joy-it SEN-BME680 Temperature Air Pressure Humidity

Introduction

SEN-BME680

Temperature, air pressure, humidity and air quality sensor

GENERAL INFORMATION

Dear customer,

thank you very much for choosing our product.

In the following, we will introduce you to what to observe while starting up and using this product. Should you encounter any unexpected problems during use, please do not hesitate to contact us.

The BME680 from Bosch Sensortec is the new, compact environmental sensor with integrated sensor technology for humidity, pressure, temperature and air quality. The digital interfaces I2C and SPI also enable easy and fast readout of the measured values.

I2C ADDRESS CHANGE OF THE SENSOR

For this sensor the I2C address is 0x77 by default but can be changed to 0x76 if the SD0 pin of the sensor is connected to GND.

I2C address: 0x77

I2C address: 0x76

CONNECTION TO THE RASPBERRY PI

These instructions were written under Raspberry Pi OS Bookworm for the Raspberry Pi 4 and 5. It has not been checked with newer operating systems or hardware.

Setting up the Raspberry Pi

Before you can start using the sensor, you must first run the required commands to update your Raspberry Pi. These commands will update  your Raspberry Pi and make you download pip3, which will be needed later on.

Please run the commands below.

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install python3-pip

After you have executed these commands, you only need to enable I2C.
To do this, execute the following command:

sudo raspi-config

Now enable the I2C Interface at 3 Interface Options → I4 I2C.

Now create the necessary virtual environment for the project with the following commands:

mkdir your_project && cd your_project

python -m venv –system-site-packages env

source env/bin/activate

Use on the Raspberry Pi

After you have set up your Raspberry Pi, you can now download the library. We use the Adafruit_CircuitPython_BME680 library from Adafruit,
which is released under the MIT license, to drive the BME680. To install the library, run the following command:

pip3 install adafruit-circuitpython-bme680

Now, after installing the library, create a new file

nano bme680.py

You can then copy the following code sample into this file or you can alternatively download the code example here.

import time
import board
import adafruit_bme680

Creating a sensor object that communicates via the board’s standard I2C bus

I2C = board.I2C() # uses board. SCL and board. SDA
bme680 = adafruit_bme680.Adafruit_BME680_I2C(I2C, debug=False)

Change the value so that it corresponds to the air pressure (hPa) at sea

level.
bme680.sea_level_pressure = 1013.25

Normally you need to add an offset to account for the temperature of the

sensor.

This value is usually about 5 degrees, but varies depending on use.

Use a separate temperature sensor to calibrate this sensor.

temperature_offset = -5
while True:
print (“\nTemperature: %0.1f C” % (bme680.temperature + temperature_offset))
print (“Gas: %d ohm” % bme680.gas)
print (“Humidity: %0.1f %%” % bme680.relative_humidity)
print (“Pressure: %0.3f hPa” % bme680.pressure)
print (“Altitude = %0.2f meter” % bme680.altitude) time.sleep(1)

After you have copied the code sample, you can save the file with CTRL+O and then close it with CTRL+X.

After that you can try out the code sample directly and start it with

python3 bme680.py

You can then close the code sample again with CTRL+C.

CONNECTION TO THE ARDUINO

Installation of the Library

We use the library Adafruit_BME680 from Adafruit, which is released under the BSD License. You can install the library in the Arduino IDE under Tools → Manage Libraries… by searching for bme680 and then selecting the library from Adafruit to install.

Use on the Arduino

You can execute sample codes under File → Examples → Adafruit BME680 Library. With the code example bme680test you can easily test your sensor. Make sure that you have selected the correct board and port under Tools. Alternatively, you can download the code example here.

ADDITIONAL INFORMATION

Our information and take-back obligations according to the Electrical and Electronic Equipment Act (ElektroG)

Symbol on electrical and electronic equipment:

This crossed-out dustbin means that electrical and electronic appliances do not belong in the household waste. You must return the old appliances to a collection point.

Before handing over waste batteries and accumulators that are not enclosed by waste equipment must be separated from it.

Return options:

As an end user, you can return your old device (which essentially fulfills the same function as the new device purchased from us) free of charge for disposal when you purchase a new device.

Small appliances with no external dimensions greater than 25 cm can be disposed of in normal household quantities independently of the purchase of a new appliance.
