Hot selling MCU-680 BME680 Temperature, Humidity, and Pressure Sensor Ultra small Pressure Height Development Board

Product Introduction

The BME680 environmental sensor is a four in one MEMS environmental sensor that can measure four parameters: VOC (volatile organic compounds), temperature, humidity, and air pressure, making it very suitable for monitoring air quality. Due to the use of MEMS technology, this sensor has a small size and low power consumption, making it suitable for low-power applications such as wearables.

The DFRobot Gravity BME680 environmental sensor adopts the Gravity I2C interface, which is plug and play and easy to connect; Onboard power regulator chip and level signal conversion chip, with good compatibility, can directly support 3.3V and 5V systems; Reserved SPI interface for easy expansion. This product has high integration and can simultaneously detect four environmental parameters, making it an ideal choice for scenarios such as weather stations, smart homes, the Internet of Things, and wearables.

By using this product, you can quickly set up an air quality detector. With the increasing severity of air pollution and the frequent occurrence of furniture with toxic substances exceeding the standard, it is time to take care of your health.
