DS4-NH3-100 Three-electrode Electrochemical Gas Sensor
Detection Principle:
Based on printed solid polymer electrochemical sensing technology with a three-electrode design. The sensor utilizes three electrodes made of noble metals, interacting with target gases through a porous membrane. When gas diffuses into the sensor, oxidation or reduction reactions occur, triggering an electrochemical reaction that generates a current proportional to the gas concentration.
Features:
Wide Voltage Range: Operates at 3.3V–12V DC (recommended 5V DC).
Broad Temperature Range: Functions at -40°C to +55°C without temperature compensation.
Superior Performance: Excellent linearity and fast response for real-time monitoring; long-term zero-point stability with anti-poisoning design for extended service life.
Easy Integration: Compact standard 4-series industrial size (20×16.6mm cylindrical) for seamless integration into new or existing products.
Low Power Consumption: Customizable sleep/wake function suitable for IoT and battery-powered applications; no preheating required, operational immediately after power-up.
Convenient Output: Supports simple UART digital output (3.3V half-duplex single-wire mode) for easy data collection and integration with microcontrollers or IoT systems.
High Precision: Professionally gas-calibrated at the factory, with calibration data stored in the sensor microprocessor for plug-and-play use. Diffusion-based calibration simulates real-world conditions to enhance accuracy.
Intelligent Safety: Self-identifies gas type and detection range; user-definable encryption codes ensure device compatibility and prevent errors; hot-swappable design, offline calibration protocols, and factory reset reduce maintenance downtime and avoid direct exposure to hazardous gases during servicing.
Output Type: UART digital signal output (3.3V half-duplex single-wire mode).
Operating Voltage: 3.3–12V DC (recommended 5V DC).
Physical Parameters:
Dimensions: 20mm (diameter) × 16.6mm (height).
Weight: Lightweight (inferred from dimensions, specific value not specified).
Environmental Parameters:
Operating Temperature: -40°C to +55°C.
Operating Humidity: Within common environmental humidity ranges (details refer to product manual).
Application Fields:
Chemical Industry: Monitors ammonia leakage and controls concentration in chemical production to ensure safety and environmental quality.
Animal Husbandry: Measures ammonia concentration in farms to support animal health and environmental optimization, reducing harm to animals and staff.
Environmental Protection: Monitors atmospheric ammonia for environmental quality assessment and pollution control.
Other Fields: Applicable to sites where ammonia may be generated, such as refrigeration systems and wastewater treatment plants, for real-time concentration monitoring to prevent leaks and ensure safety.
