Product Description – Humidity / Psychrometric Sensor Module

The Humidity Module is Evergreen Telemetry’s intelligent, all-in-one psychrometric sensor—built for technicians who demand fast, accurate environmental readings without the mess of traditional sensors.

No wet sock. No guesswork.
This smart humidity module directly measures temperature (dry bulb), relative humidity (%RH), and barometric pressure, then instantly calculates:

• Wet-bulb temperature

• Enthalpy (h)

• Humidity ratio (w)

• Grains of moisture (gr)

• Specific volume

All readings are wirelessly streamed to your Wrist Reporter for real-time decision-making in the field. Whether you're fine-tuning HVAC systems, managing critical spaces, or troubleshooting comfort complaints, this compact module puts complete psychrometric data at your fingertips—faster, easier, safer.
