How We Help

Measure Relative Humidity

Adopt responsive and stable humidity sensor to provide accurate and reliable readings of relative humidity (RH), minimizing drift and ensuring consistent performance over time.

Auto Maintain Target Humidity

By setting target humidity range, the INKBIRD humidity controller will automatically switch between humidifier and dehumidifier when the humidity deviates from the setpoint.

Alert When Abnormal

Alarms will be triggered when humidity levels exceed or fall below predefined thresholds, or if the humidifier, dehumidifier, or humidity sensor fails. The WiFi version can send alerts via the app.

What Our Customers Say

I'm quite pleased with this unit which seems to work as advertised and is built sturdily. The controls to set humidity and other functions are straightforward and well-described. The unit has to AC output plugs, one to plug in a humidifier, the to plug in a dehumidifier. Theoretically, one could put a humidifier and dehumidifier in the same room and let them duke it out.

My wife runs 3 egg hatchers and our Inkbird controller makes environmental control for these a breeze. This unit is very easy to program, very accurate and dependable. The alarm system that notifies us when the humidity is outside our set parameters relieves from having to check the hatchers multiple times a day.

I purchased this to maintain humidity in my mushroom fruiting chamber. The controller maintains the humidity level where it needs to be without running the humidifier constantly. It maintains the levels right where they need to be for mushrooms without leading to water buildup in the chamber from running the humidifier constantly.

Simply put, I use this to automatically control a dehumidifier in my basement to keep a consistent and comfortable humidity. As the basement is finished and doubles as my home gym, it's a must have. The sensor mounts on the wall and send accurate. When the humidity gets to high it switches on the dehumidifier.

Frequently Asked Questions

How does INKBIRD humidity controller work?

INKBIRD humidity controller works by continuously measuring the relative humidity in the environment with its built-in sensor, and comparing them to your set target. If the humidity drops too low, the controller will activate a humidifier. Conversely, if the humidity exceeds the setpoint, it will switch on a dehumidifier.
How often do I need to calibrate a humidity controller?

Calibration needs can differ, but it's generally recommended to calibrate your humidity controller at least once a year or whenever you notice discrepancies between the controller readings and your actual humidity levels. In addition, if the sensor is being used in a harsh environment, you might need to calibrate it more often.
How to calibrate a humidity controller?

If you've got a humidity sensor that is recently calibrated, you can take advantage of it. But if not, here's what to do:

  1. Put salt in a small container.
  2. Add just enough water to moisten the salt without fully dissolving it.
  3. Seal that container inside an airtight one and leave it for about a day.
  4. After 24 hours, check the humidity reading. If it's not at 75% RH, adjust the sensor to read 75% RH.
What humidifier/dehumidifier can I use with INKBIRD humidity controller?

You can connect various humidifiers and dehumidifiers to the INKBIRD humidity controller, as long as they are compatible with the controller's voltage and output.
