Description
MPL3115A2 Altitude-Pressure Sensor BreakoutSEN 11084 Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24 bit ADC and transmitted over I2C, meaning it's easy to interface with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The device
SEN-11084
Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24-bit ADC and transmitted over I2C, meaning it's easy to interface with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The device also provides 12-bit temperature measurements in degrees Celsius.
This breakout board makes it easy to prototype using this tiny device by breaking out the necessary pins to a standard 0.1" spaced header. The board also has all of the passive components needed to get the device functioning, so you can simply connect it to something that talks I2C and get to work!

Don’t waste your money. Your dog will be eating plastic…
Color: Pink
My dog ends up chewing the plastic ends which is destructible, so I took it away from her. She loved it though and the colors are cute. But eating plastic isn’t ever a good thing. I recommend sticking to actual bones or something else, not this.

Cute toy for small dogs!
Color: Pinata Dog Toy
My dog is obsessed with this toy. This does not have a squeaker in it which is great cuz she doesnt like them. The crinkles and rope seem very durable. She did eat the tail very quickly but overall its held up well! Great tug toy for a small dog or puppy!
