Introducing AirSense, the indoor air quality sensor. The perfect solution for monitoring the air quality in your home or office that is also compatible with ESPHome and Home Assistant. This sensor is equipped to provide accurate readings of indoor air quality, temperature, pressure, humidity, bVOCeq and CO2eq. And if that's not enough, it also features an RGB LED and a buzzer to alert you when the air quality is not optimal. Whether you are concerned about allergies, asthma, or other health issues, AirSense is the ideal choice. Its advanced technology, LEDs and buzzer make it easy to monitor and maintain healthy indoor air quality.

To do this, you must solder the ADDR pad. Addresses: Unsoldered: 0x77 Soldered: 0x76 ESP32 At the heart of the AirSense board is an ESP32-C3F with 4MByte of flash running at a clock speed of 160MHz. It has 2.4 GHz Wi-Fi and Bluetooth 5 (LE) connectivity. Datasheets Gas, Temperature, Humidity & Pressure Sensor - BME680 Addressable RGB LED - WS2812B MCU - ESP32-C3F
