Description
The sensor is used to detect fire. It is powered with the voltage from 3.3 V to 5.3 V. The range of the sensed wave: from 760 nm to 1100 nm. The output is an analog voltage and digital signal which changes status when exceeding a given potentiometer threshold. The device operates in temperatures from -25 °C to 85 °C.
| Despite the fact that the module detects a fire, it has not an anti-fire protection. Therefore, the distance from the fire should be preserved to prevent damaging of the board. |
The connector cable is connected with female tips, to the module.
Sensor maintenance
The sensor has an analog input that should be connected to the pin of the converter A/C (analog input inArduino). It also has a digital output, which sensitivity level can be adjusted using the integrated potentiometer.
| Pin | Description |
|---|---|
| VCC | Supply voltage from 2 V to 5 V. |
| GND | The ground of the system. |
| AOUT | Analog output with voltage proportional to the level of fire detection. |
| DOUT | Digital output which sensitivity is set using the potentiometer. |
|
The product is compatible with Arduino The manufacturer has prepared a user guide along witha sample program for Arduino and STM32. |
