Integrated Air Quality Sensor Module AM1008W Applications ▪ Air purifier ▪ Air quality monitor ▪ Air conditioner ▪ Ventilation system ▪ Consumer electronic products ▪ Environmental monitoring Description AM1008W is an indoor air quality sensor module with highly integrated ultra-thin laser particle sensor, NDIR CO2 sensor, semiconductor VOC sensor, temperature and humidity sensor, which can real-time output digital measurement data. It is with stable performance, compact structure design, multi-function and optional connection ways, which can be widely used for IAQ monitor, air purifier, ventilation...

Note 1: In normal IAQ applications, accuracy is defined after minimum three (3) ABC periods of continuous operation with ABC on. Some industrial applications do require maintenance. Contact Cubic for further information. Note 2: Specification is referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (±2% currently) is to be added to the specified accuracy for absolute measurement.

The interface connector is located at the side of the sensor. Corresponding female plug part number is A1251WR-S-4P from CJT. The pitch is 1.25mm. The connection cable with female connector at both ends can also be customized.

Application Circuit UART TTL 3.3V UART output Test scenarios 3: 3.3V-5V switching circuit diagram If host MCU is 5V, it need to add the chip and circuit at the communication port (RX, TX) to make 5V transfer to 3.3V.

Measured error: under 25°C±2°C, 50±10%RH, 0~1000pg/m3, consistency and accuracy of PM2.5 is ±15% reading or ±15pg/m3, whichever is larger. Temperature influence coefficient: 0.5%/°C~1%/°C or 0.5pg/m3/°C~ 1pg/m3/°C, whichever is larger.

Product Installation ▪ When install AM1008W module in your system or equipment, please make sure of unobstructed air-inlet and airoutlet. And there is no huge airflow faced to air-inlet and air-outlet. ▪ In order to avoid dust deposition on the surface of sensitive component (laser diode and photosensitive diode), which may affect the measurement accuracy of the sensor, the appropriate installation ways are recommended as below. Recommended Installation , Cross section The blue is the front of laser diode

User Attention ▪AM1008W sensor module is for household electronics products. For application of medical, mining, disaster preparedness, which needs high security and high dependence, this sensor is not suitable. ▪The laser dust sensor adopts non-static adsorption materials such as metal, please avoid to working under the high particle concentration environment. ▪When you use the laser dust sensor, please make sure of unobstructed air-inlet and air-outlet. The CO2, VOC using diffusion for sampling, the gas diffusion hole should be reserved. ▪This sensor module should avoid working outdoors or...

1). The data in this protocol are all hexadecimal data. Such as "46 for decimal [70]" 2). [xx] for single-byte data (unsigned, 0-255); high byte of double byte data is in the front, the low byte in the back 3). Baud rate: 9600, data bits: 8, stopbits:1, parity: No. Sending format of software:

Function: CO2 calibration Statement: Format statement: 1. Calibration target value = DF1*256+DF2 2. Before CO2 calibration, make sure that the current ambient CO2 value is the target value you want to calibrate and that the stable time is at least 2 minutes. 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=02 is measurement open; DF1 =01 is measurement close; 2. When respond command, DF1=02 is measurement open; DF1=01 is measurement close; 3. When the sensor receives command...

Send: 11 01 0D E1 // read particle measuring time Response: 16 03 0D FF FF DC // read successfully 4.5 Set up Timing Measuring Mode Send: 11 03 05 DF1 DF2 [CS] // set up particle measuring mode Send: 11 01 05 E9 // read particle measuring mode Response: 16 03 05 DF1 DF2 [CS] Function: Read particle measuring time Note: 1. Particle measuring mode value X = DF1*256+DF2, unit is second; 2. When X >=60, it means module is under timing measuring mode. Measurement timing cycle is X seconds. The sensor module will start measurement every X seconds. Default measuring time is 36 seconds. 3. Range for...

The laser diode turns off for 11 seconds, enters the standby state, and outputs the B value. After the first 30 second period, the sensor starts a new 3 second measurement and outputs the A value. © If | A-B |> 10 ^g / m3 or | A-B | / B> 10%, the sensor selects Dynamic mode 1. The sensor measures continuously for 16 seconds and outputs the C value. The laser diode turns off for 11 seconds, enters the standby state, and outputs the C value. © If | A-B | <10 ^g / m3 or | A-B | / B <10%, the sensor selects Dynamic mode 2 and stores A value, then enters standby state for 27 seconds and outputs A...
