CJMCU-280E BME280 Hochpräziser Atmosphärendrucksensor für Arduino
Good product. Reads temperature, humidity, pressure and altitude. Tested the values with internet, and the values are a bit off, but all in all accurate enough. Note that this is a BME280 clone with SPI bus and won't work with I2C. Used some extra days on shipping, but I'm still overall pleased with my purchase.
Globalement bon produit, bonne fabrication, mais qualité moyenne, emballage antistatique
Good quality. Works well
Good price an quality.
Always a fantastic product
Fast delivery, proper packaging, testing in progress. Thanks
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
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 -
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 ;)
