PS-NH3-100 Ammonia Module

Product catalog summary

Brief Introduction: The PS-NH3-100 Ammonia Module utilizes fuel cell technology for accurate NH3 monitoring. It converts NH3 concentration into PPM using a novel sensor and advanced electronics. The module is pre-calibrated and ready for integration, with no consumable parts ensuring long service life.

Key Features: The module offers selective NH3 detection, high precision, fast response, long service life, high stability, and low power consumption. It is suitable for applications like smart toilets, pig farms, green buildings, and intelligent homes.

Pin Definitions: The module has four pins: Vin (5V), GND, RXD (0～3.3V data input), and TXD (0～3.3V data output).

Technical Specifications: The module operates on a micro fuel cell principle, detecting NH3 in the range of 0-100ppm with an overload capacity of 500ppm. 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 120 seconds, and a recovery time (t10) of less than 180 seconds. It operates within a temperature range of -40℃ to 70℃ and a humidity range of 10% to 90% RH (non-condensing). The module has a storage condition of 3 years, a lifetime of 12 months, and a warranty period of 10g.

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.

Checksum Calibration: A function is provided for checksum calibration to ensure data integrity.

Notes: Users are advised to avoid changing or moving the sensor or electronic elements on the PCB, and to protect the module from organic vapors, solvents, high gas concentrations, excessive vibration, and shock.

PS-NH3-100 Ammonia Module, works on the proven fuel cell technology, is specified developed for the accuracy monitoring of NH3. The module combines novel NH3 sensor with advanced electronic control technology, converting NH3 concentration into PPM directly. Once NH3 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-NH3-100 is pre-calibrated in the factory and can be integrated into your system directly. There’s...
