PS-VOC-100 Air Quality Module

Product catalog summary
Brief Introduction: The PS-VOC-100 air quality module utilizes fuel cell technology to convert VOC content into PPM. It features high stability, good consistency, long service life, and requires no baseline correction or periodic calibration. It is suitable for air cleaners, air conditioners, indoor air quality monitoring, portable devices, and smart homes.
Definition of Pins: The module has four pins: Vin (5V), GND, RXD (0-3.3V data input), and TXD (0-3.3V data output).
Technical Specification: The module operates on a micro fuel cell principle, detecting indoor air quality with a range of 0-100ppm and an overload capacity of 200ppm. It requires an input voltage of 4.5-7V, has a warm-up time of less than 3 minutes, a response time (t90) of less than 90 seconds, and a recovery time (t10) of less than 120 seconds. It operates within a temperature range of -40℃ to 60℃ and a humidity range of 10%-90% RH. The module has a lifetime of 5 years and a warranty period of 12 months.
Communication Protocol: The module uses serial communication with a baud rate of 9600, 8 data bits, 1 stop bit, and no parity bit. It supports active upload and Q&A communication types, with commands for switching modes and reading gas concentration.
Notes: Users should avoid changing or moving the sensor or electronic elements on the PCB, and protect the module from organic vapors, solvents, high gas concentrations, excessive vibration, and shock.

PS-VOC-lOO Air Quality Module Brief Introduction PS-VOC-lOO air quality module, works on the proven fuel cell technology, combines solid electrolyte with noble metal catalyst, converting VOC content into PPM directly. Once VOC arrives at working electrode (anode) it is oxidized instantaneously to generate an electrical signal. The electrical signal is then acquired and processed by microprocessor into a PPM value and is output by standard digital signal. PS-VOC-lOO is pre-calibrated in the factory and can be integrated into your system directly. Key Features High stability Good consistency Long...
