	~~test~~		= '''WT901B \| AHRS IMU Sensor''' =

			With the WT901B IMU sensor device one can detect acceleration, angle, angular velocity, magnetic filed and air pressure. The both robust and small product is perfectly suitable for smartwatches.


			== Product Features ==
			=== Built-in sensors ===

			Magnetometer: Magnetic Field X Y Z, 3-axis


			[[File:Barometer.png\|50px\|Barometer]]
			Barometer: Air Pressure 1-Axis


			=== Board Dimensions ===
			[[File:BoardSize.png\|100px\|WT901B Size]]
			Size: 15mm x 15mm x 2mm, Weight: 1g

			Tolerance Size & Weight: +/- 0.1

			=== Board Pin Definition ===
			[[File:BoardPinDefinition.png\|300px\|WT901B Pin Definition]]
			* VCC: 3.3-5V input supply
			* RX: Serial data input, TTL interface
			* TX: Serial data output, TTL interface
			* GND: Ground
			* DO: Analog input, digital input and output, PWM
			* D1: Analog input, digital input and output, PWM, connect GPS
			* D2: Analog input, digital input and output, PWM
			* D3: Analog input, digital input and output, PWM
			* SDA: I2C signal line
			* SCL: I2C clock line



			== How to get it to work ==
			=== Connecting to an ESP32 ===
			We need to connect the four pins VCC, RX, TX and GND of the WT901B to the corresponding pins of the ESP32. Therefore, we need to connect WT901B …
			* ...VCC to the power supply (3-5V works) of our microcontroller’s 3.3V pin
			* ...GND to one of the GND pins on our microcontroller
			* ...TX to one of the corresponding pins on our microcontroller
			* ...RX to one of the corresponding pins on our microcontroller

			=== Required Library ===
			* Download and save JY901.h:
			** Go to: '''[https://drive.google.com/drive/folders/1F2oTeQccvxNKxq6nW6isxhYecPMagr8M]'''
			** Download Sample Code zip folder
			** Unzip the folder and navigate to Arduino > Arduino > JY901SerialMega2560
			** Add folder with files to the library folder of your project
			* import library in your main file: #include <JY901.h>

			=== Code Example ===
			<syntaxhighlight lang="python" line='line'>

			#include <Arduino.h>
			#include <Wire.h>
			#include <JY901.h>

			void setup() {
			Serial.begin(115200);
			JY901.StartIIC();
			}
			void loop() {

			//print received data. Data was received in serialEvent;
			JY901.GetAcc();
			Serial.print((float)JY901.stcAcc.a[0]/32768*16);

			JY901.GetGyro();
			Serial.print((float)JY901.stcGyro.w[0]/32768*2000);

			JY901.GetAngle();
			Serial.print((float)JY901.stcAngle.Angle[0]/32768*180);

			JY901.GetMag();
			Serial.print(JY901.stcMag.h[0]);
			}
			</syntaxhighlight>
