1、 Introduction to Smoke Detection Sensor Module

The BYG511-YW series smoke sensor adopts the metal oxide principle gas sensor, with output signals such as TTL and IIC. It is designed for low-cost application users of integrators and can be freely integrated. It is widely used in various monitoring and monitoring solutions. It has an intrinsic safety design, can be equipped with electric hot plugging, simplified peripheral circuits, personalized data calibration and calibration programs, and can freely switch sensor probes (of the same model, so that the sensor life can be freely replaced when it reaches its limit). At the same time, it supports similar packaging such as oxygen cells and 2pin electrodes. It is fully compatible with standard inner diameter explosion-proof detection heads and suitable for rapid prototyping monitoring solutions and environmental gas monitoring systems.

precautions

1. Sensors are not ordinary electronic components and require careful protection, which users must take seriously.

2. Long term exposure to high concentrations of chemical vapor or dust will cause sensor readings to drift.

3. During production, use, and transportation, it is necessary to ensure that sensors are kept away from high humidity, high temperature, and high concentration chemical solvents.

4. Avoid using volatile glue, adhesive tape, self-adhesive stickers, or volatile packaging materials, such as foamed plastic bags, foamed plastics, etc.

5. Ventilation is necessary in production environments.

6. Connect the circuit according to the pin diagram.

7. During the use or embedding of other structures, it is necessary to ensure complete contact with the external air.
