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

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!!

Used this in a Meshtastic node, and the module was easy to use. No setup or software needed, simply wired it to the project board and it started working right away.

decent BME280 sensor though first one was DOA

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 = 3.3v GND = GND SCL = CLK/SCK SDA = MOSI/SDI/DIN CSB = CS SDO = MISO/SDO/DOUT In 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.

Tried connecting this bme280 to a esp32 and could not read any measurements from the chip. I then tried to search for i2c addresses and could not find any devices.

The boards worked well. I used four pins: the I2C and power/ground. I connected it to an Ideaspark LCD board and set up a display to test it. The humidity seemed to be high right after I soldered the pins but that settled down the next day. It was easy to use and a great way to get started with the Ideaspark Arduino board.

This sensor can detect up to 0.01C resolution temperature difference from a puff of wind. Bosch Sensortec BME280 sensor driver is available on Github and it provides temperature, atmospheric pressure and humidity output, quick and easy. As other review pointed out, this device should use 3.3v for VCC according to Bosch Sensortec BME280 spec.

I've used several different flavors of this module in weather station type applications, and they all perform well if placed correctly in well aspirated stevenson shield (if outside). Inside, just get keep them away from the ESP or Arduino device so that the microprocessor's heat doesn't influence the readings. There are tons of libraries out there for interfacing with it over I2C and SPI. If accuracy is a priority, don't waste your time with the DHTxx series of sensors. They're fine for approximating temperature, but with this module you get incredibly accurate temperature and humidity and pressure to boot.

対応、配送、梱包とても良かったです。
