It’s easy to remember when wiring them. The 2nd soil moisture sensor will allow me to monitor both plants at the same time. I connected pin 5 (SDO) on the AE-BME280 to GND but you can also connect it to VDD. The portion of code that I customized is as follows: I didn’t modify the codes too much. [Others] Grove Shield - Barometer Sensor (BME280) After you’ve successfully connected BME280 to your Raspberry Pi, it should be like below image. It’s useful to have a desoldering wick ready in case you mess up. It's easy to use the BME280 sensor with Python or CircuitPython and the Adafruit CircuitPython BME280 module. It is now complete! I wasn’t able to open the file but I’m assuming it contains the recorded measurements. I have a Raspberry Pi 3B+ and I bought two BME280 sensors (specifically these) and I would like to connect them via I2C.I read that you can do software multiplexing but all the information I am finding is incomplete, makes assumptions, or people are commenting that it doesn't work. Developed and maintained by the Python community, for the Python community. to use, copy, modify, merge, publish, distribute, sublicense, and/or sell Further technical details for the BME280 sensor can be found in the datasheet [PDF]. So, I recommend unplugging the soldering iron from the power outlet and cool it down before applying again. It's Raspberry Pi and Arduino-compatible. J3 is close to its neighboring pins so be careful not to connect them. which has the same chip. It has been running without issues for over 12 months. It's Raspberry Pi and Arduino-compatible. The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time.
