BME280 Digital 5V Temperature Humidity Sensor,Atmospheric Barometric Pressure Board with IIC I2C Breakout for Arduino(4 Pack)

I ordered one package of this. One didn't seem to work, but the seller gave me a replacement immediately after I left feedback. The replacement was shipped immediately and it worked. I then ordered six more packages from this seller. Excellent product and excellent service for a very good price!

Easy to setup. However I need to improve my solder skills ;-), the board is tiny and it was a bit challenging to solder the connector. It's better to use right angled connector, than the straight one provided, if you have some around.The sensor is accurate and libraries are widely available for both Arduino, rPi and micro-python boards.

Surprisingly accurate. I compared three and were within 0.5C Temp, 0.5hPa Pressure, 1.5% humidity

Used one and it just so happens I opened the only one which had a sensor on board. A few months later when I went to use another one, it took me a little while to figure out it wasn't work because there was no sensor on the board! I checked the remaining 2 and neither had sensors as well. Too late to return now.

No complaints. Using this in an HVAC system to monitor everything inside and out with 2 sensors. Works perfectly fine with a Wemos D1. Great part is that there's a solder point to switch the address between 77 and 76. Means you can run 2 of these with a simple solder joint on I2C instead of complex code or multiplexers. I will likely buy more of these for other projects.

Ordered and quickly received from US stock four BME280 sensors. Three of the four seemed to be spec compliant and one had a bad humidity sensor. Vendor responded quickly, asked if I wanted a refund or a replacement part. I elected to have them mail the part (they warned that it might take 30 days, but it took 17 days and the new part seems to be a good part so kudos for standing behind the warrenty. Very satisfied. Would buy again.

This product is hardwired to device address 0x76. I was using the Adafruit_BME280_library which defaults to device address 0x77 hence the example test programs reported device failure. To fix the Adafruit test programs and/or other programs using the Adafruit_BME280_library to use this type of bme280 module, modify the bme device initialization call from: bme.begin();to bme.begin(0x76);Had I known this before I returned this order, it might have saved everyone the inconvenience of returning this order.My apologies to all.

Of the 4 I received, only two worked (1 never worked, wasn't recognized, the other one would work for 10 minutes and then transmit bogus data).Add to that that they are in fact expensive (especially considering you have to solder on the headers yourself): I mean, those simple sensors are more expensive than a genuine entire ESP32 development board with headers soldered on (complete with dual core cpu, tons of IO, and WiFi and Bluetooth connectivity)!So, yeah, not too happy.As for its design, if you want to change the I2C address, you have to cut a trace and make another solder joint. That could have designed much better! (I can live with a single solder joint, but as for cutting that trace, on such a tiny board, that's easier said than done, especially when you're as blind as I am! ;-) ).
