Measuring Rotation and acceleration with the Raspberry Pi

Acceleration and rotation sensors are most known from smartphones. The rotation of the device can be detected and can be addressed directly.

With the Raspberry Pi and a Gyroscope / Accelerator sensor it is possible to measure the rotation as well as the acceleration of the 3 axes.
In this tutorial use the MPU 6050 Gyroscope / Accelerator sensor interferfaced to a Raspberry Pi, and reads the values using I2C.

Components:

For this tutorial I have used the following components:

  • Raspberry Pi
  • MPU 6050 sensor module
  • Jumper Cables

Installing the Keyestudio Raspberry PI GPS Plate

This Keyestudio KS0216 Raspberry Pi GPS Plate (shield) features high performance and low power consumption. It utilizes the NEO-6M Module developed by U-blox. The GPS Module is connected through the 2*20 expansion pins of Raspberry Pi. It features a large size ceramic antenna, sending locating information to GPS through the serial port. It can track up to 8 satellites on 50 channels at high speed, and it produces very accurate location data.

Plug the GPS Plate into Raspberry Pi 3. Upload your code to Raspberry Pi 3, and you can find your exact location within a few meters. It also provides you with very accurate time! It can be used in car navigation, personal positioning, fleet management, navigation and so on.Read More

Interfacing DHT11 Raspberry Pi with LCD Readout

Temperature and Humidity are the most common parameters that are being monitored in any environment. There are tons of sensors to choose from for measuring temperature and humidity, but the most used one is the DHT11 due to its decent measuring range and accuracy. It also works with one pin communication and hence is very easy to interface with Microcontrollers or Microprocessors. In this tutorial we are going to learn how to interface the popular DHT11 sensor with Raspberry Pi and display the value of temperature and humidity on a 16×2 LCD screen.

Overview of DHT11 Sensor:

The DHT11 sensor can measure relative humidity and temperature with the following specifications

Temperature Range: 0-50°C
Temperature Accuracy: ±2 °C
Humidity Range: 20-90% RH
Humidity Accuracy: ±5 %
