UV 3 click – UVA light sensor
Posted by Lana Vulic on 10 August 2017 10:42 AM

It’s August, which means it’s time for a new UV click board™ – the third one to be precise. Maybe you don’t know this, but we’ve been releasing ultraviolet light sensor click boards™ during the month of August in the past three years. UV 3 click in no exception.

You can get the most use out of it during these hot days. The air is heavy with the smell of sunscreen, and everyone is worried if their skin is safe from the sun’s radiation. It’s so hot you could fry an egg on the sidewalk.

Well, our new click is there to tell you everything you want to know about the level of UV radiation.

UV 3 click

UV 3 click is an advanced ultraviolet (UV) light sensor with I2C protocol interface. The click carries VEML6070 UVA light sensor designed by the CMOS process. UV 3 click runs on either 3.3V or 5V power supply.

VEML6070 incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip. VEML6070’s adoption of Filtron™ UV technology provides the best spectral sensitivity to cover UV spectrum sensing.

For more information about the click, see the product page.

Yours sincerely,

MOTION click – detect human movement
Posted by Lana Vulic on 08 February 2017 04:10 PM

MOTION click will let you know whether someone has entered the room, or left it. If that someone has a physical body the click will detect it, so ghosts are excluded from the detection range.

How PIR sensors work

All objects emit radiation, and human bodies emit radiation of a certain wavelength. The hotter an object is, the more radiation it emits. The radiation emitted by a human is for the most part in the infrared wavelength.

A pyroelectric sensor, like the one on MOTION click, generates a voltage when exposed to infrared radiation, emitted by live bodies.

MOTION click range

MOTION click has the range of up to 4 m. So, if you place it in a room, you can use the onboard potentiometer to the range you desire. Once someone steps within the range the sensor will register thermal energy of their body, and send an interrupt to the target MCU.

You could know if your dog went into the kitchen when you are not there. Maybe you want the light in your front yard to turn on every time someone steps near it. You could set up a burglar alarm. Anything that incorporates detection of live bodies.

Other motion sensor click boards

Of course, we have other motion sensor click boards available. Here is a selection, and you can check the rest in our shop.

You can detect vibration with Vibra Sense click, the name itself says it all. Tilt click is a 4-directional optical tilt sensor that you can use to get positional feedback for left, right, backward or forward movement.

If you want accurate positioning and orientation information, look no further than 3D MOTION click.

For more information about the MOTION click, see the product page.

Yours Sincerely,

Test your indoor air quality with Pollution click
Posted by Lana Vulic on 20 January 2017 02:58 PM

Discover if the air quality of your home is good enough with our new Pollution click. It has high sensitivity to organic gases. This click is the 8th gas sensor click in your range, and you can check out the other seven here.

Pollution click

Pollution click carries the WSP2110 VOC gas sensor and runs on a 5V power supply. The sensor can detect gases such as benzene, methanal (also known as formaldehyde), toluene and more. The detection range of the sensor is 1~50ppm (part per million).

Whale oil and aftershave

In 1825 Michael Faraday discovered benzene, a natural hydrocarbon, and component of crude oil. Those days people created portable gas by dropping whale oil on hot furnaces. That oil gas was then condensed in a liquid form. Faraday discovered that it contained a substance which he called bicarburet of hydrogen and that we today call benzene.

We skip a few steps, and get to the 20th century, where people are using benzene in manufacturing everything from aftershave lotion to solvents for degreasing engines. Thankfully, today we know that benzene is a carcinogen, so it’s used only in some industrial processes.

With Pollution click, you can find out what percentage of benzene is present in the air. Or other organic gases.

For more information about Pollution click check out the product page.

Yours Sincerely,
