BME680 Stainless Steel Probe Wire 1 Meter - I2C Interface

The probe's core sensor operates from 3.0V to 3.6V DC. For systems with a 5V supply, a logic level converter is required on the I2C lines (SDA, SCL) to avoid damaging the sensor, although the power pin must remain within the 3.0V-3.6V range.

Connect the probe's 4-wire cable: VCC (3.3V), GND, SDA (I2C Data), and SCL (I2C Clock) to your microcontroller. Use standard I2C libraries (e.g., Adafruit_BME680 for Arduino) to read temperature, humidity, and pressure data. The sensor has a default I2C address, typically 0x77.

The stainless steel housing provides robust physical protection and corrosion resistance. However, for submersion or high-pressure washdown applications, verify the IP rating of the specific cable gland and probe seal, as the standard unit is designed for environmental durability rather than full waterproof immersion.

The integrated BME680 sensor provides high accuracy: typically ±0.5°C for temperature and ±0.3% relative humidity (RH) under specified conditions. Accuracy can be influenced by external factors like airflow, thermal gradients, and extreme environmental conditions outside its calibrated range.

Yes, but the standard BME680 has a fixed I2C address. To use multiple sensors on one bus, you will need an I2C multiplexer (e.g., TCA9548A) to manage separate channels, or physically enable/disable sensors using a GPIO pin to control their power or bus connections.
