About the Homemeteo esp-01 PCB

Homemeteo esp-01 is an open source ESP8266 PCB design by edirab, published on GitHub. It is a 2-layer board measuring 54.2 × 39.3 mm, with 21 components from 17 distinct parts.

Its main chip is the ESP-01v090, from the ESP8266 family. Other key parts include the DHT11, BSS138_4ch, AMS1117-3.3 and Arduino_Nano_v3.x. By type, the board carries 8 resistors, 4 ICs, 3 diodes, 3 capacitors, 2 connectors and 1 module.

It belongs with the iot & wireless designs in this gallery.

From the project

Home meteostation built on ESP 01 and Arduino

Устройство раз в 2 секунды собирает данные о - температуре, - влажности воздуха, - влажности почвы и - относительной освещённости в двух точках

Пакет по локальной сети через wifi отправляется MQTT-брокеру mosquitto, развёрнутом на Raspberry Pi 3B. Скрипт mqtttest.py`, который обработывает callback от брокера, накапливает данные, добавляет к ним временную метку и раз в 10 минут производит запись в базу данных.

Homemeteo esp-01: common questions

What microcontroller does the Homemeteo esp-01 use?

The Homemeteo esp-01 is built around the ESP-01v090, from the ESP8266 family.

How big is the Homemeteo esp-01 PCB?

The Homemeteo esp-01 measures 54.2 × 39.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Homemeteo esp-01?

21 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Homemeteo esp-01 design files?

From the edirab/homemeteo-esp-01 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Homemeteo esp-01 design in my own project?

The repository has no license, so all rights stay with edirab. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Homemeteo esp-01 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
