Renesas SGAS701 Hydrogen (H2) Gas Detection Sensor - Solid-State Chemiresistor, Diffusion
The Renesas SGAS701 is a solid-state chemiresistor sensor module designed for precise hydrogen (Hâ‚‚) detection from 10 to 1000 ppm. It features an integrated heater and operates on a 2.5-5.0 VDC sensing voltage, making it suitable for integration into safety systems, leak detectors, and portable analyzers.
Features
- High-sensitivity solid-state chemiresistor for hydrogen (Hâ‚‚) detection from 10 to 1000 ppm.
- Fast response time of 15 seconds at 100 ppm concentration.
- Integrated heater operates at 5.4 VDC to maintain optimal sensing temperature of 240°C.
- Wide operating environment: -20°C to 50°C and 0-90% RH (non-condensing).
- Low flow rate dependence for stable readings in varied conditions.

The SGAS701 sensor utilizes a nanostructured metal oxide (MOx) sensing material whose electrical resistance changes upon interaction with hydrogen gas molecules at elevated temperatures. This chemiresistive principle provides a reliable and measurable output proportional to gas concentration. An integrated heater ensures the sensing element is maintained at its optimal operating temperature of 240°C for consistent performance.
Designed for robustness, the sensor operates reliably across an environmental temperature range of -20°C to 50°C and humidity up to 90% RH (non-condensing). Its solid-state construction offers excellent long-term stability and resistance to poisoning, making it suitable for continuous monitoring applications in industrial and safety-critical environments.
