What is Geofencing?
Geofencing refers to the automated triggering of action by crossing a geolocated boundary on the earth's surface or in the air. In most cases, the boundary defines a closed surface so that a distinction can be made between inside and outside. For example, a notification can be triggered when entering or exiting the surface. To do this, the observed object must send its position at regular … [Read more...]
How to Make ESP32-CAM IP Camera Access from Anywhere in the World
First and foremost thing to warn - you can not compare the pro-grade IP cameras, something like EZVIZ IP camera with ESP32-CAM IP camera. ESP32-CAM IP camera module is dirt cheap and it is great to increase the number of video capturing devices. I would suggest you have some pro-grade camera to cover the main unsecured points of house/office and use ESP32-CAM IP camera module as an "add-on" to … [Read more...]

For the sake of proper description, we will describe how to wire The … [Read more...]
How to Use PWM in ESP32
Pulse Width Modulation (PWM) is a widely used technique for power delivery. ESP32 has dedicated hardware for PWM. Pulse-width modulation (PWM) of a signal or power source is a technique in which the duty cycle of a periodic signal (a sinusoidal or a square signal, for example) is modified. The duty cycle of a periodic signal is the relative width of its positive part relative to the period. … [Read more...]
ESP32 IoT Setup For Concealed Conduit Wiring
In this article, we will discuss the electrical wiring required to set up a DIY IoT smart control system to control 8 3W spotlights, one ceiling fan and one Indian jhar bati (chandelier lamp).
