You can download the codes: Download codes here or check below: Code 1: LCD i2c New_Liquid_Crystal library: Download LCD i2c library here Wiring: DHT11 (3 pins version) wired with LCD i²c and an Arduino The LCD I used is a I2C version, there are the standard versions but they require a lot of pins, and also in this case you’ll need another library and code functions. The LCD i2c is totally optional but usually used with this module as a classic learning project, in case you don’t know how to use one check here: LCD i2c tutorial.

DHT 11 (obvious 😃 ) note here that I’m using 3 pins version there are 4 pins one.

SHT 21/HTU 21 – Measure Temperature and Himidity with Arduino + OLED/LCD.

Measuring temperature and humidity using AM2320 (DHT12 ?) i2c sensor.

Measure Temperature / Humidity and Heat Index using DHT 21 (AM 2301) + Arduino + LCD.

Measure temperature/humidity using DHT22 + LCD i2c + Arduino.

In this tutorial we gonna see how to simply use the DHT11 module, It’s a module that can measure ambient temperature 0-50☌ and humidity up to 95% RH ( Relative humidity), it’s very good for Home Automation projects or DIY projects for daily use.Īlso there are a lot of modules that have the same function as this one, you can check them here: To interface BMP180 Sensor with Arduino to measure Pressure & Temperature copy the code below and upload it to the Arduino UNO Board.Before proceeding, if you need to buy DHT11 sensor, check Seeedstudio by clicking here ! In this case, it is sufficient to measure the temperature only once per second and to use this value for all pressure measurements during the same period. The sampling rate can be increased up to 128 samples per second (standard mode) for dynamic measurement.

These constants can be read out from the BMP180 E2PROM via the I2C interface at software initialization. After converting time, the result value (pressure or temperature respectively) can be read via the I2C interface.įor calculating temperature in ☌ and pressure in hPa (hecto Pascal), the calibration data has to be used. The microcontroller sends a start sequence to start a pressure or temperature measurement. The BMP180 delivers the uncompensated value of pressure and temperature. The BMP180 consists of a piezo-resistive sensor, an analog to digital converter and a control unit with E2PROM and a serial I2C interface. We will use an Arduino board to read the temperature and barometric pressure measurements from the BMP180 sensor and display the data on 16*2 LCD.

Here we will Interface BMP180 Sensor with Arduino. The raw measurements of pressure and temperature from the BMP180 sensor has to be compensated for temperature effects and other parameters using the calibration data saved into the EEPROM. It consists of a piezo-resistive sensor, an analog to digital converter and a control unit with EEPROM and a serial I2C interface. It can also measure altitude and temperature. It has a measuring range from 300 to 1100hPa with an accuracy down to 0.02 hPa. It measures the absolute pressure of the air around it. Because pressure changes with altitude you can also use it as an altimeter.

It is an ultra low-power digital temperature and pressure sensor with high accuracy and stability. This precision sensor from Bosch is the best solution for measuring barometric pressure and temperature. Interface BMP180 Sensor with Arduino to measure Pressure & Temperature: Components Required: S.N.īMP180 Baromteric Pressure Sensor from Bosch Here is a demo to show you how to read the barometric data from this Grove – Barometer Sensor (BMP180). With Arduino, a Barometric condition is one of the criteria used to predict coming change in weather and deduce altitude above sea level. Go through this link to learn the advance version of this project:īMP180 for Altitude, Pressure & Temperature Measurement The BMP180 Sensor is a barometric sensor capable of measuring pressure, temperature & altitude as well. In this post, we will learn how to Interface BMP180 Sensor with Arduino to measure Pressure & Temperature. 2 Interface BMP180 Sensor with Arduino to measure Pressure & Temperature:.
