Laser Diode LM-1 650nm 5mW

This DHT11 is a sensor that combines both temperature and humidity sensing capabilities in a single package. It is not available as a standalone temperature-only or humidity-only sensor.

The temperature and humidity sensor DHT11  includes a built-in resistive humidity sensor and a thermistor for temperature measurement. These two sensing elements work together to provide temperature and humidity readings.

This sensor module communicates with a microcontroller or other digital devices using a digital signal. It sends data in a serial format, where the microcontroller can read the temperature and humidity values from the sensor.

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.
