EspEasy and Node Red each offer a number of options for automation. You get even more options if you combine both systems. In the article ESPEasy – Execute commands and […]
WeiterlesenTo be honest, the idea of a 3D printable wind sensor (in technical jargon “anemometer”) has been floating around in my head for a long time. Initially I could have […]
WeiterlesenThanks to the NTP server, ESPEasy is able to call up the time via the WiFi connection. This option is very easy to set up and is described, for example, […]
WeiterlesenWith the Aenmosens_MCU board it is possible to use Anemosens as a stand-alone anemometer, which can be used for long-term observations in remote areas (hence the microSD card slot) or […]
WeiterlesenThe Anemosens sensor PCB is the basis for the sensor assembly of Anemosens, a 3D printed anemometer that I developed for the second version of WinDIY. For this purpose, on […]
WeiterlesenMP3 players, smartphones and USB sticks with 128GB and more memory are now part of everyday life. Storing and transporting music has therefore never been easier. About 30 years ago […]
WeiterlesenThe APDS-9960 is a sensor that can be connected to a microcontroller such as the ESP8266 via the I2C bus. With the help of the sensor it is possible to […]
WeiterlesenThe VL53L0x or its sister / brother, the VL53L1X is a very precise and relatively inexpensive laser distance sensor. With this, distances can be measured almost at millimeter accuracy. In one […]
WeiterlesenThe BME280 is one of the sensors that I use in almost all of my projects. With this sensor one cannot only measure the temperature. The air humidity and […]
WeiterlesenESPEasy can read out a large number of different sensors and/or control actuators (see also ESPEasy – Sensors & Actuators). With the help of the "Rules" it is [...]
WeiterlesenEspecially if your own circuit has a display to show values, the next step is often to connect an interface option. You can connect buttons or switches. A relatively cool […]
WeiterlesenThe PCA9685 is quite a practical IC. This is connected to the microcontroller (eg ESP8266) via I2C and can then control up to 16 individual PWM channels. You can control [...]
WeiterlesenThere are some situations in which connecting an LDR to an ESP makes sense. In this way, the brightness in a room can be measured relatively easily and for little […]
WeiterlesenThe PCA9685 is a PWM port expander. This makes it possible to connect up to 16 LEDs, servos or other components to your ESP8266 and supply them with a PWM […]
