16 in 1 Smart Home Sensor Modules Kit for Arduino Raspberry Pi DIY Professional

Most of the coding you can do on a microntroller (Arduino, PiCo) for these can be semi-interchangeable. The only exception is the more challenging Temp / Humidity DHT11. But it was fun for that reason.I used most of these sensors with both Arduino and Raspberry Pi Pico and they worked out pretty well with both. There are some sensors such as motion, water level and gas detectors I have not tried, but the ones I did give me good confidence those will work.Since this is an assortment, this does not seem like the way to go if you want to set up a series of sensors somewhere (to guard a whole perimeter), but to get the knowledge of how these things work before that bigger investment, this could work rather well.

I decided to get the Kookeye sensor kit because their website had pretty detailed guides for each of them with instructions, code, and diagrams. I chose this set over those from other vendors because it included a wide variety of jumper wires that looked better than the set that came with my Arduino Starter Kit (this has been a plus).So far, I have tried out the following three sensors:1. PIR motion sensor. Worked after a little time delay adjustment.2. DS18B20 Temperature Sensor. There are incorrect hyperlinks on the Kookeye web site for this module. I used the search field on their web site to locate the correct guide.3. DHT11 Temperature & Humidity Sensor. The diagram of the module and wiring on the Kookeye web site are not correct for the 3-pin module in the kit. Read the markings on the sensor to hook it up correctly. Also, the link for the DHT library does not lead to a zip file.So there is a little frustration working with this kit, but it's been fun (I can say that now that the DHT11 is working). Just utilize the web to figure out the solution.------UPDATE:- I have now successfully used the Photosensitive Light Sensor Module, the BMP180 Barometric Sensor Module and the Relay Module. Easy to use although you have to search the web for the instructions because the Kookeye web site has several bad links.- The Water Level Sensor Module sort of works but is hard to decipher and calibrate for depth.- The only module that is a problem is the DHT11 with which I can get correct humidity readings but not temperature readings.AUTHCODE: CO022520KSK-UPDATE031220

This is a pretty good starter kit for learning how to put electronics together, and for programming basic commands tocontrol a machine.Everything worked great right out of the box with basic instructions on the website，althoght it's just a simple projects.but I'm really enjoying figuring out what I can do with it.

After contacting the seller, they happily fixed a shipping mishap that resulted in me missing some wires that prevented me from using their product. Now that I've actually had a chance to try their product, it works pretty well. My first project was to help my girlfriend track the temperature of an open air fridge to see how much it fluctuates throughout the day. The code and setup instructions on their websites was very clear (even for a person who doesn't know python). And within a day I was able to setup a raspberry pi to verify that the fridge was fluctuating by over 20degrees F. The module also measures in C. Look forward to setting up other fun projects with all the other sensors.

Yes , there are many other sensor collections; but to be honest, those collections can contain items that are a bit superfluous. I selected this particular collection for having only those sensors I am interested in. Your mileage may vary, and there are many other collections to choose from. I found this one to have the most interesting sensors to experiment with. Recommend.

Some of these sensors are rubbish - the DHT-11 in particular is terrible. When the actual temperature got below freezing, the DHT-11 started returning positive numbers. All the makers did was trim off the sign bit. Ickk. Useless. I could never get the HC-SR501 infrared motion sensor to work at all. I think it's just wrong. Might be missing a jumper.It does include a BMP180 and a DS18B20 which are good and work as they should.
