La medición de la presión absoluta del entorno utilizando un barómetro digital como este tiene algunas aplicaciones interesantes. Al convertir la presión medida en altitud, tienes un sensor fiable para determinar la altura de tu robot, plano o proyectil.
Utilizando un sensor tan capaz como el BMP180 puedes lograr una precisión de 1 m, con ruido de solo 17 cm en ruido de ultra alta resolución. El dispositivo funcionará a solo 0.3uA, lo que significa consumo de baja corriente para aplicaciones alimentadas por batería.
El BMP180 viene totalmente calibrado y listo para usar. Como el dispositivo funciona a través de I2C, hemos añadido las versiones I2C opcionales que se pueden habilitar utilizando el puente de PU (pull up) en la placa para su comodidad y facilidad durante el panadeo.
Utilizando I2C, el dispositivo proporciona presión y temperatura ya que los valores de 16 bits, que se utilizan junto con los datos de calibración dentro del dispositivo se utilizan para proporcionar un cálculo de altitud compensada de temperatura.
Características:
Voltaje de alimentación de 1,8 V a 3,6 V.
Bajo consumo de energía: 0,5 uA a 1 Hz.
Interfaz I2C
Velocidad máxima I2C: 3,5 MHz.
Muy bajo nivel de ruido, hasta 0,02 hPa (17 cm)
Calibrado completo
Rango de presión: 300 hPa a 1100 hPa (+9000 m a -500 m)
El paquete incluye:
1 módulo de sensor de presión barométrica digital GY-68 BMP180

I want a REFUND this sensor didn't work. It has worked before from my previous purchases though. Still this shouldn't be a game of rolling dice to get the good sensor. I deserve what I PAID for!!! >:(

I'm pretty new and still learning the whole Arduino thing, but this was not hard to find a piece of code for and it worked good.

I am not going to change my review of the BMP180 from HiLetgo because the problems I experienced with the BMP180 is fact, however, I have changed the number of stars from one to five because of the outstanding customer service from HiLetgo. Customer service sent me datasheets (which I had studied previously trying to make the BMP180 work) but in addition, HiLetgo has stood behind their product and reputation, they sincerely apologized for the problems I have experienced with their BMP180 and offered a full refund even though the 30 day return period has expired. I wish all companies where as honest, helpful and customer focused as HiLetgo. I will consider purchasing from HiLetgo again, simply because they are an honest seller wanting to do the right thing by their customers.Bought two BMP180, one seems to work accurately, the other reads 10C higher. Swapped sensors from one position to the other and verified it was the BMP180, not my software or hardware. Ordered two more BMP180 from HiLetgo thinking I was unlucky with one sensor, next two BMP180 read 25C high and 210C high. Swapped sensor positions again just to be sure it wasn't my software or hardware and sure enough the faulty BMP180s followed the position swap. The faulty BMP180 pressure also read high by between 20 and 30mb higher than the BMP180 that is working.I will steer clear of anything with HiLetgo stamped on it in future.

I bought this for a project I built as my final project in an Internet of Things class. It works really great, and the price is good. You will have to solder the pins on if you need them.

Tried using it on a Red Pitaya and an Arduino and it didn't work in any of them. The LED doesn't turn on. Don't buy this only because it's cheap.EDIT: This sensor INDEED WORKS. The sensor that does not work is the GPS HiLetgo GY-NEO6MV2.EDIT2: The GPS sensor may be working too.
