XL4016 Step Down Module 300W 10A

A flame sensor module is an electronic device used to detect the presence of flames or fire. It is commonly used in various applications such as fire detection systems, safety equipment, and industrial processes. The module typically consists of a sensor and supporting circuitry that helps in flame detection.
The flame sensor module works based on the principle of infrared (IR) detection. It uses an IR receiver to detect the infrared radiation emitted by flames. When a flame is present, it emits IR radiation that falls within a specific wavelength range. The sensor module is designed to detect this specific range of IR radiation and trigger a response.

The HC-05 is a popular Bluetooth module commonly used for wireless communication between electronic devices. It is based on the Bluetooth 2.0+EDR (Enhanced Data Rate) standard and is designed for easy integration into various projects.

The module allows devices to establish a Bluetooth connection and communicate wirelessly over short distances, typically up to 10 meters. It supports both the Bluetooth Serial Port Profile (SPP) and the Bluetooth Master-Slave mode, making it compatible with a wide range of devices and applications.
