“A nicely-made breakour for a common sensor. I like the fact that it does NOT have an LED onboard (like the similar Adafruit part) as that consumes power and doesn't play well with the sensor's deep sleep capability. The first ones I bought didn't have the QT/ST connector, which some will find useful.”
“Works great. I enabled I2Con the Pi, plugged the BME280 into the breakout garden I purchased at the same time, installed the necessary pyton library using the provided script, and opened one of the example python scripts provided. Bingo; I now have a humidity and pressure sensor running in my kitchen, and as it's on my wifi, I can vnc in from my phone at any time to check the readings. I did initially have the temperature sensor running too, but as it's so close to the pi, which is running at 40+ c, the readout is skewed, so I turned it off. But that's not aproblem with the sensor hardware.”
“I have several of these, which I use with Arduno IoT to monitor conditions remotely. They are easy to set up and use, reliable and agree to within about 0.5 C when exposed to the same conditions.”
