BMP180 Based USB atmospheric Pressure Monitor

BMP180 Based USB atmospheric Pressure Monitor

Dilshan R Jayakody designed a BMP180 sensor module based on PIC18F2550 MCU to test out it’s performance. He writes:

We initially developed this USB atmospheric pressure monitor to study some operating characteristics of Bosch BMP180 sensor. BMP180 is low cost sensor to measuring barometric pressure and temperature. According to the data sheet this sensor can use to measure pressure ranging between 300hPa to 1100hPa. This sensor is introduced couple of years back but still it is popular due to lower cost and simplicity.

We did this unit to test BMP180 sensor more accurately and to study it’s behaviors. This unit is based on PIC18F2550 microcontroller and the main reason to select this MCU is because of it’s built-in USB 2.0 interface.

Dear Mike
Thank you very much for this informative article. I would like to add a couple of points here. Bosch BMP180 sensor is successor of the SMD500. This has product has many Practical applications like
Enhancement of GPS navigation (dead-reckoning, slope detection, etc.)
Leisure and sports
Weather forecast
Vertical velocity indication (rise/sink speed)
