Hawkeye 3-in-1 Monitor & Logger,3-in-1(Temp/Humid/CO2)Sensor

Track Temperature, Humidity, and CO2 Independently of Hydro-X

Not every room needs full equipment control, but almost every room benefits from an independent record of what its climate actually did over a grow cycle. The TrolMaster CM-1 Hawkeye is a stand-alone monitor built for exactly that, displaying temperature, humidity, and CO2 on one screen while calculating VPD automatically so there's no separate lookup chart involved.

Every reading is logged continuously to the unit's internal memory, with the companion mobile app providing remote viewing and alert notifications for anyone who wants to check conditions without walking into the room.

Key Features & Benefits

• 3-in-1 Sensing — reads temperature, humidity, and CO2 from a single onboard sensor probe.
• Automatic VPD Calculation — converts live temperature and humidity readings into a VPD value with no manual math.
• App Connectivity — pairs with the TrolMaster app for remote viewing and alert notifications.
• Onboard Data Logging — stores historical readings internally, with no separate logger required.

Who Should Use the Hawkeye CM-1

Growers who want an independent check on room conditions, a running data log for a grow cycle, or an eye on a space that isn't tied into a full Hydro-X build will get the most from the Hawkeye. It works equally well as a primary monitor or as a second opinion alongside an existing controller.

About TrolMaster

The Hawkeye line sits apart from TrolMaster's Hydro-X control systems as a monitoring-only product, reflecting the Sacramento, California company's approach of selling dedicated tools for growers who don't need full equipment automation. It shares sensor technology with the multi-in-1 sensors bundled with the larger HCS controllers.

Frequently Asked Questions

Can the CM-1 control my equipment directly?

No, the CM-1 monitors and logs conditions and sends alerts, but it does not switch or control devices. For equipment control, TrolMaster's Hydro-X controller line is the appropriate product.

How is VPD calculated?

The CM-1 combines its temperature and humidity readings using a standard VPD formula and displays the result automatically. No manual entry or external chart is required.

Where is logged data stored?

Readings are stored on the unit's internal memory and can be reviewed through the connected mobile app. No separate data logger device is needed.

Does the CM-1 need a separate sensor module?

No, the 3-in-1 sensor is built into the unit itself. No extra sensor purchase is required to begin monitoring.
