Description
The DS18B20 is a highly accurate, waterproof temperature sensor that is ideal for various applications, including weather stations, aquariums, and industrial monitoring. With a temperature range of -55°C to 125°C and selectable resolution from 9 to 12 bits, it ensures precise readings. The sensor uses a 1-Wire interface, meaning only one digital pin is needed for communication, and it features a unique 64-bit ID for easy identification. Multiple sensors can be connected to the same data pin for efficient data collection.

The MQ-6 LPG Gas Sensor Module is designed to detect LPG and Butane gases with high accuracy. Operating at 5V, this sensor provides both TTL digital and analog outputs, making it ideal for environmental monitoring and safety systems.
The LDR Sensor Module Medium 7mm is an essential component for light/dark detection circuits. Light Dependent Resistors (LDRs) exhibit high resistance in the dark, which can reach up to 1,000,000 ohms. When illuminated with light, their resistance drops dramatically, making them ideal for applications requiring precise light sensitivity. This module is perfect for various electronics projects and automation systems.
