Zhengzhou Winsen Electronics Technology Co., Ltd UART(TXD) data transmitter UART(RXD) data receiver Communication Protocol 1. General Settings Table 3 Baud Rate Data Byte Stop Byte Check Byte 2. Communication Commands There are two kinds of communication, initiative upload mode and question & answer mode. Default settings is initiative upload mode. Modules upload gas concentration value every other 1S, Note: The module will automatically switch to Q&A mode (question & answer mode) after an inquiry command is received; The module will automatically switch to initiative upload mode if no inquiry...

Zhengzhou Winsen Electronics Technology Co., Ltd To read gas concentration, command line format as follow: Stable5. Byte0 Start Byte (High Byte) Sensor’s return value as follow: Stable6. Byte0 Start Byte (High Byte) Gas concentration value = The low 5 bit of High Byte*256+Low Byte. 3. Check sum and calculation Installation instruction This module connects with external part by adopting Pin2.54mm*4 single-row inserting pin. Cautions 1 .Following conditions must be prohibited 1.1 Exposed to organic silicon steam Sensing material will lose sensitivity and never recover if the sensor absorbs organic...

Zhengzhou Winsen Electronics Technology Co., Ltd 2 . Following conditions must be avoided 2.1 Water Condensation Indoor conditions, slight water condensation will influence sensors’ performance lightly. However, if water condensation on sensors surface and keep a certain period, sensors’ sensitive will be decreased. 2.2 Used in high gas concentration No matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensors characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely damage. 2.3 Long time storage The sensors resistance...
