G1Tech BME680 – Temperature, Humidity, Pressure and Gas Sensor

Brand-new instrument for the measurement market, a small sensor that can measure: Temperature, Humidity, Pressure and VOC. Bocsh made VOC measurement new in the sixth series

Sensor parameters and its form factor were also slightly changed.

Package: 3.0 mm x 3.0 mm x 0.93 mm metal lid LGA
IAQ range: 0-500
Humidity range: 0-100%
Pressure range: 300-1100 hPa
Temperature range: -40-85°C

Is there any point in using this sensor in your DIY?

Let us look straight to the CONS of this sensor:

  1. Current consumption when measuring VOC is 18mA, which is a lot for low-power devices
  2. The sensor must work for at least 30 minutes to normalize VOC measurement
  3. Complex logic in converting resistance to VOC, however this can be solved using the API sensor.

Thus, if you do not create a low-power device, you get a compact sensor that can measure 4 parameters.

To test this sensor, we created a prototype module, according to the datasheet and after a month of testing, we can conclude: You can use bme680 when you are limited in space, in other cases we recommend using bme280 in conjunction with CCS811.
