DIY Soldering Practice Kits DS18B20 Temperature Sensor Module DIY Electronic Kits Soldering Project Kit 0-99 ℃ (32℉-210℉) Dingdong Store

I bought four of these for a learn-to-solder class and today I assembled one of the kits. After assembly it worked, first try! I give this maximum rating, like if there were 10 stars instead of five it would be all 10 stars and the reasons for this are about how the kit and instructions (it included instructions!!! In English!!!!) are arranged. All of the similar parts like resistors are grouped together, so all of the resistors of the same value are on the same tape. Same thing with the transistors, they are all TO-92 packaging, but the temperature sensor itself is kept separate. All component locations are clearly marked on the printed circuit board and polarities are marked when appropriate. They got it right. Everything, from the orderly instructions with pictures, component placement is logical and not too close together, the silk screening is accurate and clear, I do not know what else they could have done to make this an overwhelmingly positive experience!

This was a straightforward and enjoyable build, perfect for a quick soldering session without any surprises. The board layout is clean, the pads take solder well, and the component count is low enough that even a beginner can move through it confidently. Everything fit as it should, and the finished module worked immediately once powered up. It’s a satisfying little project for sharpening technique or warming up before tackling something more complex. A solid pick for easy practice and a reliable result.

This kit works fine. It has two alarms: one for over temp. and one for under temp. These are easy to set. Bright display. As usual, the English instructions are some what humorous, but easy to figure out what they mean. The kit came with a few extra parts, but better that than too few. Display is in degrees Celsius. Works with a 5 volt USB connection and comes with a cable. I like it. Only disappointment is that the links to additional information don't work. I'd like to know how to use the four terminals labeled +, -, R, T.

Went together fairly easily and works well. Definitely a fun kit for a beginner. As with most of these beginner kits, the best idea is to scan the QR code on the included instructions to access the full build document on their website. Use the full set of instructions on the website's PDF document rather than the bare-bones instructions included with the kit. My only two minor beefs are that 1) you are locked into Celsius. I could not find a way to toggle between Celsius and Fahrenheit. and 2) the unit does not measure below freezing (0 C or 32 F) although that limit is clearly stated in the product description.

The PCB is single-sided but with plated through-holes and pads on the top of the board. This is the second time purchasing this item. One will be left mostly "stock", the second will be used as a test bed to add functions. First is adding a Fahrenheit option to the display, as this is only a code change. Next is swapping out the .364" display for a .56" display. Later, adding a battery-backed up RTC and adding a clock function, in addition to the temperature display. Maybe also adding a light sensor for auto-dimming of the display.

I received this package fine everything seemed to be in the package. However when I went to solder in the power connector I noticed it was in the package. Thinking I would deal with that later I continued. after soldering more parts I got to the section where the instructions say to solder in the ic socket. The socket had one pin totally missing and another pin just sitting on top of the socket. the socket itself is not damaged so its not a shipping issue but someone just put a defective socket into the bag. Really what do you want for $8? ive bought lots of these cheap Chinese kits and never had an issue. I don't know if this works or not because with a broken socket I can't use that. I guess I can just solder the chip in. Don't buy from this company they send out defective items.

Some report poor temperature performance, i have 5 other devices showing the same temperature to the tenth of a degree. I have not tried, but have seen information about using a computer over another usb port to actually program the device. If you check the temp right after turning on, it will be off by as much as 3 degrees C but after 30 minutes on, it is correct.

The advertisement says "Included Components: Soldering Station Body, Soldering Iron, Iron Holder, Tip Cleaner, Solder Sucker, User Manual, Helping Hands, Light" but none of these items are included, only the components which don't actually match the bill of materials as to quantity. I had a number of extra parts. The assembly instructions are random with little thought to the assembly proces. The product does work but totally misses the possiblities of actually learning something from the kit. They have a microprocessor so to add functionality like an °C/°F selection would cost nothing except some code added. There's so much potential here that's not met. There is not even a schematic of the circuit so all you get is practice in soldering with no guidance in that.
