sensorMax = sensorValue; } // record the minimum sensor value if (sensorValue < sensorMin) { sensorMin = sensorValue; } } 这种方式下,你做的更多读取可能会根据这个最大值和最小值按比例分配。就像这样: // apply the calibration to the sensor reading sensorValue = map(sensorValue, sensorMin,...

For my computation class, we were asked to give a presentation and some sample code for smoothing an IR sensor in the Arduino environment. I wrote this code that averages the values of the last ten readings. It drops the highest and lowest values, to help control the noise and make sure...

The first two make it easy to read the DHT & MQ sensors (they also support the other variants thereof). The last,EasingLib, provides smoothing functions that help generate better sensor data. The#definestatements in the first section are the only things that should require modification. To us...
Analog Write Mega: Fade 12 LEDs on and off, one by one, using an Arduino Mega board. Calibration: Define a maximum and minimum for expected analog sensor values. Fading: Use an analog output (PWM pin) to fade an LED. Smoothing: Smooth multiple readings of an analog input....

Smoothing can help in cases where sensor readings seem to bounce around. QMC5883L Compass Library uses a rolling average function to store (n) sensor readings and return the average of each axis. This averaging also places smoothing on azimuth and directional output as well. ...
