Let’s learn how to build an Environment Monitoring System with Arduino, ESP32, Soil Moisture Sensor, and DHT11 Sensor. Monitoring environmental conditions such as soil moisture, temperature, and humidity is essential for applications in agriculture, gardening, and climate control. We’ll cover the working principles of these sensors, how to interface them with Arduino or ESP32, and […]
Let’s get started with how to build a smart Water Quality Monitoring System using TDS sensor and ESP32 or Arduino. A TDS (Total Dissolved Solids) Sensor measures the total amount of dissolved solids in a liquid, typically water. Dissolved solids include inorganic salts and small organic substances. The measurement is expressed in parts per million […]
Drone sensors are the most critical and indispensable part of drone systems. They are like the eyes, ears, and tentacles of drones, responsible for collecting environmental data in all directions. These data are like keys that help drones unlock a variety of complex and critical functions such as stable flight, precise navigation, and clever obstacle […]
Let’s designing a PIR motion sensor circuit that uses a Passive Infrared (PIR) sensor to control a buzzer through a 555 timer for motion detection applications. Here’s a step-by-step guide to creating this circuit: Working Principle of PIR Motion Sensor: A Passive Infrared (PIR) motion sensor detects motion by sensing changes in infrared radiation. Here’s […]
Let’s see how to interface rain sensor with Arduino, a rain sensor, also known as a rain switch or rain detector, is a device used in various applications to detect the presence of rain and trigger a response. The basic principle behind a rain sensor involves detecting changes in conductivity or capacitance caused by the […]
Creating an altimeter and environment sensor using BME280 and ESP32 microcontroller can be a fun and educational project. The BME280 is a sensor that measures temperature, pressure, and humidity, making it perfect for altitude measurement. Here’s how you can build it: Components Needed: ESP32 development board BME280 sensor module Breadboard and jumper wires OLED display […]
