WiCub 2 FAQs

Is the battery replaceable?

No – WiCub 2 uses a rechargable battery that lasts 40+ days. Charge it using the USB micro port on the side.

Can I see a sample report?

WiCub 2 Daily Report

How many email alerts can I get in a day?

WiCub 2 sends out a maximum of 10 email alerts per day. This could be a mixture of IAQ, temperature, humidity and pressure values that are out of their set bands.

The temperature seems much higher when charging.

Yes that is expected as the internal battery, like all rechargable batteries, warms up during charge. A temperature compensation algorithm is in place during the recharge cycle that affects the accuracy of the sensor. The temperature normalises within an hour from when the charge is complete.

Can you customise WiCub 2 for me?

Yes we can – we have done custom firmware developments for some of our other clients. Please contact us for more information.

What sensor does WiCub 2 use?

WiCub 2 utilizes the Bosch BME680 sensor, a MEMS micro-hotplate MOX (metal-oxide) gas sensor.

How do you calibrate the sensor?

Calibration is performed automatically in the background if the sensor is exposed to both clean and polluted air for approximately 30 minutes each.

What gases does WiCub 2 measure ?
The sensor value increases or decreases based on the reaction of the gas-sensitive layer to oxidizable or reducible gases in the air. Thus WiCub 2 is sensitive to nearly all VOCs but remains a tVOC sensor (i.e. is not selective to specific compounds).
What approvals does the sensor have?

As the sensor is primarily used for CE applications and not for use in safety applications, it has been qualified against JEDEC qualification test methods and ISO16000-29 Profile.
