DS4-H2S Smart Digital Gas Sensor Solid Polymer Electrochemical Three Electrodes
DS4 uses advanced printed solid polymer electrochemical sensing technology and a three-electrode layout to provide accurate and reliable measurements for a wide range of applications. Its powerful microprocessor, high-precision ADC and intelligent algorithms enable optimal data acquisition and processing.
Low Power, Sleep Mode, and Wide Supply Range – Operates efficiently from 3.3V to 12V DC (5V recommended). User-defined sleep and wakeup modes. Consumes only nA, ideal for low-power battery or IoT applications.
Reliable performance in extreme conditions – Operates over a wide temperature range (-40°C to +55°C) without temperature compensation.
Excellent long-term stability and durability:
Long-term zero stability ensures long-term accuracy.
Fast response time detects changes in gas concentration in real time.
Excellent linearity ensures precise measurements.
Anti-poisoning design extends sensor life
