LED Pixel Clock (Clock, alarms, temperature, humidity, atmospheric pressure, and remote monitoring)

thingiverse

The LED Pixel Clock is a four digit clock made up of 30 WS2811 addressable LEDs (8 mm) arranged into a 7-segment display. It based on ESP8266 microcontroller and real-time clock DS3231 (option). BME280 (or DHT22) sensor provides a precise measurement of indoor temperature, humidity and barometric pressure. An Internet connection via Wi-Fi module helps to synchronize time with NTP servers. Data from sensors can be transmitted via MQTT protocol or displayed on popular monitoring service thingspeak.com. Clock adjustment and manipulation is performed via WEB-interface. Features • Always precise time because of synchronization with NTP time servers • Indoor temperature, humidity and barometric pressure measurement • Sending temperature, humidity and barometric pressure data to MQTT and Thingspeak.com server • No buttons – control the clock via WEB-interface from PC, tablet or smartphone • High display brightness • Seven colors to display information • Brightness adjustment • Two alarm clocks • Firmware update via Wi-Fi • Information display on 3 languages: English, Russian, Bulgarian • An option to install different alternative Open Source firmware • Powered via USB • Hackable: Open source hardware and firmware, Displays information read via UART Specifications • CPU: Tensilica L106 32-bit processor (ESP8266) • Connectivity: WiFi 802.11 b/g/n, UART • Peripherals: WS2811 addressable LEDs, BME280 sensor (temperature, humidity and Barometric pressure) or DHT22 (temperature and humidity), UART pins, button, three slots for I2C sensors, buzzer • Compatibility: Arduino IDE, PlatformIO, MQTT, and any modern web browser • Upgradable: The software can be upgraded, either using an USB to UART module and over-the-air (OTA) • Dimensions: 221 mm x 90 mm • Open source Software and Hardware code: https://github.com/Lightwell-bg/LEDPixelClock Required Parts: • Wemos D1 Mini: http://got.by/40d3u7 • RGB LED with WS2811 8mm http://ali.pub/4h4ehf • BME280 Digital Sensor (Temperature, Humidity, Barometric Pressure) 5V: http://got.by/40d52x • TTP223B digital touch capacitive sensor: http://got.by/40d6kz • DS3231 AT24C32 IIC Module Precision Clock http://got.by/42k10g • Active Buzzer http://got.by/42k1sg • You can purchase a PCB with some soldered elements and connectors for connecting the indicator and sensors, or just a PCB and a set of elements for installation https://diy.led-lightwell.eu/product/led-pixel-clock-shield-for-esp8266/ Note: Using the links provided here help to support these types of projects. Thank you for the support. MQTT/Thingspeak LED Pixel Clock can provide your home or office remote monitoring. The device can transmit the data from embedded sensors via MQTT or HTTP protocols. You can receive this data on your smartphone and PC MQTT-clients. Also this data can be transmitted to the popular monitoring service thingspeak.com for graphical format output. Web Interface All clock management is carried out using a web browser. On first power-up, LED Pixel Clock will serve a hotspot called LW-Clock. For clock adjustment and manipulation open a webpage with the 192.168.4.1 address. Within this hotspot you can manually override the time and date, set color, set timecodes of messages output and update software. For Wi-Fi network connection please input its SSID and password. After successful connection LW-Clock will begin to receive and transmit information over the Internet. NTP servers are used to get accurate time. To transmit temperature, humidity and barometric pressure data you can use the MQTT server https://www.cloudmqtt.com/ and the server https://thingspeak.com. Easily Programmable ESP8266 The control center of the device is the beloved ESP8266. It coordinates the Wi-Fi, display, real-time clock (via I2C), tap sensor and buzzer (via digital input) to make everything run smoothly. Arbitrary code can be uploaded from your choice of development environment using the same micro USB cable. Power Supply You must use a power supply 5V with a capacity of 2 A or more.
