ESP8266 FIRMWARE TASMOTA SOFTWARE
In addition, there is no programmable ROM in the SoC, meaning that any software must be stored on the module’s SPI flash.
Each of the eight exposed pins has specific functions, as suggested by their name: Pin # Of note, it exposes only four GPIO pins to interface with other devices–namely, URXD, UTXD, IO2 and IO0–and it is powered via 3v3 DC to the VCC and GND pins. The ESP-01 is a cheap and very small WiFi module developed by Ai-Thinker that is based on the ESP8266EX microcontroller unit (MCU) by Espressif: Top Overview of the main hardware components ESP-01 3W on average, with 1W peaks) and can be connected to USB 2.0 ports via USB adapters that have a built-in voltage regulator.įurthermore, because the unit will draw power from standard USB ports, it can be connected to most power banks to create a mobile/remote ambient sensor. Specifically, it requires very little energy to operate (roughly. In addition, because interfacing via the USB connection might not always be possible, owing to proprietary and closed-source firmware, the DIY project should be able to transmit data wirelessly instead.įortunately, the ESP-01 WiFi module meets all such requirements. However, the most common type of USB port available ( USB 2.0) usually delivers a maximum of 500mA at 5V ( 2.5W), which constraints the type of projects that could reasonably use such ports as power supply.
ESP8266 FIRMWARE TASMOTA PC
Over the years, I have started noticing that multiple devices spread across the household (e.g., smart TVs, sound systems, wireless routers, PC towers and laptops) had one or more USB ports that could be used to power a few DIY electronic projects. But please observe the official mounting instructions for the BME280 sensor before printing your case because the heat generated by the ESP-01 and its USB adapter can affect the sensors. However, if you designed a case to house this particular project, get in touch with me and I will feature your case here. Next, I talked about the hardware and software components, and finally, at the end, I covered the assembly of it all to create a functional unit.īecause this is such a low-profile project, I do not ever bother printing a case for it. The article started with my motivation for this particular project. This is a great project for anyone who wants to get started on building their own Internet of Things (IoT) devices.
ESP8266 FIRMWARE TASMOTA HOW TO
In this first iteration of the series, I described how to wire and configure a BME280 to the tiny ESP-01 (or its successor, the ESP-01S) to create a cheap (less than US$6), low-power (less than 1W), and low-profile (less than 5cm long) environmental sensor that provides temperature, humidity, and relative pressure measurements to home automation systems via MQTT.
ESP8266 FIRMWARE TASMOTA SERIES
This is the first article of a Do It Yourself (DIY) series in which I describe simple electronic projects that make use of an ESP8266/ ESP32 board running the Tasmota firmware to integrate various modules into a home automation system, such as Home Assistant.
