SmartElex BME680 Breakout - 4-in-1 Environmental Sensor for Air Quality Projects

The SmartElex BME680 sensor breakout is the only module you need for complete environmental monitoring. Measuring temperature, humidity, barometric pressure, and VOC gas resistance in a single package, the BME680 is used in everything from indoor air quality stations to high-altitude weather balloons. At Rs.747.45 with a 7-day warranty on manufacturing defects, it ships 1-5 days from Bengaluru with COD + UPI.

Why choose SmartElex over clones

Generic BME280 boards measure only temperature and pressure. The BME680 adds VOC gas sensing - critical for air quality monitoring. SmartElex uses the genuine Bosch IC with a proper PCB layout, onboard 3.3V regulator, and level shifting, so it works directly from a 5V Arduino or a 3.3V ESP32 without modification.

Real-world projects

1. Indoor Air Quality Monitor

Log CO2 equivalent, humidity, and temperature on an ESP32 with an OLED display. Link with our 0.96" OLED.

2. Portable Weather Station

Combine with a GPS shield for geo-tagged altitude and pressure logging on SD card.

3. Smart Greenhouse Controller

Trigger irrigation and ventilation based on BME680 humidity + temperature readings on Arduino Mega.

How it compares

The BME680 is the only Bosch sensor with gas sensing - the BME280 has no VOC capability. The SmartElex BME680 from The Engineer Store is Rs.747.45 - cheaper than theengineerstore.in's Rs.748 - and ships with a full 7-day warranty on manufacturing defects and COD from Bengaluru.

FAQ

Q: Does the BME680 need a library to work with Arduino?
A: Yes. Install the Adafruit BME680 library from the Arduino Library Manager. Full I2C and SPI examples are included.

Q: Can I use it with Raspberry Pi?
A: Absolutely. Use the Adafruit CircuitPython BME680 library over I2C on any Raspberry Pi model.

Q: What is the I2C address?
A: Default is 0x76; set SDO HIGH for 0x77 to use two sensors on the same bus.

Q: Does it measure CO2?
A: It measures VOC gas resistance used to estimate an Indoor Air Quality (IAQ) index, not absolute CO2 ppm directly.

Q: Is a 7-day warranty on manufacturing defects included?
A: Yes, all SmartElex modules from The Engineer Store carry a 7-day warranty on manufacturing defects against manufacturing defects.
