DIYmall Bme280 Pressure Temperature Arduino Review

Works great with no complaints. I can see the pressure, temperature and humidity around me. Many thanks to Matt, the author of the Python script listed at the "link" in the "Frequently Asked Questions" section. He did the hard work with Python programming. See the question "Will this work with Raspberry Pi?". Pros:* Works as promised.* Quality product. The BME280 libraries are available for both Python (see answer to "Will this work with Raspberry Pi?") and from Adafruit. Cons: * It would be…

Great packaging and quality from DIYmall as always. I used this and the MiniDK https://www.amazon.com/gp/product/B07BB8FLSY/ to build an indoor weather station. These sensors are very accurate! I have measured the barometric pressure which this sensor relays to the local weather station and the pressure is always right on the nose. Temperature and humidity are also accurate when compared to other devices I've placed in the same vicinity. If you need accurate local weather data for your…

I bought and continue to buy from DIYmall because of the careful packaging, product quality and their support. I've used them to build several weather stations and my friends keep asking me to build them too. I compare the barometric pressure accuracy to a military base only 2 miles away and it is always accurate. The temperature and humidity are also correct, as I have checked with other sources.

This little miracle will change my life. I feel the rush Nobel Quality Research: Probably not. But great data collection capabilities for only $13. So buy, taste and don't fry. and if you decide to try the Adafruit Support Library for Raspberry Pi, be sure to check the i2C address. By default, Adafruit assumes 0x77, but this device accesses address 0x76, connecting SDA to SDA and SCL to SCL.

I have yet to confirm the accuracy of this little device but observing it is close. I had it up and running in 10 minutes (not counting the time it took to solder the 4 pin connector). I used the Adafruit BME280 library and example. Just remember to change the I2C address from 0x77 to 0x76. Attached is a photo of BME280 along with 5x V3.0 USB Nano ATmega328P 5V 16M Arduino TE359 Microcontroller Board Module and Diymall® 0.96 inch Yellow and Blue I2c IIC Serial 128x64 Oled LCD Oled LED Module…

I really liked this sensor as it accurately shows altitude with a small margin of error which is normal for all electronic devices. I plan to use it for my drone along with a gyroscope and arduino. Make sure to use 0x76 when using the Sparkfun library to properly initialize the sensor.

Update #3: These sensors are incompatible, poor quality, unreliable and do not provide reliable readings. A bme280 replacement from the same manufacturer, DIYMALL, gives even worse (i.e. wrong) readings than the previously bad sensor! Example: 2016-09-24 08:59 83.1 30.1 65.7 <- first bad sensor relative humidity. Barometric readings appeared normal. *but* Attention, *current* wx conditions were: 81F with 87% !*avoid* the sensors of these manufacturers! they are bad, I repeat, bad. They fail…

I just connected this to the ESP8266 NodeMCU board with Arduino IDE and firmware and it works great with the Adafruit BME280 library. As others have said, all I had to do was change the I2C address to 0x76. The temperature and humidity readings seem to be comparable to the readings from the DHT22 sensor which I replaced with this one as I also needed the barometric pressure readings. I wish they were a little cheaper but I only need one of these, the rest of my boards will be fine with DHT22…
