ESP8266 Weather Station / Temperature Sensor

Posted on 2019-06-18

Introduction

ESP’s are great to give your sensors the possibility to extract the sensor data, because of the on-board WIFI chip, which can connect to your network.
Imagine you have multiple sensors, and you would like to access the measured data and show it in Home Assistant. You can either spin up a web server on your ESP and pull the data or send data from your ESP to your Home Assistant.

The advantage of the push strategy is power saving through deep sleep mode of ESP, which will be explained later.

Components

  • The KY-013 Analog Temperature Sensor
  • ESP8266 from mine previous post

In my case the + and - pin label was incorrect and I had to swap them. So that the orange wire is attached to + (and not -).

ESP8266 Overview - Arduino IDE Setup

Posted on 2019-02-03

ESP8266 is a low cost (2-3$ in begin of 2019) WIFI microchip with a 80/160 MHz CPU, which will be used for a lot of DIY projects.
If you are looking for more powerful microchip, or you need Bluetooth capability, check out the successor ESP32.

I bought the “D1 Mini” model of ESP8266 with 4MB flash (you can get them e.g. here).

Note: It is not the WeMos D1 Mini, but a copy of it. The PIN diagram is the same, which you can find here.
