ESP8266. Outdoor weather station

espressifText herein is the continuation of my previous work with ESP8266-07 WiFi module. That work was related to connecting the ESP with humidity/temperature sensor (DHT22) and pressure sensor (BMP180). The weather station prototype described here consist of set of ready-to-use modules: ESP8266-07, DHT22, BMP180 and DC-DC converter module (built on LM2596HV chip). All components mentioned above was purchased in shop. As enclosure was used standard box with flanges from Gainta (model G203MF).


Outdoor weather station

The described device includes the next sensors – DHT22 and BMP180 which allows to measure such parameters of an weather condition as temperature, humidity and pressure,

  • Pressure 300…1100 hPa (30…110 kPa)
  • Temperature -40…+80 °C
  • Humidity 0…100%

Power supplies to this device with AC-DC adapter 220V-9v(5V), voltage from such adapter is additional converted with DC-DC converter to the level 3,3V.

ESP8266. Hello world

espressifFirst try with WiFi module ESP8266 (ESP-07) produced by Espressif. Actually first trying to use this module I have performed at last year. But then my experiments with module end with some firmware malfunction. At this time all goes more or less fine. The first thing which I made after purchasing the module was upload a NodeMCU firmware. This firmware allows me to use the lua-scripts for programming the ESP8266. Since previous year NodeMCU has a lot of changes. A lot of sensors have a support  which is built-in NodeMCU. So data from these sensors could be read with use embedded functions without any third-party libraries.
