Review on 🏠 Enhance Your DIY Smart Home Projects with KOOKYE 16 in 1 Sensor Modules Kit for Arduino Raspberry Pi by Dante Obong

That's pretty good value for what you get. With that in mind, here are a few things to warn about: - Raspberry Pi manuals are missing. So if you're not already familiar with hooking up various things to the GPIO on the RPi, you'll need to do some research/learning. on your own to make them work. Hopefully you've done things like this before and don't have to hold hands too much. A number of sensors are analog with digital threshold output. This is a minor disadvantage if you have a Raspberry Pi without a built-in ADC (no analog inputs). You are either stuck defining thresholds, or you need to adjust the capacitor charge time or use an ADC. DHT11 is an older version of the temperature/humidity sensor. It uses its own crazy and slow serial protocol and I recommend downloading the Adafruit DHT Python library to read the sensor. The temperature on this one is pretty inaccurate but that doesn't matter as this kit comes with a much better temperature sensor (DH18B20). Humidity readings aren't overly accurate either, but humidity sensors aren't usually very accurate anyway. The DH18B20 temperature sensor is great, but remember two things: The pins on the small board are NOT in the same order as the pins on the bare board. Component. Ground is the middle pin and the 1-Wire output is marked S. The board has a small activity LED that lights up when you've connected it properly. Assuming you remember to enable 1-Wire in raspi-config, it will be recognized by the kernel and will work fine. The BMP180 barometric pressure sensor probably works great, but it comes with pins that are not soldered to the board. Plan on soldering them to yourself if you want to use this with a breadboard. You can expect some components like this to come with solderless pins. So if you've gotten this far without a soldering iron, you might want to get yourself one sooner rather than later. So overall it's a good value, but for RPi users without analog inputs it would be nice if it also came with an ADC, such as the B. the 4-channel 16-bit I2C ADC module ADS1115. This will likely increase the cost somewhat, although it's debatable whether they should include it in this kit as a result. KOOKYE's suggestions on how to improve this a bit: - Upgrade from DHT11 to DHT22 - Add an ADC, even a cheap one that's only 10 bits and 4 channels.
