I have found some one who sais he has i running. this is his blog: here and the corresponding github files: here Difference is that he has MHZ19 and i have MHZ19B sensor. Where the TX and RX are on different pins. My wiring ...

Yet another CO2Ampel based on an ESP8266 (Wemos D1 mini) to continuously measure CO2 concentration indoors with a SCD30 CO2 sensor accompanied by a BME280 for temperature, humidity and air pressure readings. Current air condition (good, medium, critical, bad) is shown using a NeoPixel ring with WS2812 LEDs illuminating the device in either green, yellow or red. Unlike other devices this …

WeMos D1 mini is an ESP8266 based board that can be programmed with Arduino IDE. In this blog I will describe how to make a simple WiFi based server that is being powered by a LiPo battery and shows temperature and humidity inside your browser window. A while back I have ordered this board together with a couple of battery shields and a LiPo battery. They came packed with multiple pin ...

20190203· My initial idea was to make a compact device with as much sensor as I can buy. But first I need to try out how the D1 mini works with the Tasmota rom. So I opend up the wiki page and started to add items to my list: Wemos D1 mini AM312 motion sensor HCSR501 motion sensor BME280 temp.humiditypressure sensor TSL2561 light sensor (its a 3 pack 1 would cost nearly the same) …

For battery powered sensors, I directly soldered battery holder and DHT temprerature sensor to wemos D1 mini board. Add Tip Ask Question Comment Download. Step 2: Setup Blynk. Install blynk on your phone and create there new project with 2 devices. For each device you will receive individual access codes.

Steep price difference, but hey, at least I got it! All …

20210502· This D1 mini module is a mini WIFI board based on ESP8266MOD. This board contains 11 digital I/O pins, all pins have interrupt / PWM / I2C with a microUSB connection for power and data connectivity. This also has one analog pin for analog inputs. WeMos D1 Mini board is compatible with Arduino IDE.

20170117· Measure Air quality with MQ135 and ESP8266 Wemos D1 mini. As the MQ135 is not really suited as a CO2 sensor (See my previous blog) and I still wanted to use it, I will use it as an air quality probe on an the title mentioned I will use an ESP8266 connected to my local WiFi router for this to send the data to The ESP8266 I use is the Wemos D1 mini.

20161018· And, for the record, the Mini is taking code from the arduino IDE superbly. I was able to get an HTU21D sensor working pretty easily on pins D1/D2 so I decided to give it a try with the CO2 sensor. This is the ''provided'' code from the company, and I''ve changed the pins to reflect D1/D2 (though I would prefer to use other pins if possible)

The USB port of the Wemos D1 mini is plugged directly on a small power adapter. The usb cable can also be used to upgrade the firmware as no OTA was implemented on this project. All in a "sensor box" Like almost everything else, directly from China, I found an enclosure designed for sensors (or thermostat?) which was the right size to fit ...

Wemos D1 Mini Soldering onto PCB. The next step is to solder the D1 Mini onto the PCB. Please make sure you solder it the correct way. The micro USB port needs to face outwards. You can also compare the PIN labels on the PCB with the ones on the D1 Mini. You can either solder the D1 Mini directly onto the PCB or use the pin headers as a socket. If you solder it directly, please leave a small ...

Please follow the DIY Kit Build Instructions but you only need to solder the Wemos D1 mini and the CO2 sensor. The RGBLed can fit on top of the D1 Mini the same way as the OLED display of the kit. However you need to adjust the RGB shield to use pin D8 instead of the default D4. To do this, add a solder bridge at D8 and remove the connection on D4. Once your built is done, it should look like ...

In this example we connect a PIR module to a Wemos Mini. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. This is from Wikipedia and sums up the operation of a PIR nicely. An individual PIR sensor detects changes in the amount of infrared radiation impinging upon it, which varies depending on the ...
