The LoRa technology penetration around the world is increasing and because of their ability to run on very minimal power, LoRa devices can be ideal for battery-intensive applications like remote weather monitoring, remote sensing, and tracking.
ESPHome is a simple yet powerful system that allows users to control ESP boards using YAML configuration files. It allows users to quickly and easily build custom firmware for sensors and devices without any programming skills.
Today we will be working on a Water level indicator whose data can be monitored through a webpage over a local area network. The water level will be detected by using an ultrasonic distance measurement sensor.
HC-SR501 Motion Sensor usually known as the PIR sensor is used in many kinds of Security Alarm Systems and Motion Detector systems. Instead of emitting infrared signals, it absorbs IR signals and that’s why it is called PIR (Passive Infrared) Sensor.
A definitive and comprehensive vehicle accident and rash driving identification and alert system using NodeMCU. Unlike other projects across the internet, it has a fully functional and independent circuitry.
After the COVID-19 outbreak, the contactless temperature measurement devices are getting very popular and most of them use the infrared temperature sensor. This device measures the temperature of the person without any physical contact.
