Onion Omega 2 Setup using Commandline

Omega2, the $5 IoT computer.It is a Linux computer designed specifically for building connected hardware applications. It combines the tiny form factor and power efficiency of the Arduino, with the power and flexibilities of the Raspberry Pi.

The Omega2 is simple, even for people who are just getting started with building hardware.The Omega2 is affordable, starting at just $5.
With the Omega2, we want to lower the barrier of entry and allow everyone to take the leap into hardware development.

February 14th, 2017 No comments

SONOFF TH10SONOFF TH10 /TH16 is a smart switch version of Sonoff which can monitor and set temperature and humidity through the iOS/Android APP eWeLink. Just as the name indicates, the Sonoff TH device supports two current supply specifications: 10A or 16A. It features presetting the range for temperature or humidity. When the temperature or humidity of the environment falls within the range, it will automatically turn on or off the connected devices. It supports three kinds of temperature and humidity sensors AM2301, DS18B20, DHT11

Measure Distance using Ultrasonic Sensor HC – SR04 | Pi4J | JAVA | Raspberry Pi

January 16th, 2017 No comments

HC - SR04This is a simple tutorial showing how to interface HC РSR04  ultrasonic ranging module with Raspberry Pi to measure distance using JAVA. Ultrasonic ranging module HC РSR04 provides 2cm Р400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit. The basic principle of work:

(1) Using IO trigger for at least 10us high-level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning.
