5-channel tracing module analog output, analog output and distance, object color related. The stronger the infrared reflection (white), the larger the output, the weaker the infrared radiation (black), and the smaller the output. The closer the detector is to the black line, the smaller the output, so that the distance of the black line can be judged by the output analog. The smaller the value, the closer the sensor is to the black line. Compared with other track sensors that can only output high and low levels, the 5-channel analog output of this product can feedback the distance of the black line, and the feedback is more accurate.

BMI160 6-axis inertial motion sensor
Product introduction
The module uses Bosch's new BMI160 6-axis inertial motion sensor in a MEMS sensor package that integrates the top 16-bit 3-axis accelerometer with an ultra-low-power 3-axis gyroscope. The module can output acceleration data (acceleration values detected by the device in the X, Y, and Z directions) and gyroscope data (the speed at which the device rotates around the X, Y, and Z axes). When accelerometers and gyroscopes operate in full-speed mode, typical power consumption is as low as 950μA, which is only 50% or less of the power consumption of similar products on the market.
Designed for smartphones, tablets, and wearable devices, the Bosch BMI160 includes a built-in smart step counter algorithm that reads the number of steps directly through the registers. The built-in 3-axis acceleration and 3-axis gyroscope enable motion detection such as running and fitness. Module built-in LDO power management chip, VIN supports 3.2~6V wide voltage supply, also has a separate 3.3V interface, compatible with Arduino 3.3V and 5V controller direct drive.
