BMP0180 Atmospheric Pressure Sensor
- It contains the I2C interface.
- its maximum I2C speed is 3.5Mhz.
- this sensor consists of very low noise which is up to 0.02 hPa or 17cm.
- Its size is 13 x 10 mm.
- Analog devises BMP180 Barometric Sensor for Electronics low-power consumption is -0.5 microamps at 1Hz.
- its pressure range is 300 hPa to 1100 hPa or (9000m to -500m).
BMP280 Atmospheric Pressure Sensor
- Power supply: 3-5v (internal low dropout regulator)
- Field range: ± 4800uT
- Pressure range: 300-1100hPa
- Temperature Accuracy: ± 1.0 ° C
- Dimensions: 19.2mm x 17.9mm x 2.9mm / 0.8 "x 0.7" x 0.1 "

- Using Immersion Gold PCB, machine welding process to ensure quality
- Vin- supply pin. Since the image using 3V DC, the board has a built-in voltage regulator
- that receives 3-5V DC and converts them to 3V. To use the module to be powered from
- the same voltage as the Arduino board.
- 3Vo - this is the output from 3.3V regulator. It can provide up to 100mA

- DO switching signal (TTL) output and AO analog signal output.
- TTL output valid signal is low. (When the output low signal is on, it can be directly
- connected micro-controller or relay module.)
- Analog output voltage: the higher concentration, the higher voltage.
- Four screw holes, easy positioning.
- Long life and stability, quick response and resume.
- Input voltage: DC 5±0.2V
- Power: 150mA
- DO output: TTL digital 0 and 1 (0.1 and 5V)
- AO output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
- Dimensions: 32(L) * 20(W) * 22(H) mm
- AO – analog signal output
