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

Track Temperature, Humidity, and CO2 in Real Time

The TrolMaster CM-1 Hawkeye is a stand-alone climate monitor that displays temperature, humidity, and CO2 levels on one screen, while calculating VPD automatically so you always know how close your grow space is to its target range.

Data logging runs continuously to an internal memory, with options to review readings through the companion mobile app, making the Hawkeye useful for tracking conditions over an entire grow cycle.

Key Features & Benefits

• 3-in-1 Sensing — Reads temperature, humidity, and CO2 from a single sensor probe.
• Automatic VPD Calculation — Converts temperature and humidity readings into a live VPD value.
• App Connectivity — Pairs with the TrolMaster app for remote viewing and alert notifications.
• Onboard Data Logging — Stores historical readings for later review without a separate logger.

Who Should Use the Hawkeye CM-1

Growers who want an independent way to verify room conditions, log historical data, or keep an eye on a space that isn't tied to a full Hydro-X control system will find the Hawkeye CM-1 useful as a dedicated monitoring tool.

Monitoring Only, No Device Control

The Hawkeye CM-1 is built for monitoring and alerting rather than equipment control. For a unit that also manages humidifiers, dehumidifiers, lights, or CO2 equipment based on sensor readings, look to the Hydro-X controller line instead.

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.

How is VPD calculated?

The CM-1 combines its temperature and humidity readings using a standard VPD formula and displays the result automatically, with no manual entry required.

Where is logged data stored?

Readings are stored on the unit's internal memory and can be reviewed through the connected mobile app.

Does the CM-1 need a separate sensor module?

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