ESP8266 based Weather Station with a beautiful look

Posted on by Leave a comment

Dennisv15‘s Weather Station is WiFi enabled using ESP8266 and uses a 2.4″ OLED to display the weather data. It has got one of the most beautiful enclosure made of Acryllic sheet laser-cut in the shape of the Sun and cloud. The shapes are illuminated with different colors based on the weather forecast using RGB LEDs. The firmware is based on Daniel Eichhorn’s popular design of an ESP8266 based weather station that includes measurement of the indoor temperature and humidity using DHT22 and retrieving local forecast data from Wunderground.

Wifi controlled thermostat

Posted on by Leave a comment

This Instructable describes how to build a wifi controlled thermostat that can be programmed over the internet as well as locally through a touchscreen TFT LCD display. The system uses a Raspberry Pi as a central hub that serves web pages so I can control the thermostats from anywhere. The hub also handles all of the wireless communication over nRF24L01+ radio modules (I know I said “WiFi,” and the nRF24L01+ radio module isn’t technically WiFi, but more on that later), and maintains a MySQL database with the thermostat programming as well as any data logging I do. And finally, the hub

ESP8266 weather station with data logging to Excel

Posted on by One comment

Yves Arbour and Rui Santos describes a concept of building a weather station plus data logger using two ESP8266 modules operating in a server/client configuration. The client ESP8266 measures temperature and other sensor inputs and transmits the data to the server ESP8266, which is connected to a PC through a USB-UART bridge. This ESP8266 weather station records the sensor data to a Microsoft Excel sheet on the PC. They used the Things Gateway PC application by Roberto Valgolio to read/write data to the Excel sheets and to generate real-time graphs of sensor measurements.

ESP8266 energy monitor

Posted on by One comment

Brian Dorey designed a standalone home energy monitor using the ESP8266 and a bunch of sensors that to monitor the mains current, the consumption of electric energy, as well as the gas usage. His ESP8266 energy monitor measures the mains current using the iSnail current sensor, which is a self powered AC current transducer that provides a 0-5V dc analog signal proportional to the AC current flowing through it. The output from the current sensor is digitized using the ADS1115 16-bit ADC from Texas Instruments and is fed to the ESP8266 through I2C bus. His electric meter has a blinking LED on the front panel that blinks once for every

ESP8266 timer switch

Posted on by One comment

Here are the instructions for building an ESP8266 timer switch for controlling an AC load connected to a wall socket. It uses an ESP-01 module which is programmed to act as a digital ON/Off timer and controls an external relay circuit. The relay circuit must be isolated from the ESP-01 module using an opto-coupler circuit to prevent any electromagnetic interference from the relay coil which may cause reseting of the ESP8266 device.
