D-FLIFE 2pcs BME680 Temperature Humidity Pressure and Gas Sensor Breakout Board Module 3~5VDC CJMCU-680 BME680 Sensor($26.99Value)

Description

The BME680 pressure sensor board is a 4-in-1sensor that can measure changes in Temperature, Humidity, Pressure and VOC Gas. It is very suitable for detecting air quality. The cjmcu-680 high altitude sensor module is sensitive, ultra-small pressure height development board. The cjmcu-680 sensor is simple and convenient to use without complicated procedure. Simply supply power and connect the digital communication pins (I2C or SPI) for your compatible with ESP8266 etc. The onboard power supply voltage regulator chip and level signal conversion chip have good compatibility and are directly compatible with 3.3V and 5V systems. Simply supply power and connect the digital communication pins (I2C or SPI) for your compatible for Arduino, ESP8266, Raspberry Pi, etc.

The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles.

The BME680 is a low-power sensor that detects with high linearity and accuracy temperature, humidity, barometric pressure, and VOC gas. It includes both SPI and I2C interfaces for reading the measured values using our preferred micro controllers (e.g., compatible with ESP8266) and single-board computers.

BME680 high-precision sensor can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because of the accuracy in pressure, the sensor can be used to estimate altitude within ±1 meter!

The gas sensor works is by changes in its internal resistance, which is designed to be sensitive to changes in concentration of Volatile Organic Compound (VOC) gases.

It can detect 4 environmental parameters at the same time. Its an ideal choice for scenarios such as weather stations, smart homes, and the internet.
