Описание
Module with sensor BME680 from Bosch, it includes measurement of temperature, humidity, pressure and gases. It is able to measure humidity from 10% to 90% RH, pressure from 300 hPa to 1100 hPa, temperature from -40°C to 85°C and the gas from 0 IAQ to 500 IAQ. It communicates via I2C or SPI. Details of measurement are available in the documentation.
Sensor BME680 includes a small sensor MOX. Heated metal oxide changes the resistance basing on the volatile organic compounds (VOC) contained in the air, allowing it to detect gases and alcohols such as ethanol, alcohol and carbon monoxide. It can also be used for measuring the air purity.
This sensor, like all sensors of VOC / gases, is unstable. For accurate measurements, you must calibrate it with the known sources.
PinsThe module is powered with the voltage from 3.3 to 5 V, it communicates via interface SPI or I2C. It is compatible with Raspberry Pi and Arduino. STEMMA QT / Qwiic connectors can also be used to connect the sensor with the main module. Detailed information is available in the user manual provided by the manufacturer.
PinDescription
Vin The module's supply voltage ranges from 3 V to 5 V. GND The ground of the system. 3Vo Regulator's output of 3.3 V with the current of 100 mA. SCL Clock line of the I2C (TWI) / SPI bus SCK Clock line of the I2C (TWI) / CFI (MOSI) bus SDOOutput line of the data (SDO / MISO)
CSSelection of I2C / SPI. Pin is not connected or connected to a high status, it selects the I2C communication, it is connected to low status and selects the SPI communication.
SDIInput line of the data (SDI / MOSI).
CCSClock line of the I2C bus.
SDIThe data line of the I2C bus.
The product is compatible with Arduino
