Replaces / Cross-Reference Part Numbers
- BME280
- GY-BME280
- Functional upgrade for BMP280, BMP180, and BMP085 sensors (adds humidity sensing and higher precision).
Compatibility & Fitment
- Designed for use with microcontrollers such as Arduino, ESP32, ESP8266, and Raspberry Pi.
- Suitable for a wide range of applications:
- Weather stations and environmental monitoring
- Indoor climate control and HVAC systems
- Altimetry and barometry for drones or personal navigation
- Home automation projects
When to Replace
- Sensor fails to provide readings or sends intermittent data.
- Readings for pressure, temperature, or humidity are static or inaccurate.
- Module is no longer detected on the I2C or SPI bus.
- Physical damage to the PCB or sensor element is visible.
Installation Tips
- Connect VCC to a 3.3V or 5V power supply and GND to ground.
- For I2C mode, connect the SCL and SDA pins to the microcontroller's corresponding I2C pins.
- For SPI mode, connect SCK, SDO, SDI, and CS pins to the microcontroller's SPI interface.
- To ensure accurate temperature data, position the sensor away from heat-generating components.
- Protect the sensing element from direct exposure to dust, liquids, and physical contact.
- Refer to the component datasheet for I2C addressing and register information.

Cute toys
Color: Purple & Yellow & Green
Cute and great squeaky toy but if you have a rough chewer on your hands, then they are easily destructible.

Fun but easy to destroy
Color: Green & Yellow & Blue
We foster puppies and go through a ton of toys. These soft, latex toys are great for non-super chewers, whether puppies or small to medium dogs. Our 20-week-old foster puppy has had a great time with hers, which still squeaks. She is fairly gentle and enjoys squeaking her toys, but is not destructive. If you have super chewers, these will not last for even a minute. One of our dogs got a hold of one toy after a few days and demolished it in literally 6 seconds. The price is quite high for toys if in this style, as you get three of them for $16, and typically you can get similar toys for a much lower price, but they do have a great squeak and the long necks have really pleased the puppy. I think that for the right dog, these would be great, and I would recommend them, but avoid them if your dog likes to destroy their toys because they are terribly easy to rip apart.
