DHT11 is a quite simple to use component. It has low precision and is quite slow to read, but is good enough for most ambient control applications. It consists of a resistive humidity sensor and a Negative Temperature…

Using BME280 sensor for Humidity, Barometric Pressure and Temperature.

I’m interested in measuring these parameters (Humidity, Barometric Pressure and Temperature) to collect information using many low costs sensors along the Geophysical Network for several purposes.

So I’m experimenting w…

Arduino I2C-LCD Display Project with Malpartida Library

2017-10-202017-10-30 Enrique Latorres

[multilanguage_switcher] When trying to connect an LCD Display to your Arduino project, a clever solution is to use an I2C-LCD adapter. In this case the FC-113 IIC/I2C serial interface adapter module for 1602 or 2004 LCD Display. This will decrease the number of pins used in your Arduino board, leaving place for other sensors and actuators. The connection between the LCD Display and the I2C Module is quite straight forward. simply connect pin n of LCD to pin n (1 to 1, 2 to 2, and so on) of Serial Module…

I’m experimenting with several accelerometer/gyroscope sensors for different purposes, from robotics, drone equilibrium, vibration control, building oscilations, to seismicity.

In this case we are using the the…

Testing Lolin NodeMCU V3 esp8266

2017-10-172017-10-19 Enrique Latorres

[multilanguage_switcher] I’m testing Lolin NodeMCU V3 esp8266. This is a tiny microcontroller with embeded wifi. The model we are trying has 1MB of flash ram plus 8k of dynamic ram. These are quite a lot for many purposes. I’m using Arduino just for ease. But it’s got a Lua framework, this is that you can make Lua scripts upload them to the NodeMCU, link it to the init.lua script and run. I’m not going to show the Lua example in this post, but the Arduino IDE example. The Arduino IDE…
