KEYNICE USB Powered Digital Thermometer with Color LCD 🌡️ Display - Highly Accurate Readings in Fahrenheit and Celsius - Black Review

According to the description it can be used in cars. Does not work when the engine is running. My car is a Nissan Xterra. UPDATE: The company was kind enough to send me a replacement. This replacement worked at grade C, but after I removed the jumper on the back to change it to grade F, it didn't work with the car's engine running.

Cute little gadget! I use it as an aquarium thermometer and it's dead on temperature. Easily readable from across the room for a small display. And it's an impressive display that's easy to read straight away. Dear Keynice, Please start producing similar products for aquarists. For example a waterproof constant pH meter and alarms on thermometers like this one for high and low temperatures, all with the same type of display but with an extra long USB cable ;) I would buy them.

I got along a bit with this computer build since it was an old tower. I built in a simple fan controller with 4 fans and a single sensor temperature sensor. It has some gaming components, but nothing out of the ordinary. I like the blue display, but I've noticed that where I'm sitting the backlight looks gray and then light blue when I'm looking straight at it. It seems very accurate and I tested it with 2 other types I had, they were all within 1 degree. USB plug through the hole and plugged…

Bought to keep an eye on the water cooling tank for my laser cutter which it works great for. I was planning to power it with a standard lithium-ion power bank (like the kind you charge with phones, for example), but I ran into a rather interesting dilemma: the power consumption of this sensor is so low that all power supplies that I've tried turning off automatically (they are designed to stop current below a threshold to prevent parasitic current leakage), which turns off the sensor. My…

Despite all the suggestions that it is suitable for an aquarium, it has been working in my marine installation for two weeks now and works perfectly. It's very sensitive and responsive, and the temperature change flashes in a split second. One caveat: to get a Fahrenheit reading from the set degrees Celsius you need to remove a SMALL jumper wire inside. No operation, it is open and visible, but it slipped and fell into the device when I tried to remove it. I was concerned that this might cause…

So far so good, worked straight away, I put it in the door of my mini freezer that I carry under the cover in the back of my pickup when I tow my camper. Yesterday, July 3rd, it was 90 degrees Fahrenheit outside and I was getting warmer - 3 degrees Fahrenheit. Cold. So I turned off the freezer to save energy and not around the 8F. Still 24 below zero. Now I have popsicles, frozen drinks and frozen steak for any roadside emergency. The only problem is figuring out how to provide a continuous 5…

Brother this thing is as exciting as funky beats in house music. Bro, the colors on the display are really vibrant and mixed with live on-screen activity makes this little one eye-catching and bright. This is driving my nerd to the dog. For example I could only find flat analog strictly numeric displays, maybe the same color and only the numbers change, but not this little guy. This guy has a pressure gauge, a bar graph that changes with numbers, and a little thermostat graphic programmed into…

I live in the South West and bought this for my BMW R1100RT motorcycle which has no air conditioning so I wanted to measure the riding conditions for dehydration etc. for safety reasons when riding. I ordered a 4 pin version which includes a hygrometer (humidity) function, pulled out the Fahrenheit jumper on the back, cut off the PC connector, installed it in a US-SA-AJD-203842-Uxcell- box and connected the red-black wires to the 12V battery. This is exactly what Kenis described and exactly…

So far so good, worked first time, I put it in the door of my mini freezer which I keep in the bed of a pickup truck under the panel carry I am pulling my mobile home. . Yesterday, July 3rd, it was 90 degrees Fahrenheit outside and I was getting warmer - 3 degrees Fahrenheit. Cold. So I turned off the freezer to save energy and not around the 8F. Still 24 below zero. I now have popsicles, frozen drinks and frozen steak for any curbside emergency. The only problem is figuring out how to provide…

I installed this on my bike to know the ambient temperature. The display is easy to read in any light except when the sun is shining on it, so choose your mounting location accordingly. In addition, the sensor has a very fast response time. Therefore, it is important to find a suitable place for installation. Until I found the perfect place; When I stop, the temperature displayed slowly increases due to engine heat. As soon as I move and the ambient air flows through the sensor again, the…
