Compared to the last generation BMP180 barometer sensor, it has a lower power consumption, higher resolution and higher sampling frequency.Īpplication: Enahnced GPS navigation (e.g. It can be applied to enhance GPS navigation & coordinate with IMU sensor to realize indoor and outdoor navigation. Gravity: Analog LM35 Temperature Sensor For ArduinoīMP280 Barometer sensor supports Arduino and can measure both temperature and atmospheric pressure. Gravity: I2C Non-contact IR Temperature Sensor For Arduino We recommand SEN0263 (MLX90614-DCI) for industrial applications. SEN0206 (MLX90614-BCC), due to its large field of view (FOV = 35°), is more suitable for commercial application. The chip itself is a 17 bit ADC and DSP device, giving accurate and reliable results. The MLX90614 is self calibrating and has a low noise amplifier integrated in to the signal processing chip. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing and output module. This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution.
Our latest infrared temperature measurement module is the MLX90614. In recent years non-contact measurement methods have been used for medical, environmental monitoring, home automation, automotive electronic, aerospace and military applications. Additionally, this method of measurement can be read quickly and accurately. By contrast, non-contact measurement uses infra-red radiation to measure the temperature and does not require a direct touch. This can mean longer response times and reading inaccuracies offset by ambient temperature. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. If you see the error message like: “ Could not find a valid BMP280 sensor, check wiring” then you need to change your BMP280 default I2C address in the Adafruit_BMP280.h file.We can divide temperature measurement in to two types: contact and non-contact. You can see the BMP280 Sensor test is running. Serial.print(F("Pressure = ")) Serial.print(bmp.readPressure()) Serial.println(" Pa") Serial.print(F("Approx altitude = ")) Serial.print(bmp.readAltitude(1013.25)) /* Adjusted to local forecast! */ Serial.println(" m") Serial.println() delay(2000) Adafruit_BMP280::STANDBY_MS_500) / Standby time. oversampling / Adafruit_BMP280::SAMPLING_X16, / Pressure oversampling / Adafruit_BMP280::FILTER_X16, / Filtering. bmp.setSampling(Adafruit_BMP280::MODE_NORMAL, / Operating Mode.

While (!Serial) // wait for serial monitorįor (address = 1 address < 127 address++ ) This code will also help you check your sensor working or not. Now, open the serial monitor to check your BMP280 default I2C address. Simply upload the I2C Address Scanner code below.
To check the default I2C address of your BMP280 sensor with Arduino. The following table is the BMP280 sensor Pinout table:Ĭheck the Default I2C address for BMP280 Sensor We can change the default I2C address of the BMP280 module with the solder jumper beside the chip.So, it can be easily interfaced with any microcontroller of your choice. The module features Both I2C and SPI communication protocol.
The BMP280 consumes less than 1mA during measurements.Easy to interface with any microcontroller.Power Requirement 3.3V or 5V (Module comes with built-in LM6206 3.3V regulator).The following table shows the Accuracy and operation range of the temperature, pressure, and altitude of the BMP280 Sensor: Sensor BMP280 Sensor MeasuresĪs I already mentioned above, The BMP280 is a three in one Environmental digital sensor that measures:Īccuracy and Operation Range of BMP280 Sensor It is the successor of the sensors like BMP180 and BMP183.
