ESP8266 ESP Easy MEGA 2.0

ESP8266 and SMOG part four: Sleep mode for SDS011 in ESPEasy MEGA 2.0

The SMOG sensor project became a bit complex – along with the addition of relay. In the mean time thanks to Gijs Noorlander and yours- since you build, ask and use the sensor – we got updated version of ESPEasy MEGA 2.0 for ESP8266. Why the new blog entry? That’s because Gijs added the included in SDS011 function that when sent over serial connections allows to put SDS011 to sleep. Simple, elegant solution to extend the life and quality of the measurements of the SDS011…

ESP8266 and SMOG part three: sensor protection, cloud upload

Język/Language: Polski English Last time we updated our simple SMOG sensor with display (OLED) and added BME 280 to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. It’s time now to protect our sensor. Why do we need sensor protection? Smog sensor – it’s laser in particular – has a limited lifetime – datasheet states 8000 hours. Both the fan and the laser diode should not work continuously – because of wear…

ESP8266 and SMOG part two: OLED display, measuring conditions

Język/Language: Polski English Last time we build a simple SMOG sensor, it’s time to add display (OLED) and to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. What will you need? Hardware working SMOG sensor from previous entry, the Nettigo store has currently promotion – use the code: DIY_SMOG_15 to get 15% off the price BME280 board – temperature, humidity and pressure – the BME280 and please mind that the board supports VCC of 5V OLED…

ESP8266 and SMOG: Quick and snappy SMOG sensor with WiFi interface – first, basic version

Recently, we built a smog sensor which measures PM2.5 and PM10 ppm particles common in SMOG. This time let’s focus on something easy to do, without deliberations on extending life of the sensor. The Nova Fitness SDS011 (also versions 018 or 015) has proven to be quite accurate, with a good life expectancy, even with nearly theoretical unsupported air humidity above 70%. Today I will try to show you the mobile version of the sensor, using the cheapest elements, and then expand it with a…

Power supply for Raspberry Pi, Orange Pi, ESP8266 – XBOX 360 PSU modification

Proper supply of power is a very important part of our SBC (Small Board Computers) projects. Power supplies with too low current efficiency, instability and lack of filtration – often lead to accidental resets, lack of sensor readings or simply unstable behavior of SBCs. One of the solution is to modify the power supply from Microsoft console – XBOX 360. WARNING: We will work with high currents and high voltage, which requires basic knowledge of electrical engineering. The author is not responsible for accidents and…

Domoticz part 3.1: ESP Easy on ESP8266 – remote and local OLED display with temperature, humidity, light – weather station

Previously we played around the SSD1306 OLED display as side display for Raspberry Pi. The author of ESP Easy – Richard ten Klooster (https://github.com/ESP8266nu/ESPEasy) – recently updated his project to include new sensors, so today we will update our DHT22 enabled remote sensor for Domoticz with display and light metering. Our weather station will get a remote display. I’ve created such bundle of sensors to allow both temperature and humidity measurement small shack for chopped wood but also to light the way to it after…

Domoticz part 2: WiFi remote thermometer for weather station, dual digit precision – it’s ESP8266 for beginners

Last time we installed Domoticz, and soon we will move to Z-Wave, but first – let’s take a look at fantastic little gadget: ESP8266 What is an ESP8266? ESP8266 (also called  ESP here) is a SoC – System on a Chip, which in our case is – CPU/RAM/FLASH with GPIO and WiFi interface – so another mini komputer with wireless interface. You can think of it as scaled down version of Raspberry Pi, less power hungry, but with own WLAN and a lot (minimum 2)…
