node

$475.00

A SapSpy Control Node communicates to the SapSpy Sensor Hub (Sold Separately) allowing you to control a relay module, measure vacuum, tank level and temperature in different areas of your sugarbush. A control node is typically used at a secondary collection station or another location in the sugarbush where you need to turn a motor on/off, open/close a solenoid valve, or any number of applications.

Control nodes will require 5V power via a USB cable. This keeps them "awake" 24/7 always listening for commands. For the 2025 season, control nodes should be within direct communication of a sensor hub.

Control Nodes will be a limited release for the 2025 season. Customers who purchase a limited release version will have an opportunity for a free upgrade if hardware changes are required.

Metering Node (Pulse Counter)

$400.00 $360.00

A SapSpy Metering Node keeps track of the total sap collected in a sugarbush at each electric releaser. The metering node tracks the total gallons or liters pumped at every 5 minute interval. Within the Sap Spy web app, we then calculate and visualize the following:

Total gallons for the season
Total gallons/tap for the season
Gallons/reading
Gallons/Hour
Gallons/Day
Gallons/Tap/Day

This data helps you track your total production for the season helping you optimize your operation. Data is maintained year over year for ongoing seasonal comparisons.

Metering nodes will be a limited release for the 2025 season. Customers who purchase a limited release version will have an opportunity for a free upgrade if hardware changes are required.

A Sap Spy metering node is simply a pulse counter. It is universal and operates with any water meter that produces a pulse output. If you already have a water meter with pulse output capability, there is no need to replace it. Simply use this node directly.

If you don't already have a metering node, one can be purchased separately.

Pulse counting can also be used to count the total number of dump cycles from a mechanical releaser allowing you to track total volume of sap processed and average time taken between dump cycles. This requires a magnetic reed switch also sold separately.
