Frequently Asked Questions

What is the operating voltage range for the Elecrow BMP180 module?

The module operates from 1.8V to 3.6V DC. This low-voltage range makes it compatible with 3.3V logic systems like many modern microcontrollers and is ideal for battery-powered applications. Ensure your Crowtail base shield or microcontroller can supply power within this range.

How do I connect and communicate with this BMP180 sensor?

The sensor uses a standard I2C (also called TWI or Two-Wire Interface) communication protocol. Connect the module's SDA and SCL pins to the corresponding I2C pins on your Arduino, Raspberry Pi, or other microcontroller. You will need to use a library (such as Adafruit_BMP085) to read the pressure and temperature data over the I2C bus.

Does this sensor require calibration before use?

No, the BMP180 sensor is factory-calibrated. The individual calibration coefficients are stored in the sensor's internal ROM. Your microcontroller code simply needs to read these coefficients and use them in the calculation formulas to produce accurate pressure and temperature values immediately.

Can I use this module to measure altitude?

Yes, altitude can be derived from the atmospheric pressure readings using the barometric formula. The sensor provides high-resolution pressure data suitable for calculating relative altitude changes. For absolute altitude, you will need to know the reference SEA-level pressure at your location.
