RS Components (RS) markets Bosch Sensortec's BME680 four-in-one sensor for measuring environmental parameters, together with the associated evaluation board that simplifies product development. This sensor, which combines temperature, humidity, pressure and gas measurement capabilities, is aimed at low-power applications with high cost and space constraints.
The BME680 sensor, integrated in a package measuring just 3 mm x 3 mm x 0.93 mm, minimizes average power consumption by combining an energy-saving active mode, known as forced mode, with a low-power standby mode consuming just 0.15 µA. In forced mode, the sensor sequentially cycles through temperature, pressure, humidity and gas measurements before automatically reverting to standby mode.
Fast sensor response minimizes cycle time in forced mode. Measurements can be switched on or off individually to reduce energy consumption. To optimize energy consumption, up to ten temperature and time settings can be stored for the internal heating of the gas sensor.
The BME680's excellent accuracy and linearity make it ideal for air quality measurement applications, or for use in weather monitoring stations. The sensor is also ideal for context detection in wearables and home automation devices, personal navigation systems, sports trackers and advanced industrial displays. Its 8-pin LGA metal housing provides high stability and immunity to interference, enabling it to be used in harsh outdoor or industrial environments.
RS also offers the BME680 evaluation board, which contains a ready-to-use BME680 sensor with all pins accessible to facilitate application development and testing. This board, which uses the same standard footprint as Bosch's evaluation boards, can be used directly within customer projects, or in conjunction with Bosch Sensortec's application board and configuration software to adjust sensor parameters and values to be monitored.
Users of the BME680 can also take advantage of rich development resources, such as Bosch's environmental software cluster, to manage sensor data and perform calculations to assess air quality by combining the values measured by the sensor.
