Control any load over Internet/ based on Temp. & Humidity | SONOFF TH10

SONOFF TH10

SONOFF 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 Source: bit.ly/2lCttDp (ITEAD)

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

uLTRASONI pI

This is a simple tutorial showing how to interface HC – SR04 ¬†ultrasonic ranging module with Raspberry Pi to measure distance using JAVA. Ultrasonic ranging module HC – SR04 provides 2cm – 400cm 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…
