Inkbird - IHC 200 WIFI Humidity Controller

Control Humidity from Your Phone

The INKBIRD IHC-200-WIFI gives you direct control over humidifiers and dehumidifiers through a free mobile app.

Check current humidity, change your settings and monitor conditions from your phone without repeatedly walking back to the room, tent or enclosure.

The controller connects to 2.4 GHz Wi-Fi only and supports IEEE 802.11b/g/n networks.

Automatic Humidification and Dehumidification

The IHC-200-WIFI includes separate outputs for humidification and dehumidification equipment.

Set your preferred humidity range and the controller automatically switches between the two operating modes as conditions change.

Connect compatible equipment such as:

• Humidifiers
• Dehumidifiers
• Ventilation fans
• Other humidity-control equipment within the controller’s electrical limits

Once configured, the controller works automatically to keep conditions within your selected range.

Built for Grow Rooms and Greenhouses

Humidity can change quickly after watering, when lights switch off or as plants become larger.

Use the IHC-200-WIFI to help manage:

• Grow tents
• Indoor gardens
• Greenhouses
• Propagation areas
• Seedling rooms
• Drying and curing spaces
• Mushroom-growing areas
  

The controller can activate a humidifier when conditions become too dry or switch on a dehumidifier when humidity becomes excessive.

Reptile, Amphibian and Small-Animal Enclosures

Maintain more consistent humidity in terrariums, vivariums and other controlled habitats.

The controller can help manage equipment used for:

• Reptiles
• Amphibians
• Tropical enclosures
• Hedgehog rooms
• Incubation areas
• Other humidity-sensitive animal environments

The IHC-200-WIFI monitors and controls connected equipment, but it should not replace proper thermostats, equipment safeguards or species-specific care.

Storage, Fermentation and Equipment Protection

Excessive humidity can damage products, encourage mould and create problems for sensitive equipment.

Useful applications include:

• Basements and crawl spaces
• Wine and food-storage rooms
• Fermentation chambers
• Cigar storage
• Instrument and collectible storage
• Server and networking rooms
• Workshops and garages
• RVs, cabins and seasonal spaces

Phone Monitoring and Adjustment

Through the compatible INKBIRD app, you can:

• Check current humidity
• Change humidity settings
• Monitor the controller remotely
• Adjust control limits
• Silence compatible alarms
• Manage conditions without constant manual checking

Remote app functions require the controller to remain connected to a compatible Wi-Fi network with internet access.

High- and Low-Humidity Alarms

The controller can trigger an alarm when:

• Humidity exceeds the selected high limit
• Humidity falls below the selected low limit
• Humidity reaches the controller’s alarm threshold
• The humidity sensor develops a fault

The alarm can be silenced using the physical controls or through the mobile app.

Humidity Range and Accuracy

• Measurement range: 10% to 99% RH
• Relative-humidity accuracy: approximately ±3% to ±5% RH

Actual performance may vary according to sensor placement, airflow, condensation and environmental conditions.

Humidity Calibration

The IHC-200-WIFI supports humidity calibration.

This allows the displayed reading to be adjusted when compared against a trusted reference instrument or when installation conditions create a consistent measurement offset.

Output Delay Protection

Built-in output-delay protection prevents connected equipment from being switched on and off too rapidly.

This helps reduce unnecessary cycling and provides additional protection for the connected equipment and the environment being controlled.

Important Information

• Supports 2.4 GHz Wi-Fi only
• Does not support 5 GHz-only Wi-Fi networks
• Includes humidification and dehumidification control modes
• Automatically switches between control outputs
• Connected equipment must remain within the controller’s rated electrical capacity
• Avoid placing the sensor where it may be exposed to direct water, condensation or extreme localized airflow
• This controller regulates humidity only; it does not control temperature unless paired with separate equipment
