the model received is not exactly of the image, but it's a true BME280 and works perfectly. the breadboard contains a pull-up resistors, necessary for I2C and SPI protocols. I have worked directly on arduino, but for security, you use a level-shifter for adapt the logic levels (5v-to-3.3v). pd. I see multiple comments that say that module is not a BME280, is a BMP280. The marks on the module can induce an error, but the chip is a REAL BME280 and reads good the temperature, pressure and humidity.
I just hooked this up to an ESP8266 NodeMCU board using the Arduino IDE and firmware and it works great with the Adafruit BME280 library. Like others have said, I just had to change the I2C address to 0x76. The temp and humidity values seem comparable to the readings I was getting from the DHT22 sensor that I replaced with this because I also wanted barometric pressure readings. Wish these would be a bit cheaper but I only need one of them, the rest of my boards will be fine with DHT22s for temperature and humidity. I'll be running this enclosed but outdoors year-round so I'll report back if I find any issues with it under temperature extremes (at least as extreme as they can get in the Chicago area).
this is NOT the BME280, I got BMP280 with no humidity reported by the sensor. The marking on the chip shows it, too, as I know for now. I trusted the reviews, but obviously they changed the board. You can look it up in the data sheets: BME280: https://www.embeddedadventures.com/datasheets/BME280.pdf (chapter 7.7) BMP280: https://cdn-shop.adafruit.com/datasheets/BST-BMP280-DS001-11.pdf (chapter 7.3) The BME280 with humidity measurement has one dot and one vent hole, the BMP280 only has one dot - which fits to the product images, but not to the description which says this is the BME280.
Got it working, with a ES8266 ESP-12F (Geekcreit) and I2C, but not without a effort. Found this thread, which helpt me : http://embedded-lab.com/blog/making-simple-weather-web-server-using-esp8266-bme280/
Can work I2C or SPI. In the picture work SPI. Nice accuracy and resolution data :) Recommend. Descriptions of parameters shown in the attached image in Polish ;)
I wan my money back!! It is not a BME280 (Humidity,barometric and temp sensor). It is a BMP280 (barometric and temp sensor). Bad description!!!
Good quality. Works well
Good price an quality.
Good quality product
Ok
