The PMS7003M with Sensor Modules 48x37x12mm RoHS manufactured by Plantower is an air quality monitoring sensor that combines multi-sensor technology for built-in dust and gas detection. Its features include a wide voltage range of 3.3-6V (typ) with an on-board Low Noise Spread Spectrum Clock (LNSSC) to reduce noise interference. Its built-in detector has high sensitivity, a low supply current, and a long life cycle for reliable performance. Additionally, the integrated detector uses a mature digital and analog signal processing technology to achieve stable, accurate, and fast index measurement.
