The 7Semi BME690 IAQ Sensor Nano Breakout is a compact and powerful environmental sensing module designed for accurate indoor air quality monitoring. Built on Bosch’s advanced sensing platform, it combines temperature, humidity, pressure, and gas sensing into a single small board. This makes it very useful for hobby projects, IoT devices, and smart systems where multiple environmental data is needed in one place.
It is designed to work stable even in tough conditions like moisture and condensation, giving reliable readings over long time. With simple I2C interface and easy connection, it becomes very beginner friendly while still powerful for advanced users.
Features:
• 4-in-1 sensing – temperature, humidity, pressure and gas detection
• Detects air quality including VOC gases and CO2 equivalent
• Compact nano size – easy to fit in small projects
• Low power design – good for battery based systems
• Stable performance even in humid and harsh conditions
• I2C interface – simple communication with Arduino, ESP32, Raspberry Pi
• Supports IAQ index output for air quality monitoring
• Qwiic compatible – quick plug and play connection
• Good repeatability and long-term reliability
