Build your own long-range weather station with Lora GPS anemometer module
In this tutorial we will see how to create a weather station, for places where there is no internet access with LORA modules, GPS, Temperature and humidity sensor DHT11, but I recommend the DHT22, we will also work with an anemometer to measure the wind speed, as a controller of the system we will use […]
Dual Synchronized Radio Frequency Control for Motor Lights and more
In this tutorial we will see how to do a synchronized radio frequency control, since one control can control the other. With APC220 modules, which according to the manufacturer can reach a distance of up to one kilometer, under appropriate conditions, are transparent radio modules, since everything that it sends through the serial port, is […]
How to make an automatic fish feeder
In this tutorial we will see how to make an automatic fish feeder with arduino nano, a 28byj-48 stepper motor with its respective controller. In addition, a real-time PSTN or clock is included, ds1307 although it also serves the ds3231, which will allow us to configure the system to do the food download at the […]
How to turn on lights with telegram and esp32 from anywhere in the world
In this tutorial we will see how to make a system that allows us to turn on lights with telegram, from anywhere in the world, just by typing a command. To do this a dual channel relay module will turn on two 110V/220V bulbs, the esp32 will connect to our Wifi network and by means […]
Motion detector with light, esp32 and telegram notifications
In this tutorial we will see how to make a motion detector system, with a PIR sensor, a relay module, to connect a 110V/220V focus, an esp32 that will connect to our Wifi network and send alert notifications, by messages through the telegram messaging service, when the PIR sensor detects a movement. You may be […]
