Zhengzhou Winsen Electronics Technology Co., Ltd Byte9 Note: Item ((Byte11*256+Byte12)-500)*0.1℃=26.5℃ For example (negative temperature): byte11=0x01, byte12=0x59 3. Checksum calculation Check value=(invert( Byte1+Byte2+...+Byte7))+1 Or Check value=(invert( Byte1+Byte2+...+Byte24))+1 Note: 1. PM2.5 sensor collection hole is the internal airflow inlet, which needs to maintain good contact with the outside air; the fan installation position is the internal airflow outlet of the sensor. When the sensor is installed, please avoid strong airflow around the sensor; if it cannot be avoided, try to...

Zhengzhou Winsen Electronics Technology Co., Ltd www.winsen-sensor.com 4. The PM2.5 sensor on this module is suitable for the detection of dust particles in ordinary indoor environments. The actual use environment should try to avoid soot environment, excessive dust particles, high humidity environment, such as: kitchen, bathroom, smoking room, outdoor, etc. If used in such an environment, appropriate protective measures should be added to prevent viscous particles or large particles from entering the sensor, forming a buildup inside the sensor, and affecting the sensor's performance. 5. The...
