Holiday sale ends on 1/18/2017!

This controller contains one humidity sensor and two independent outputs. One output is for humidifier and the other is for dehumidifier. The humidity control can be programmed to vary with time in up to 8 humidity-time steps covering 33 days. It can be used for tobacco/herbal dehydration, sausage curing, etc. By using both humidifying and dehumidifying, the humidity ratio can be controlled at a specific value regardless of whether it is in dry or wet environments. 
This controller is a plug-n-play device. No extra wiring is needed for the humidifier or dehumidifier. Both humidifying and dehumidifying control modes contain simple on/off operation; they are similar to a mechanical humidistat but with much higher precision due to adjustable hysteresis band, precise sensor and digital read out.
This plug-n-play humidity controller is designed for high relative humidity (>85%) and condensing environments, where a slight drop in temperature may cause condensation and could damage other humidity sensors. This controller equipped with one of the most robust humidity sensors on the market. It can be fully recovered even immersed in water.
WIFI feature has been added to this controller. You can monitor the humidity and change any settings on your smart phone, whenever you have a cellular/mobile or WIFI internet access. App-based control provides more user-friendly interface, compared to web based control.  Intuitive graphic interface can provide detailed information for your current & previous humidity. You can also export the graphic data for future analysis (Android only). Both Android and iOS platforms are supported.
