The QK-W016 series WiFi temperature monitoring remote controller is a versatile device which can be attached to appliances such as domestic freezers, water tanks, refrigerators, industrial chillers, boilers, steamers, warehouse controls, greenhouses, industrial equipment and other systems requiring temperature control. Operators can control remote equipment, heaters, lights, machines or power sockets from anywhere in the World via the Internet.

Three wired thermistor sensors measure temperatures in different zones and QK-W016 triggers the corresponding relays according to the measured temperatures. The QK-W016 can be fitted in any situation where monitoring and regulation is necessary in order to maintain the target temperature range (set with the PC application or the Android APP).

An integrated WiFi module allows the operator to check the temperature log data and manually operate the relays via a WiFi network.

QK-W016 also has an optional RF433 Mhz module which allows the operator to operate RF mains sockets within a range of up to 50 metres.  Please contact us to include this module in your unit.

The PC application does not support far-end control through the Internet. This means QK-W016 should be connected with the control computer through the same Access Point (same SSID name) as the controller. To control QK-W016 from any location, operators should use an Android based terminal, like a mobile phone or tablet, to access the controller over the Internet. The setup process is similar to the Windows application. The main control panel on the Android APP is illustrated below.
