FAQ
1. What is a Methane (CH₄) Sensor used for?
A Methane Sensor is designed to detect and measure the concentration of methane gas in the air. It is commonly used in industrial plants, pipelines, smart homes, and IoT safety systems to prevent gas leaks and ensure safe ventilation.
2. How accurate is the Methane Sensor?
Our CH₄ Sensor is factory calibrated with an accuracy of ±3% of the reading (typical). It provides reliable, repeatable measurements even under varying temperature and humidity conditions.
3. Can this sensor be connected to Arduino, ESP32, or other IoT platforms?
Yes. The sensor supports digital communication interfaces such as UART or I²C, making it easy to integrate with Arduino, ESP32, Raspberry Pi, and other microcontroller or IoT systems.
4. Does the Methane Sensor require regular calibration?
Each sensor is factory calibrated before shipment. For long-term or industrial use, periodic verification every 12–24 months is recommended to maintain optimal accuracy, depending on the environment and usage frequency.
5. What is the detection range and response time?
The sensor accurately measures methane concentrations from 0 to 10,000 ppm with a rapid response time of ≤ 2 seconds (T90), allowing real-time leak and safety monitoring.
6. How long is the lifetime of the sensor?
Under normal indoor or semi-industrial conditions, the typical lifespan of the methane sensor is 5 years or longer. It maintains less than 1% signal drift per year for stable long-term performance.
7. Is it suitable for outdoor or high-humidity environments?
Yes, the sensor can operate in –20°C to +60°C and 0–95% RH (non-condensing) humidity. For harsh or semi-outdoor conditions, protective enclosures are recommended to ensure consistent operation.
