The ESP32 is a powerful microcontroller with built-in Wi-Fi and Bluetooth, making it an excellent choice for IoT applications. In this project, we will build a weather station using the ESP32 with BMP280 / BME280 air pressure sensor. The BMP280 measures temperature, pressure, and altitude, while the BME280 adds humidity measurement. The sensor data will […]
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 […]
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 […]
The MAX485 TTL to RS485 Modus Module is a popular RS-485/RS-422 transceiver chip manufactured by Maxim Integrated. It’s commonly used in applications where long-distance serial communication is required, such as industrial control systems, building automation, and instrumentation. MAX485 Modbus Module: A MAX485 module typically includes the MAX485 chip along with necessary support components like voltage […]
Controlling home appliances using an Arduino and an IR remote is a popular DIY project that’s relatively straightforward. An infrared (IR) remote control is a device that transmits signals to control electronic devices such as TVs, DVD players, and air conditioners. Working of IR Remote Control: Here’s a basic overview of how it works. Transmitter: […]
