server+app+ devices are very power-givinghas been implemented for several days, the device memory is not reduced, the app has not experienced the phenomenon of operation, the server on the view device status is online, good continue to refuel.RT5350 Although the power consumption is a bit larger, but it is large in memory. Run the Linux operating system. Ability to customize very versatile, is a good choice for smart switches.Even though there are a lot of programs that are emerging, such as MT7

The NODEMCU is a compact development board with integrated WiFi and MCU, based on the ESP8266 chip. Forum in http://bbs.nodemcu.com/, source code in HTTPS://GITHUB.COM/NODEMCU.Using the Openscad to make a shell, you can use the 3D printer output, and no longer "bare-Ben".OPENSCAD's original model file is as follows, which can be modified and output on the 3D printer itself.NODEMCU Smart Device, box, Rainproof (vertical mount)//author:[emailprotected],

don't add this resistor. When connecting, of course, all power is turned off. On the relay control side, the 3.3v,gnd of the BBB is connected to the gnd,in signal of the BBB to connect the BBB p9_13 (GPIO number 31). Note, however, that the circuit connection on the other side of the relay must be followed by the manufacturer's instructions. In general, the middle of the relay is connected to the FireWire (positive), the other two ports are normally open negative and normally closed negative.

Arduino MQ135 Gas Sensor first, the wiring The MQ135 has 4 pins, VCC, GND, A0, D0, respectively, where VCC, GND, and A0 are required. The following diagram is a esp8266 wiring diagram. Due to the measurement of the gas value of PPM, it is related to the air temperature and humidity. So we've added a DHT22 here. DHT22 Portal vcc->3v Gnd->g A0->a0 Second, MQ135 library Download Address: https://github.com/zhao007z4/MQ135 After the download is complete,

Simple Primer for Android development and Java language Basics [map]Objective:By the end of last year, I had done a simple smart home, and also realized some simple direct connect and remote smart home. So the simplest communication is released: Smart home Simple Implementation-use ESP8266 simple implementation and app communicationBecause of the small amount of information in this area, the reading volume soared rapidly. There are also a lot of peopl

works well under the MQTT protocol: Owntracks is an open source geo-tracking app. Owntracks periodically reports location information to the server. You can then store and display this information on a basemap, create alarms, and activate your IoT device based on geographic location. Node-red, a browser-based graphical interface that connects IoT devices. You can connect the output of one node to the input of another node, and you can route information between different protocols t
