Procedure for using I2C sensors¶
- Scan for Sensors
- Click to monitor via analog gauge
- List of I2C sensors supported thus far (Minimal data logging. Configuration options via the graphical utility might be incomplete)
- MPU6050 3 Axis Accelerometer, 3 axis Angular velocity (Gyro)
- MPU9250 9-DOF sensor
- MS5611 : 24 bit pressure and temperature sensor. Can resolve 15cm height variations
- TSL2561 Luminosity measurements
- BMP280 Pressure and Temperature sensor
- MCP4725 Single channel DAC
- PCA9685 PWM controller
- MLX90614 Passive IR
results from a Malus Law experiment carried out using a TSL2561 Luminosity sensor, a laser diode, two pieces of polarizers ripped out of an LCD screen, and a hollow shaft stepper motor
The analyzer was rotated step by step, and light intensity was recorded using the light sensor. It confirms maximum transmission when both polarizer and analyzer are parallel, and minimum when orthogonal. It does not go to exactly zero because ambient light was not fully blocked by leveraging a dark room. However, curve fitting showed that the shape was sinusoidal (cos^(theta))
