ATRS-1031 aerosol sensor is an infrared (LED) particle sensor for automobiles. The sensor can effectively monitor the dust concentration released before the thermal runaway trigger of lithium-ion batteries, and transmit the measurement signal via CAN communication to battery management system (BMS), to formulate safer early warning strategies. This solution has remarkable characteristics such as fast response time, less cross interference, low power consumption, long life and high reliability. Features • Light scattering (LED) technology to report thermal runaway events in lithium-ion battery packs • Aerosol threshold value of 5000 µg/m³ allows early detection of thermal runaway events • Wake-up output and request input for high reliability system integration • Mature vehicle level circuit design suitable for various automotive application • Key components are self-made to ensure quality and long life span • Low power consumption mode available • CAN communication Specifications • Operating Principle: PM (Particulate Matter): Infrared Scattering • Detection Category: PM (Particulate Matter) • Measurement Range: PM：0-10000ug/m³ • PM Resolution: 1ug/m³ • PM Accuracy : ±15% of reading @5000ug/m3 (room temperature) • Data Refresh Time : ≤1s • Digital Output : CAN2.0 • Working Condition : -40℃~+85℃；0~99%RH (non-condensing) • Storage Condition : -40℃~+95℃；0~99%RH (non-condensing) • Working Pressure : 60kPa~120kPa • Power Supply : 6~16VDC (standard voltage 12V DC)
