VABIRA VBR Sun UVI Index Meter حتى 22 مع إنذار الأذى بالأشعة فوق البنفسجية ، حماية حروق الشمس مع تذكير صوتي بالصفير

I got this for beach days and other outdoor activities, as a tool to remind me to re-apply sunscreen or tap out from the great outdoors for a bit. For my purpose an overall reading is good, no need for detailed information, and for this, it works as intended. At this point, I have no other more sophisticated tools or meters to use as reference point so I have to trust its readings. I find that the readings depend on the direction the lens is facing. I keep it aimed directly into the sky (lens direction perpendicular to the ground) regardless of where the sun may be in relation to the horizon. I like that it is about the size of a portable power bank and weighs about 3.5 ounces so it’s fairly portable.

Current price point at the time/date of this review: $60 with no discount/coupon being offered. Pricing is fair all things considered. The UVI meter appears to accurately detect UV radiation and will notify you when it’s necessary to take cover.A nice wireless tool to have handy which easily pairs with your phone for those long sunny summer beach days where you lose track. Also would work great on days where it’s a little more uncertain what the UV index would be for a particular time/season and where you don’t want to overextend your exposure.Works great as a reminder for when to bring the kids in under the umbrella. Trying to keep a sun burn free summer this year and this tool will be a definite aid.

El cacharrito es sencillo pero hace cosas interesantes. El sensor requiere una app que hace las veces de pantalla del aparato. El QR para descargarla está en el manual. Una vez conectado se orienta al sol o hacia donde debe estar si esta nublado y muestra en tiempo real la cantidad de radiación ultravioleta que se recibe del sol. Esto ya sirve para comprobar el filtro UV de las gafas de sol aunque no es su función principal. Le pones gafas delante y miras la pantalla.Sirve para no quemarse. Lo dejas al lado de la tumbona y cuando hayas recibido suficiente dosis de radiación ultravioleta hace saltar la alarma. Antes habrá que configurarle en la app el tipo de piel que viene con tres opciones: “Intolerance” que debe ser piel blanca de invierno, “common” y “tolerance”.Sólo funciona con el sol. En interiores no sirve para nada.No especifica si tiene alguna resistencia al agua aunque el manual dice que no se apaga ni aunque llueva. Viene con dos pilas pero sólo necesita una. El manual está sólo en inglés. Es sencillo y está bien hecho pero para quien lo entienda.Dejaré un foto y una captura de la pantalla del teléfono.

I got this UV sun protection warning system to keep track of how damaging the sun's rays are in terms of getting a sunburn. It is similar to the photo flux meter I got a while ago. They look the same except this is white the other is black; both are from the same manufacturer and have similar circuitry to measure different parts of the electromagnetic spectrum. The other one designed to help with indoor plant growth, this one designed to monitor your sunburn danger. I appreciate that it has a replaceable battery, which can of course be rechargeable if you choose, because if it had a built-in non-replaceable battery then when that goes bad after several years you have to toss the whole device, losing the value of your investment, unless you want to take the device apart and solder in place a new battery pack; a lot of easily avoidable work. Also with a built-in rechargeable battery when it needs to be recharged, wherever you are using it, you have to stop using it and wait till it recharges a-couple hours; you did bring a recharger with you, didn't you?. If you use rechargeable loose batteries you can carry extras with you and just pop one in when the previous one gets low.The Vsensor app you need to download and use on your smart phone to connect to the device is very friendly and doesn't ask for any strange or invasive permissions. The fact that you need to use Bluetooth for connection and if you plan to use this to monitor sunlight for several hours, you'll need to be sure your phone is fully charged before hand and also be sure to recharge it afterwards. My experience is that Bluetooth usage drains my battery more quickly. In conclusion highly recommend if you need information about protecting yourself and/or your children/the elderly from painful, skin damaging sunburn since many people think they can't get sunburned if it's cloudy.

I was a little dubious when I pulled this out of the package, wondering if it just sensed visible light, not UV, but I tested it, and it does, in fact work!It takes batteries, unfortunately, rather than being rechargeable, which is unfortunate, but with batteries in, and the app downloaded, it quickly started talking to my iPhone. To test it, I tried several very bright, and hot lights, and it registered zero. I took it outside, and in the shadow, it registered a 0.2. Walking out into the wan early March southern Ontario winter sunshine, it jumped to 1.2, so it clearly was reading something other than light intensity. I’m looking forward to seeing what it reads on a blisteringly hot and bright summer day.My only complaint is the interface - you set your skin type, from burns easily, regular, or burns slowly and warns you if it goes over the limit. I’d rather see a bar or waterfall display that shows where you are in the “going to get cooked” scale. Obviously, the 1.2 reading I got today probably means I can stay outside for hours without problems, but all I know is that the alarm didn’t go off. *RECOMMENDED*
