Problem: We need to track environmental variables in our laboratory to identify parameters that affect our measurement results
Solution: We read out sensors using Arduinos and transfer the sensor data to PCs for storage and analysis. We programmed sensors to analyze temperature, humidity, air pressure, acceleration, and motion. For some sensors (e.g. temperature sensors), the program just involves reading sensor values. For other sensors (e.g., the BMP180 pressure and temperature sensor), a library is required to handle the communication with the sensor. Some programs were written in older Arduino IDEs and they may have to be adapted to work with the new IDE.

|Pressure_sensor_BMP180: Minimal p,T readout program for BMP180 via I2C.
pTH_sensor_BMP180_SHT15: p,T readout from BMP180 via BMP180n library and hum,T readout from SHT15 via the SHT15 library. The program saves data to the Adafruit SD shield (SD library) and accesses the real time clock on the shield via the RTC_I2C library.
pTH_sensor_BMP180_SHT21: p,T readout from BMP180 via BMP180n library and hum,T readout from SHT21 via the SHT21 library. The program saves data to the Adafruit SD shield (SD library) and accesses the real time clock on the shield via the RTC_I2C library.
