Fermion - ENS160 Air Quality Sensor - DFRobot SEN0515

The sensor module is based on the ENS160 chip, which is used to monitor indoor air cleanliness. It processes IAQ (Indoor Air Quality) data such as TVOC (Total Volatile Organic Compounds), eCO2 (equivalent CO2), AQI (Air Quality Index). It is powered by 3.3 V. The module consumes very little power and is very accurate. It communicates via I2C and SPI interfaces.

Connection diagram of ENS160 air quality sensor to FireBeetle ESP32-E. On the left is the connection for I2C and on the right for SPI.

The diagram shows the connection of the module to the FireBeetle ESP32-E board. The sensor uses I2C or SPI interface for communication. Pinouts of ENS160 air cleaner sensor:

• 3V3: power supply
• GND: ground
• SCL: I2C bus clock line
• SDA: I2C bus data line
• SCK: SPI bus clock line
• SDI: SPI bus data input
• SDO: SPI bus data output
• CS: SPI selector
• INT: interrupt pin

The sensor module is compatible with Raspberry Pi, connect it as per the diagram. The sensor uses I2C or SPI interface for communication.

• Warm-up time less than 3 minutes, fast data reading
• Accurate data reading due to high quality circuitry
• Environmental data reading: TVOC, eCO2, AQI
