Product specifications 1. Utilizing a premium dual-panel design, it includes a power indicator and a TTL signal output indicator; 2. It provides a DO switch signal (TTL) output along with an A0 analog signal output; 3. The valid TTL output signal is at a low level. (When the output is low, the signal light illuminates and can be directly connected to a microcontroller or relay module); 4. The voltage of the analog output rises with increasing concentration;
5. It is highly sensitive for detecting methane and natural gas; 6. It features four screw holes for convenient placement; 7. Dimensions of the product: 3.2cm(L) * 2.0cm(W) * 1.6cm(H); 8. It offers a prolonged lifespan and dependable stability; 9. It exhibits a quick response recovery feature.
Specifications of the product include: 1. Input voltage of 5V DC. 2. Current draw of 150mA. The digital output (DO) provides TTL levels of 0 and 1, corresponding to 0.1V and 5V. 3. The analog output (AO) ranges from 0.1 to 0.3V, indicating low pollution levels, with a high concentration voltage near 4V.
Gentle reminder: Once the sensor is activated, it requires approximately one minute to warm up before the readings stabilize. The heating of the sensor is a standard occurrence due to the presence of an electric heating wire inside. If it overheats, that would indicate a problem.
The VCC and GND of the smoke sensor module are linked to the 5V and GND of the development board, respectively. The AO pin of the module connects to the analog pin A0, while the DO pin connects to digital pin 2 on the development board.
