Woooooooow very very good and very good product im so happy and packaging super
I have make a remote control car
Product worked well for my Linux pc, no drivers needed, simple installation.
ZFX-13001 12V DC High Precision Capacitive Humidity Controller
Couldn't load pickup availability
The ZFX-13001 12V DC high-precision digital humidity control controller is with wide humidity measuring range and controlling range and comes with a humidity controller sensor probe with cable. The humidity sensor uses a high-precision capacitive faster chip which has the advantage of high accuracy to reflect. The humidity measuring range is 1 percent - 99 percent RH and the control range is 1 percent RH. Humidification and dehumidification can be set through the menu, the parameters have been set for the power outage permanent memory function.
The digital humidity controller can set a high or a low humidity limit when the humidity is beyond the compass of limits, it will humidify or dehumidify automatically With the humidity sensor, uses a high precision capacitive chip, high accuracy, and wide humidity measuring range. With a large and clear LED display for better readability.
Anti-interference control: When the temperature control mode (code is HC) was H, eg. the setting control humidity is 50% RH, slewing range of temperature is 5% RH, when the environment humidity setting temperature (50% RH) + slewing range (5% RH), the relay will switch on and start the output load; when the environment humidity is setting temperature (50% RH) + slewing range (5%RH), the relay will switch off and stop the output load.
Humidification control: When the temperature control mode (code is HC) was C, e. g. the setting control humidity is 50%RH. slewing range of temperature is 5%RH, when the environment humidity setting temperature (50%RH)-slewing range (5%RH). the relay will switch on and start the output load; when the environment humidity is set temperature (50% RH), the relay will switch off and stop the output load.
