General Description

The Power-over-Ethernet (PoE) Humidity (RH) Sensor accurately monitors the relative humidity of the air within a room orenclosure. Additionally, the iProTAACS Online Sensor Monitoring and Notification System also calculates dew point and absolute humidity and stores all these data points in the online system where the data can be reviewed and exported as a data sheet or graph. Notifications can be set up through the online system to alert the user when defined thresholds have been met or exceeded.


  • Power-over-Ethernet ready (injector hardware required)
  • Embedded LEDs for transmission & online condition indicators
  • 50,000 sensor message memory (non-volatile)
  • Modbus TCP & SNTP v1 interface capabilities
  • No PC required (managed through apps and smart devices)
  • Remote update capable w/automatic updates
  • Works with iProTAACS Cloud and Enterprise software applications
  • Optional 5V DC power supply available

Example Applications

  • Greenhouse Humidity Monitoring
  • Art gallery and museumenvironmental monitoring
  • General weather andenvironmental monitoring
  • Agriculture environmentalmonitoring
  • Humidor monitoring
  • And Many More

Commercial Grade Sensors

ProTAACS commercial-grade sensors are designed for applications in ordinary environments (normal room temperature, humidity, and atmospheric pressure). Do not subject these sensors to the following, as these environmental aggressors could degrade the device and its performance, leading to failures and burn-out:

  • Corrosive or deoxidizing gas, e.g., chlorine gas, hydrogen sulfide gas, ammonia gas, sulfuric acid gas, andnitric oxides
  • Volatile or flammable gas
  • Dusty conditions
  • Extremely low or high pressures
  • Wet or excessively humid locations
  • Places where saltwater, oils, chemical liquids, or organic solvents are routinely present
  • Applications/locations prone to excessive or strong vibration
  • Other sites where similar hazardous conditions exist

Use these products within the ProTAACS-specified temperature range. Higher temperatures could deteriorate both the product and its functionality.
