Low cost ambient monitoring using ESP8266

Abstract

A different language is different vision of life. Micropython is the open source scripting language and an interpreter that expresses the concepts in fewer lines of codes. This high level language possesses clear and expressive codes which is designed to respond to the actions. It is a lean and efficient implementation of python 3 programming language that comes with the quick language feedback and is optimized for interactive input to run on microcontroller or embedded systems. This functional and dynamic programming language is ported to ESP8266 board. The DHT11 sensor is interfaced with ESP8266 board to sense the ambient conditions like temperature and humidity. The dht module which is confined to DHT sensor is being imported to perform its programming task. The OLED display used here have dimensions of 128×64, it has an I2C interface and can be driven by SSD1306 driver. Firstly, the library for the SSD1306 driver of the chip needs to be imported. The ESP8266 board have two connections, one with the DHT11 sensor to sense the temperature and humidity, and the second with OLED display to show the collected information of temperature and humidity from DHT11 sensor on to the screen. These all are implemented using lean and efficient Micropython language and thus it is easy to control hardware and connected devices using Micropython.
