Reliable and compact
The form factor is tiny, which fits perfectly into my weather station enclosure. Data consistency is impressive compared to other cheap sensors I have tried. Highly recommended for IoT projects.

Works but needs careful wiring
The sensor itself is fine, but I initially had trouble getting it to communicate because I was using 5V logic without checking the datasheet thoroughly. Once I switched to 3.3V logic levels, it worked great.

Easy to integrate
I am new to electronics, but connecting this sensor was straightforward. The pinout is clearly labeled on the PCB. Reading pressure and temperature data took less than an hour to set up.

Great for monitoring indoor climate
Using this to track barometric pressure changes in my greenhouse automation system. It detects weather fronts changing before they happen. Very satisfied with the purchase.

Perfect replacement for my old BMP085
This module worked flawlessly with my Arduino Uno. The I2C address matched exactly what I expected, and the library examples ran without modification. Great value for the price.

Good accuracy for the cost
Used this for a small quadcopter project. The altitude readings are stable enough for basic flight control. Just make sure you have pull-up resistors on your SDA and SCL lines if your board doesn't have them built-in.
Q: Is this module compatible with Raspberry Pi?
A: Yes, the BMP180 GY-68 is fully compatible with Raspberry Pi models that support I2C. You will need to enable the I2C interface in the Raspberry Pi configuration settings.
Q: Does this come with header pins soldered?
A: No, the module typically ships with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself or use jumper wires directly.
Q: What is the difference between BMP180 and BMP085?
A: The BMP180 is the successor to the BMP085. They share the same footprint and I2C address, making them direct replacements, but the BMP180 offers lower power consumption and faster conversion times.
Q: Can I use this sensor underwater?
A: No, this module is not waterproof. It is designed for measuring atmospheric pressure in air. Submerging it in water will damage the electronics.
Q: Which Arduino library should I use?
A: The standard 'Adafruit BMP085 Library' works perfectly with the BMP180 sensor. Since they are register-compatible, the library treats them essentially the same.
