The 5-in-1 Sensor is a combination of three different sensors integrated into a single device:

HTU21D: This sensor is a humidity and temperature meter. It is capable of measuring relative air humidity and ambient temperature with high accuracy. It provides reliable readings and is used in a wide range of applications, from climate control systems to portable devices.

BMP180: This is a barometric pressure and altitude sensor. It measures atmospheric pressure and, from that information, can calculate the approximate altitude. This makes it especially useful in navigation, meteorology, and drone control applications, among others.

BH1750FVI: This sensor is a light intensity meter. Provides readings of the amount of visible light present in a specific environment. It is used in smart lighting systems, portable devices that adjust the screen based on ambient light, and in home automation applications to regulate lighting.

The combination of these three sensors in a single device provides a wide range of environmental and weather information. It can be used in various IoT (Internet of Things) projects, weather stations, environmental monitoring systems and more, allowing users to obtain accurate and simultaneous measurements of temperature, humidity, atmospheric pressure, altitude and light intensity in an environment. certain.

This module combines the following 3 sensors into one easy to use module, all sensors are I2C so minimal connections are required from the module to your arduino
