Review on 🌡️ KOOBOOK 5Pcs GY-BMP280-3.3 High Precision Digital Barometric Pressure Altitude Sensor Module for Atmospheric Pressure Sensing by Michael Welborn

I tried several example programs for Arduino and none of them worked. I found that the received I2C address is 0x76. I made modifications to the Adafruit example and all five worked: if (!bmp.begin(0x76)) { // Omit 0x76 for standard I2C address 0x77. I ran all 5 and looked at the range of readings. They fell into 3 clusters; usually the difference between the extreme values is more than 280 Pa, which should not be the case with an absolute accuracy of 100 Pa, as stated in the data sheet. A difference of 200 Pa might be acceptable. It is possible that these devices are defective. "Noise" is assumed to be 1.3 Pa at full bandwidth; I have a standard deviation of 0.8 Pa to 3.7 Pa. The configuration was the same for each part, but I'm not sure if it was optimal. humidity sensor. I've had several BME280s, including one from Sparkfun, and they've all failed in one way or another, so these inexpensive, pretty good barometers might be for me. I hope.
