4.3 Open and Close Particle Measurement Send: 11 03 0C DF1 1E CS Response: 16 02 0C DF1 CS Function: open and close particle measurement Statement: 1. When send command, DF1=2 is measurement open; DF1=1 is measurement close; 2. When respond command, DF1=2 is measurement open; DF1=1 is measurement close; 3. When the sensor receives command for measurement open, it will go into continuous measuring mode; If send: 11 03 0C 02 1E C0 // open particle measurement Respond: 16 02 0C 02 DA // the sensor module is under measurement open status If send: 11 03 0C 01 1E C1 // close particle measurement...

This is an I2C protocol for AM4100. The sensor module is lower computer, it is not able to initiate communication automatically. Communication is initiated via main control board, it reads data and sends control commands. Communication clock frequency is <=30 Khz. START: start signal, send by main controlled board. STOP: stop signal, send by main controlled board. ACK: acknowledge signal, send by the sensor module if in bold; otherwise, send by main controlled board; NACK: non-acknowledge signal, send by the sensor module if in bold; otherwise, send by main controlled board; Dx: receive and...
