BME280 3.3V Atmospheric Pressure Sensor GY-BME280-3.3 Temperature Humidity Sensor Module for Arduino

This seems to be a good working sensor. I needed one for a project. The real one will be manufactured with the BME on the board. But I need to test to see if there are any conflicts wiring all the parts together. Modules like this are perfect for that. I don't have to build the whole thing, I can just plug in this module, that already has whatever resistors, capacitors, and diodes are required.The labeling is troublesome. It requires a bit too much deductive reasoning for SPI mode. Here's what the labels are. The left column is the BME280 label. The right is what it should go to.VCC = 3.3vGND = GNDSCL = CLK/SCKSDA = MOSI/SDI/DINCSB = CSSDO = MISO/SDO/DOUTIn the screenshot, I have it running in the Arduino IDE with Adafruit Library's example "BME280test". I'm using SPI mode, because my project requires it.I soldered the header on upside down, so the labels would be up. I figured this would be a pain, so I didn't want to have to flip it while figuring out the pin assignments. Normally, you'd want the chip with as much exposure to the environment as possible. It would have been nice if they had just labeled the top side, but what's done is done.Once you get it wired right, it works perfectly with the example code.I don't have long-term experience with this module yet, but it will be running constantly while developing the rest of the project. If it dies prematurely, I'll come back and lower the score.

対応、配送、梱包とても良かったです。

This is a no brainer. Couple this with an ESP32, and you have everything you need to monitor the environment inside a covered RV over the winter.Since I upgraded to a larger trailer this summer, I was no longer able to winter it in my shop (too tall). So I did what most people do and put a cover over it, but was concerned about the temp/humidity inside over the long winter. Now I have continuous readings of temp/humidity/dew point, so my home automation server will fire up the small heater when conditions warrant.Cheaper than building a new shop!!

I am using this sensor with my Elegoo Uno R3 in the Arduino Create Web IDE.I2C interface worked immediately with the adafruit universal sensor + BME280 drivers.Have tested side by side with DHT11 sensor and the discrepancy is within the listed tolerances of both sensors. I recommend calibrating if high accuracy is needed.Have tested at around 100 hz and getting reasonable results.I have struggled to get the SPI interface working, but this is possibly operator error. Took me awhile to find the SPI pinout diagram as the pin labels on the product are for I2C.Would/will purchase again.

When I first received these, I tried to run the simple example that comes with the Arduino IDE after installing the Adafruit library. It didn't work, said no sensor found. After a bit of research, I discovered that the library is set to 0x77 and the sensor is set to 0x76. In order for the code to find the sensor you can either modify the library (bad idea) or simply change your "begin" statement to look like "bme.begin(0x76);". That's it.The sensors now work fine.
