Dominic Peters shares his project about making an IoT breathalyzer using ESP8266 on Hackster.io. It uses the MQ3 sensor for detecting alcohol concentration on your breath. The ESP8266 reads the sensor data and post it to Cayenne IoT platform so that the data can be recorded and viewed over time from anywhere via internet. The device needs to be portable and durable if it should be used while under the influence. The 11.1 Wh/hr lipo battery provides about 8 hours of continuous use. All the components are stuck to the battery pack with thick double sided tape. I hope this provides

In the past couple years, the ESP8266 platform has flourished dramatically and emerged as one of the most popular hardware tools among electronics hobbyists and IoT enthusiasts. Packed with a 32-bit RISC CPU running at 80 MHz, a fully integrated WiFi radio with TCP/IP protocol stack, serial peripherals (I2C, SPI, and UART), an ADC channel, and general purpose I/O pins, the ESP8266 is the most integrated and affordable WiFi solution available in the current IoT market space. An ESP8266 hardware, like NodeMCU and ESP-01, can directly interface with sensors using its peripherals and upload the sensor measurements to a local

Since its launch in 2014, ESP8266 has revolutionized the IoT space by offering an extremely cost-effective and programmable WiFi-enabled microcontroller to hobbyists and professionals, thereby opening the doors to all kinds of everyday objects and sensors to the internet. In addition, with it’s built-in WiFi capability, the ESP8266 can also serve as a standalone web server on a local network, and can respond to the http GET commands received from an internet browser. This project illustrates how to construct a simple standalone weather web server utilizing NodeMCU development board for ESP8266 and Bosch’s BME280 environmental sensor chip. On receiving the web requests, the ESP8266

First Person View (FPV), also known as video piloting, provides a more exciting driver’s viewpoint for controlling a RC rover by mounting a video camera. This FPV two-wheeled robotic rover is controlled over a WiFi network via any internet browser using an HTML-based control interface. It features an Arduino Uno board that controls the movement of the rover by driving two stepper motors. Arduino gets the WiFi capability with the help of an ESP-01 module (ESP8266 board). The communication between the Arduino and ESP8266 is through a serial interface. An Android smartphone is mounted at the front of the rover for live
