Turta MKR Sensor Shield's specifications are as follows:
Measures temperature and relative humidity.
Temperature: Measures -40 °C to 120 °C temperature with ±0.5 °C accuracy (inside 15 to 40 °C).
Humidity: Measures relative humidity within 0% to 100% range, in ± 3.5% rH, 20 to 80% rH (± 5% rH, 0 to 100% rH)
Factory calibrated.
The sensor uses 0x5F address over the I2C bus for communication and A0 pin for DRDY interrupt.
Measures ambient light, RGB values and proximity. Detects hand gestures.
Ambient Light: Measures ambient light with UV and IR blocking features.
Color Detection: Measures RGBC channels with UV and IR blocking features.
Hand Gesture Detection: Detects left, right, up and down directions within 30cm to the sensor.
Proximity Detection: Detects distance to the object up to 30cm from the sensor.
The sensor uses 0x39 address on the I2C bus for communication and D7 pin for interrupt.
Measures 3 axis acceleration. Generates interrupt on tilt detect.
Acceleration: Measures +/- 8g acceleration data with 1 mg accuracy.
Tilt Detection: Generates interrupt over 0.688g acceleration or 43.5 degrees of tilt.
The sensor uses 0x55 address over the I2C bus for communication and A1, A2, A3 pins for interrupts.
There are two LEDs on-board for user-defined purposes.
Blue LED is connected to the D2 pin, and Red LED is connected to the D3 pin.
There is a micro SD card slot for data logging purposes. The slot is a push-pull style which eliminates external card eject.
The micro SD data line is connected to the SPI bus and CS is connected to D4 pin.
To get maximum performance from your hardware, please make sure you'll meet the following requirements.
This shield works with Arduino MKR series boards.
Board | Compatibility | Notes |
Arduino MKR WiFi 1000 | Not tested | |
Arduino MKR WiFi 1010 | Yes |
To program your device, a recent version of the Arduino IDE should be installed on your computer. Go to www.arduino.cc/en/Main/Software and then select your operating system to download and run Arduino IDE.
A library is responsible for communicating with sensors and other components on board to read values and control them. The shield comes with easy to use methods and examples.
To download the library content, go to github.com/Turta-io/MKR_SensorShield address and download the library files to your computer.
Locate the "libraries" folder inside the Arduino sketch folder.
Copy the library folders inside the "libraries" folder.
To check the installation, start the Arduino IDE and go to File > Examples folder. You should see the library names you copied in Examples folder.
You can find detailed documentation of each module in the subsections.

Problem: The libraries do not communicate with the sensors or the LEDs blink randomly. Cause: There may be an incompatible shield connected between Arduino and the shield. Solution: Please make sure the shield is the only one board connected to the Arduino, and temporarily remove all the connections from any pins. Retry uploading the sketch again.
