Water level indicator can be of various complexity levels of different cost. A water level indicator is very much helpful at least in North America and India. Peoples in both of these countries outside the major cities need to pump a natural source of water into a reservoir and then pump to the overhead tank. The Source of natural water can be rainwater, a borewell or a tubewell. This kind of … [Read more...]
What is the Maximum Cable Length Between Arduino/ESP32 and a Sensor
After reading our guide on How to Interface a Piano/Rocker Switch (SPST) With ESP32 Arduino, one reader has asked whether it is possible to keep all his ESP32 with relays and indicators at one room and connect the switches, sensors of the whole house via cables. That is possible to deploy but various hardware components will be required. Also, coding may need some change. I believe that so huge … [Read more...]
How to Interface a Piano/Rocker Switch (SPST) With ESP32 Arduino
We are talking about the regular white colour rocker switches which are commonly used across the globe. They came into the market in the 70s replacing the tumbler switches made up of Bakelite and China clay. They are SPST switches ( read our old article Type of switches to know more). They have different names such as piano switch, rocker switch, decorator rocker switch etc. As because before … [Read more...]
ESPHome VS. Tasmota : When to Use Which and Why
Both Tasmota and ESPHome are nice "platforms" for building a smart home. We have already discussed the getting started part with Tasmota and ESP32. Depending on the use-case, ESPHome may be a better choice. In this article, we will discuss the practical things about ESPHome and Tasmota taking it granted that you are using an ESP32 development board. Why ESP32 over … [Read more...]
How to Work With Tasmota on ESP32
Tasmota is an Open-Source firmware for ESP devices developed by Theo Arends (from the Netherlands). He is also the webmaster of a technology blog with nice tutorials. Tasmota is not written in "Arduino language", however, you will not need to code with Tasmota. It is mostly about uploading the code, hardly changing 1-2 lines for a custom configuration. Your hard work will give you a … [Read more...]
Which IoT Platform is Best for ESP32 Arduino?
There is no single best answer to the question when we want to find the best IoT Platform for ESP32 Arduino. I believe that many of the newbies are not sure why some makers talk about ESP32 Arduino and some talks about Raspberry Pi. ESP32 Arduino and some MQTT service or IoT platform is the easiest way to convert traditional electrical things to smart devices. This is a common need. 90% of our … [Read more...]
Basic Smart Doorbell With IBM Watson IoT and ESP32 Arduino
Before the lockdown, I was building a basic smart doorbell with ESP32 and IBM Watson IoT. The function is easy and practical. We are adding a circuit with ESP32 to an existing battery-operated doorbell. When a person will press the doorbell, you will receive a push notification on your mobile phone. (Long back) I created a video of the basic prototype and uploaded it to YouTube and completely … [Read more...]
What is Vehicle-to-Everything (V2X) is Communication
Vehicle-to-Everything (V2X) is a technology developed in the 2010s in which vehicles communicate with their environment ("x") but also with each other. The data exchange between adjacent vehicles is a special case of Vehicle-to-Everything (V2X) and often called Vehicle 2 Vehicle or V2V communication. The transmission of Car2x is possible in both directions, i.e. from the vehicle to the environment … [Read more...]
How to Stream Live Video From EZVIZ Camera
We have discussed about EZVIZ Security Camera and also discussed How to Protect IP Cameras From Hackers. This article is the base of getting the RTSP feed from your EVIZ camera so that (i) you can play on local computer or PC or Raspberry Pi running VLC player (ii) you can locally save the stream using computer, Raspberry Pi or a smartphone (iii) stream it live to the internet (iv) save on a FTP … [Read more...]
IoT Home Automation: Getting Started
If you have multiple houses and want to remote control the electrical devices from anywhere on this earth with a decent UI then this article is for you. When we need to control just few bulbs or motors then we can use ready to use smart sockets. A DIY alternative to it is using IBM IoT and ESP32 to control the AC powered appliances. These ways are cost-effective, commercial solution provides a … [Read more...]
How to Protect IP Cameras From Hackers
Wireless home security cameras can be very easy to hack, giving criminals the real-time surveillance footage of your home at home. Perhaps you have noticed the sentence in our article on C6CN - "EZVIZ C6CN provides enough security as long as you can patch the common exploits deployed by the intruders". This article talks about some of the common exploits and the way to patch them. Commonly, … [Read more...]
