INTRODUCTION
The QK-W017 is a temperature and humidity monitoring WiFi gateway which communicates
either directly with your phone or tablet or through an access point (router) to control and
oversee up to five independently adjustable environment zones. The main gateway unit works
with wirelessly connected terminals to form a versatile device which can be installed with
appliances such as domestic freezers, water tanks, refrigerators, industrial chillers, boilers,
steamers, warehouse controls, greenhouses, industrial equipment and other systems requiring
temperature and humidity control. Operators can check and adjust environmental conditions
and control remote equipment, heaters, lights, or machines from anywhere in the world via the
Internet, and check conditions in real-time at the click of an icon.
Up to five RF sensor terminals measure temperatures and humidity in different zones and QK-
W017 operates the corresponding relays according to the measured temperatures and/or
operator commands. QK-W017 can be fitted in any situation where an object or area needs to
be heated, cooled, or both in order to maintain the target temperature range (set within the
Android/iOS APP).
An integrated WiFi module allows the operator to check the temperature log data and manually
switch the relays via a WiFi network or on site.
