Environment Click Board™

Product Code: MIKROE-2467

The Environment Click Board™ measures temperature, relative humidity, pressure and VOC (Volatile Organic compounds gases). The click carries the BME680 environmental sensor from Bosch. The Environment Click Board™ is designed to run on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface. You can use it to test your indoor air quality, to control HVAC (heating, ventilation, and air conditioning) systems, in a weather station, sports applications and more. BME680 Sensor Features The BME680 is as combined digital gas, humidity, pressure, and temperature sensor based on proven sensing principles. The humidity sensor provides an extremely fast response time for fast context awareness applications and high overall accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor with extremely high accuracy and resolution. The integrated temperature sensor has been optimized for lowest noise and highest resolution.

Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature. The gas sensor within the BME680 can detect a broad range of gases to measure indoor air quality for personal well being. Gases that can be detected by the BME680 include Volatile Organic Compounds (VOC) from paints (such as formaldehyde), lacquers, paint strippers, cleaning supplies, furnishings, office equipment, glues, adhesives, and alcohol. SPECIFICATIONS Type Environmental Applications Indoor air quality measurement, personalized weather station, home automation control, measuring ambient temperature, etc. On-board modules BME680 integrated environmental sensor Key Features A digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement Interface I2C,SPI Compatibility mikroBUS Click board size S (28.6 x 25.4 mm) Input Voltage 3.3V PINOUT DIAGRAM This table shows how the pinout on the Environment Click Board™ corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
